2). Discussion of Related Art
A customer who visits a store often uses a point-of-sale instrument such as a bank card or a credit card to pay for an item or items that are being purchased. The point-of-sale instrument communicates with a point-of-sale device such as a credit card reader. The point-of-sale device forms part of a point-of-sale network that communicates a charge request to a merchant acquirer computer system and the merchant acquirer computer system routes the charge to credit card and issuer computer systems forming part of the point-of-sale network. The credit card and issuer computer systems may for example include a credit card account to which an amount recorded on the point-of-sale device can be charged if sufficient funds or credit are available. The credit card and issuer computer systems then return a confirmation through the merchant acquirer computer system to the point-of-sale device that the transaction is good, whereafter an operator of the point-of-sale device will allow the customer to leave the store with the item or items that are being purchased.
Electronic transactions can be conducted in a similar manner. In the case of electronic transactions, a user can enter details of a point-of-sale instrument into an interface. Once the details are received, a charge request can be transmitted to a merchant acquirer computer system, and then be processed in a similar manner.
The invention provides a computer system for managing electronic transactions, including a server computer system including a processor, a computer-readable medium connected to the processor, a network interface device connected to the processor and a set of instructions on the computer-readable medium, the set of instructions being executable by the processor and including a data store, a plurality of consumer accounts stored in the data store, each consumer account having a first consumer account identifier, a stored value in the consumer account, a data retrieval module retrieving credits of at least a first type from a carrier computer system over a network interface device, a data communication gateway transmitting the credits of the first type over the network interface device to a consumer device, and receiving a transfer selection from the consumer device based on the transmission to the mobile device, a credit-to-currency converter converting at least some of the credits of the first type to a credit amount, a transfer execution module increasing the stored value based on a credit amount in response to the transfer selection, and notifying, with the processor, the carrier computer system of the credit amount over the network interface device, a communication and routing module that receives a charge request over the network interface device, the charge request including an amount and a second consumer account identifier and identifies a selected one of the consumer accounts by associating one of the first consumer account identifiers with the second consumer account identifier; and an account lookup and debit module that reduces the stored value based on the amount.
The invention also provides a computer-based method of managing electronic transactions, including storing, with a processor, a plurality of consumer accounts in a data store, each consumer account having a first consumer account identifier, saving, with the processor, a stored value in the consumer account, retrieving, with the processor, credits of at least a first type from a carrier computer system over a network interface device, transmitting, with the processor, the credits of the first type over the network interface device to a consumer device, receiving, with the processor, a transfer selection from the consumer device based on the transmission to the mobile device, converting at least some of the credits of the first type to a credit amount, increasing, with the processor, the stored value based on a credit amount in response to the transfer selection, notifying, with the processor, the carrier computer system of the credit amount over the network interface device, receiving, with the processor, a charge request over the network interface device, the charge request including an amount and a second consumer account identifier, identifying, with the processor, a selected one of the consumer accounts by associating one of the first consumer account identifiers with the second consumer account identifier; and reducing, with the processor, the stored value based on the amount.
The invention is further described by way of example with reference to the accompanying drawings, wherein:
The server computer system 12 includes a plurality of consumer accounts (only one consumer account 28 shown), a consumer account setup module 32, a consumer account management system 34, a plurality of merchant accounts (only one merchant account 36 shown), a merchant account management system 38, a transaction clearing system 40, and a voucher management system 42.
As shown in
When the mobile application 208 is initially downloaded onto the mobile device 24, a consumer is provided access to the consumer account setup module 212. The consumer can enter a Mobile Subscriber Integrated Services Digital Network Number (MSISDN) 222 and a password 224 into the interface 210. The MSISDN 222 and the password 224 are received as a MSISDN 226 and a password 228 within the consumer account setup module 212 and are transmitted by the consumer account setup module 212 in
Referring now to
The consumer account management system 34 includes a login module 70, and a settings and payment system 72. A consumer at the mobile device 24 in
The settings and payment system 72 includes a funding source storing module 80, a funding module 82, an account lookup and credit module 84, an automatic top-up settings module 86, an automatic top-up execution module 88, and a rule storing module 90.
The consumer account management module 214 of the mobile application 208 in
The funding source 246 in
The consumer account infrastructure 16 then makes a determination whether sufficient funds are available within the consumer account funding infrastructure 16 to allow for a transfer of the credit value 98. At 104, the consumer account funding infrastructure 16 utilizes the IP address received at 102 to transmit a top-up confirmation to the funding module 82. A top-up confirmation is only transmitted if sufficient funds are available within the consumer account funding infrastructure 16 to cover the credit value 98. If insufficient funds are available within the consumer account funding infrastructure 16, then no top-up confirmation will be transmitted at 104 and a decline signal will instead be transmitted to the funding module 82.
If a decline signal is received by the funding module 82 from the consumer account funding infrastructure 16, the funding module 82 transmits a message to the mobile device 24 in
The consumer at the mobile device 24 in
The automatic top-up execution module 88 periodically, e.g. daily, reads the automatic top-up selector 114. The automatic top-up execution module 88 only executes the funding module 82 if the automatic top-up selector 114 is set to an “ON” status for automatic top-up, and if other limits have been reached such as the end of a one-month period has been reached and the stored value 96 is below the ceiling value. The automatic top-up execution module 88 therefore does not execute the funding module 82 if either the automatic top-up selector 114 is set to “OFF” indicating no automatic top-up, or if such other limits have both been reached.
When the automatic top-up execution module 88 executes the funding module 82, the automatic top-up execution module 88 transmits a credit value 98 to the funding module 82 and the funding module 82 then transmits the credit value 98 in the funding request 102 to the consumer account funding infrastructure 16. The credit value 98 may for example be the difference between the stored value 96 and the ceiling value. Upon a favorable top-up confirmation 104, the funding module 82 then automatically transmits the MSISDN 66 and a credit value 98 at 106 to the account lookup and credit module 84 for increasing the stored value 96 by the credit value 98. The stored value 96 is thus automatically updated based on the automatic top-up selector 114.

3). Transferring Credits from a Carrier Account
The carrier computer system 404 includes a number of carrier accounts (only one carrier account 406 is shown) and an Application Programmable Interface (API) 408. The carrier computer system 404 also includes a number of exchange rates 410 and 412 for credits of first and second types respectively. The carrier account 406 includes a username 414 and a secret key 416. The carrier account 406 also includes credits 418 and 419 of a first type and a second type respectively. The credits 418 and 419 may for example be airtime minutes that are available to the consumer of the carrier account 406, a number of Short Message Service (SMS) messages, data, etc. In the present example the exchange rate 410 relates to conversion of the credits 418 to a currency value and the exchange rate 412 relates to conversion of the credits 419 to a currency value.
The credit-to-currency transfer system 402 includes an authorization credential storing module 420, an authorization module 422, a data communication gateway 424, a data retrieval module 426, a credit-to-currency converter 428, and a transfer execution module 430.
When the consumer selects the selection for “Convert Carrier Credits to Cash” in
The data retrieval module 426 then utilizes the credit-to-currency converter 428 to convert all the credits 418 to a currency amount and all the credits 419 to a currency amount. The credit-to-currency converter 428 simply multiplies the number of credits 418 with the exchange rate 410 to determine a currency amount for the credits 418. The credit-to-currency converter 428 also multiplies the number of credits 419 with the exchange rate 412 to determine a currency for the credits 419. The credit-to-currency converter 428 then provides the currencies for the respective credits 418 and 419 to the data retrieval module 426. The data retrieval module 426 then transmits conversion data 460, including the respective credits and currency amounts, through the data communication gateway 424 to the mobile device 24. The conversion data 460 is received as conversion data 462 within the credit-to-currency transfer module 400 and is displayed as conversion data 464 within the interface 210.
As further illustrated in
In a similar manner, the consumer has moved the slider for SMS messages to 50 messages, which is calculated at a partial credit amount of $3.57, and has selected data of 0.5 MB for $10.33. The total of the partial credit amounts comes to $25.83.
The view of
The transfer execution module 430 receives the transfer selection 470 through the data communication gateway 424. The transfer execution module 430 communicates interactively with the credit-to-currency converter 428 and through the data communication gateway 424 with the mobile device 24 to continuously provide an updated partial credit corresponding to each one of the credits 418 and 419. The transfer execution module 430 first notifies the API 408 of the partial credit selected by consumer. In the present example, the consumer has selected 200 minutes, which is deducted by the carrier computer system 404 from the credits 418 so that the credits 418 are used from 410 minutes to 210 credits minutes. Similarly, the credits 419 are reduced from 220 SMS messages to 170 SMS messages.
At 472, the transfer execution module 430 notifies the account lookup and credit module 84 of the credit value $25.83 and provides the respective MSISDN 66 to the account lookup and credit module 84. The account lookup and credit module 84 then increases the stored value 96 in a manner similar to the manner described with respect to
As shown in
The merchant account management system 38 includes an interface 134, a login module 136, an upload and payment module 138, and a consumer targeting system 140.
A merchant at the merchant computer system 20 can login to the merchant account 36 by downloading the interface 134 and entering a merchant account ID 142 and a password 144 via the interface 134 into the merchant account management system 38. The login module 136 then compares the merchant account ID 142 and the password 144 with the merchant account ID 130 and password 132 to identify and provide access to the respective merchant account 36. The login module 136 then at 146 authorizes access to the upload and payment module 138 by the merchant computer system 20 only for purposes of the respective merchant account 36 having the merchant account ID 130 matching the merchant account ID 142. At 148, the login module 136 similarly authorizes access to the consumer targeting system 140 by the merchant computer system 20.
The consumer targeting system 140 receives data from the consumer account 28 in
The upload and payment module 138 includes a voucher upload module 154, a payment calculation module 156, and a payment module 158. A merchant at the merchant computer system 20 uses the interface 134 to enter voucher information, including terminal numbers 160, discounts 164 and the total number available 166. The voucher upload module 154 then stores a respective voucher entry 168 in or associated with the merchant account 36 having the merchant account ID 130. The voucher entry 168 includes terminal numbers 170 corresponding to the terminal numbers 160, a discount 174 corresponding to one of the discounts 164, and a total number available 176 corresponding to the total number available 166. By way of example, the terminal numbers 170 may be terminals 2 and 5, the discount 174 may be 50 cents and the total number available 176 may be 60.
Similarly, additional voucher entries can be entered from the merchant computer system 20 through the interface 134 and the voucher upload module 154. Each voucher entry has a respective data set for terminal numbers 170, a discount 174 and the total number available 176. Each voucher entry also has a respective voucher ID 184.
Once the voucher entry 168 has been uploaded into the merchant account 36, the payment calculation module 156 calculates a payment to be made based on the voucher entry 168. In the example, it is assumed that the voucher entry 168 was pre-existing with a certain number, for example 20 as the total number available. The payment calculation module 156 at 190 receives or calculates the number added to the total number available 176. In the present example, the total number available 176 has increased from 20 to 60, such that the number added is 40. The payment calculation module 156 at 192 also receives the discount 174. The payment calculation module 156 then multiplies the number added by the discount 174. In the present example, the number added is 40 and the discount is 50 cents, which results in a payment of $20.
The payment calculation module 156 then submits the $20 charge to the payment module 158. The merchant then enters a payment 194 into the interface 134, which is received by the payment module 158. The payment module 158 communicates with the merchant account payment infrastructure 22 by submitting a charge request and receiving a confirmation to either allow or deny the charge request. In another example, the merchant account 36 may have a stored value 96 that can be updated from a funding source and the payment module 158 can decrement the stored value 96 by entering a debit against the stored value 96.

The point-of-sale network 26 includes a point-of-sale device 278, a merchant acquirer computer system 280, and a credit card and issuer computer systems 282.
The consumer uses the point-of-sale instrument 268 to communicate with the point-of-sale device 278. The point-of-sale device 278 receives the PAN 270 from the point-of-sale instrument 268. In the case where the point-of-sale instrument 268 is a credit card or a bank card, the PAN 270 is located on a magnetic strip and the point-of-sale device 278 is a device that has a magnetic strip reader. In the example where the point-of-sale instrument 268 is an NFC device, the point-of-sale device 278 communicates with the point-of-sale instrument 268 through electromagnetic waves to receive the PAN 270.
The point-of-sale device 278 transmits a charge request 284 to the merchant acquirer computer system 280. The charge request 284 includes the PAN 270, the terminal number of the point-of-sale device 278. The point-of-sale device 278 also transmits the total price of all the items over the internet. Although not shown, the charge request 284 also includes a merchant account ID 130 to determine a merchant account 36 to which the point-of-sale device 278 belongs to.
The merchant acquirer computer system 280 then transmits a charge request 286 to the credit card and issuer computer systems 282. The charge request 286 includes the same data as the charge request 284. The charge request 286 also includes a merchant category code that is provided by the merchant acquirer computer system 280. Different merchant category codes are used for different merchant types, e.g. apparel, restaurant, groceries etc. The point-of-sale network 26 has a number of different credit card and issuer computer systems 282 and the merchant acquirer computer system 280 utilizes the IIN 272 to route the charge request 286 to the appropriate credit card and issuer computer systems 282. The credit card and issuer computer systems 282 then transmit a charge request 288 to the transaction clearing system 40. The charge request 288 includes the same data as the charge request 286. The credit card and issuer computer systems 282 utilize the PAN 270 to route the charge request 288 to the transaction clearing system 40.
The transaction clearing system 40 includes a communication and routing system 290 and a transaction processing system 292. The communication and routing system 290 communicates bidirectionally with the credit card and issuer computer systems 282 and communicates bidirectionally with the transaction processing system 292.
The communication and routing system 290 includes a point-of-sale gateway 294, an MSISDN lookup module 296 and an IAI-to-MSISDN table 298. The point-of-sale gateway 294 receives the charge request 288 from the credit card and issuer computer systems 282. At 300, the point-of-sale gateway 294 provides the IAI 276 in the PAN 270 received in the charge request 288 to the MSISDN lookup module 296. At 302, the MSISDN lookup module 296 utilizes the IAI 276 as an input lookup into the IAI-to-MSISDN table 298. At 304, the MSISDN lookup module 296 receives a MSISDN from the IAI-to-MSISDN table 298. A plurality of IAIs is stored within the IAI-to-MSISDN table 298, each with a respective associated MSISDN. The MSISDN received at 304 corresponds to a specific IAI 276 provided at 302. At 306, the point-of-sale gateway 294 receives the MSISDN from the MSISDN lookup module 296. At 308, the point-of-sale gateway 294 provides a data set to the transaction processing system 292, including the MSISDN retrieved from the IAI-to-MSISDN table 298 via the MSISDN lookup module 296, the terminal number received in the charge request 288, the item identifiers and associated amounts received in the charge request 288, and the respective merchant account ID 130 received in the charge request 288.
The transaction processing system 292 includes an account lookup and debit module 310, a voucher application module 312, an amount validation module 314 and a rule application engine 315.
The account lookup and debit module 310 receives the data set provided at 308 from the point-of-sale gateway 294. At 316, the account lookup and debit module 310 provides a data set to the voucher application module 312, including the MSISDN terminal number, amount and merchant account ID. Referring again to
The voucher lookup module 320 receives the data transmitted at 318 from the voucher application module 312. The voucher lookup module 320 then uses the data received at 318 to determine whether the data matches the data in the voucher entries 168. In each case, both the merchant account ID and the terminal number received in the data 318 are used to determine which ones of the voucher entries 168 have merchant account ID's 130 and matching terminal numbers 170.
The voucher lookup module 320 subsequently retrieves a set of data from an identified voucher entry 168, including the discount 174, in the present example $2, the voucher ID 184 and the total number available 176. The voucher lookup module 320 then makes a determination whether the total number available 176 of the respective voucher entry 168 is more than zero, in which case and only in that case, is the voucher entry 168 still valid. The voucher lookup module 320 also retrieves the merchant account ID 130. For purposes of further discussion, the voucher ID's 184 of the identified voucher entry 168 is still valid and referred to herein as “voucher ID's B.”
The voucher lookup module 320 at 326 submits the voucher ID of the identified voucher entry 168, now referred to as “voucher ID B” to the voucher availability module 322. Referring now to
At 334 the voucher lookup module 320 submits the voucher ID B together with its associated discount, in the present example $2, in a data set to the voucher application module 312. The data set received at 334 by the voucher application module 312 also includes the respective merchant account ID 130 retrieved by the voucher lookup module 320. The voucher application module 312 then calculates a discounted amount based on the amounts received in the charge request minus the discount found for voucher entry (ID?) B. Referring again to
Referring again to
Only if the transaction is validated at 342 at the account lookup and debit module 310 and absent any rules for expense tracking does the account lookup and debit module 310 proceed at 344. At 344, the account lookup and debit module 310 utilizes the MSISDN received at 308 to identify the respective consumer account 28 having a MSISDN 66 matching the MSISDN received at 308.
The account lookup and debit module 310 then reduces the stored value 96 of the respective consumer account 28 having the respective MSISDN 66 by the discounted amount. The consumer account 28 also has a set of previous transactions 346. At 348, the account lookup and debit module 310 records the respective transaction within the transactions 346.
Referring again to
As mentioned, the transaction is recorded within the transactions 346. Referring again to
Voucher entries have been used by way of example to illustrate offers and the way that they are redeemed. The voucher entries may for example correspond to item level discounts. Alternatively, basket level discounts may be provided wherein a discount is given based on an entire purchase of a plurality of items as opposed to individual items of the purchase. It may also be possible that offers may be extended that are not redeemable at server level for any discounts, such as coupons that can be redeemed at a point of sale or advertisements.
As mentioned with respect to
As further shown in
As shown in
As previously mentioned, the amount validation module 314 compares the stored value 96 with the charge amount in the charge request 308 as modified by the voucher application module 312, wherein the stored value 96 is (i) only reduced if the stored value 96 is at least as much as the charge amount and (ii) not reduced if the stored value 96 is less than the charge amount, and transmits the confirmation 362 (i) to accept the charge request only if the stored value 96 is at least as much as the charge amount and (ii) to deny the charge request if the stored value 96 is less than the charge amount. As further illustrated in
In
Should the consumer then open the mobile application 208 in
A setting is also provided for a “Set Aside Budget.” If the “Set Aside Budget” is off, then the stored value 96 is permitted to run down to $0. The stored value 96 can thus be less than the remainder of the budget. By way of example, the remaining budget for “Restaurants” can be $35.00 and the stored value 96 can be at $20.00.
If the “Set Aside Budget” is on, then the stored value 96 can only be reduced down to the remainder of the budget. If for example, if the budget for “Restaurants” has run down from $50.00 to $35.00, then the stored value 96 will not permitted to run down past $35.00. The remainder of the “Restaurants” budget will thus always be usable.
In
In
The rule application engine 315 thus compares the budget amount stored within the rule 122 with the charge amount and the rule application engine 315 then reduces the budget amount with the charge amount. If the rule calls for declining the transaction, then the rule application engine 315 (i) only reduces both the stored value 96 and the budget amount if the budget amount is at least as much (or within the percentage range selected by the consumer,) of the charge amount and (ii) does not reduce the stored value 96 or the budget amount if the budget amount is less than the charge amount, and the account lookup and debit module 310 transmits the confirmation 362 (i) to accept a charge only if the budget amount is at least as much as the charge amount and (ii) to deny the charge request if the budget amount is less than the charge amount. The categories of the budgets are, in each case, compared to the merchant category codes provided by the merchant acquirer computer system 280 in
If the determination at 410 is that there are no Set Aside Budgets then at 418, a determination is made whether the charge amount is less than the stored value 96. If the determination made at 414, 416 or 418 is No, then at 420 the transaction is declined. Following 420, the appropriate notification is sent at 422 as described with reference to
If the determination at 414, 416, or 418 is Yes, then at 424 a determination is made whether the category (merchant category code) of the charge maps to any budgets. If the determination at 424 is No, then at 426 the transaction is confirmed and the appropriate notification is transmitted at 422.
If the determination at 424 is Yes, then at 428 a determination is made whether the charge amount is less than the respective budget amount. If the determination at 428 is Yes, then the charge is confirmed at 426 and the appropriate notification is transmitted at 422.
If the determination at 428 is No, then at 430 a determination is made whether there is a decline setting as described with reference to

The other input/control devices 1160 may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth all serving as forming part of an interface. The input controllers 1600 may be connected to any of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons may include an up/down button for volume control of the speaker 1110 and/or the microphone 1130. The one or more buttons may include a push button. A quick press of the push button may disengage a lock of the touch screen 1120 or begin a process that uses gestures on the touch screen to unlock the device. A longer press of the push button may turn power to the mobile device 24 on or off. The touch screen 1120 is used to implement virtual or soft buttons and one or more soft keyboards.
The touch-sensitive touch screen 1120 provides an input interface and an output interface between the device and a user. The display controller 1560 receives and/or sends electrical signals from/to the touch screen 1120. The touch screen 1120 displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects, further details of which are described below.
A touch screen 1120 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. The touch screen 1120 and the display controller 1560 (along with any associated modules and/or sets of instructions in memory 1020) detect contact (and any movement or breaking of the contact) on the touch screen 1120 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on the touch screen. In an exemplary embodiment, a point of contact between a touch screen 1120 and the user corresponds to a finger of the user.
The touch screen 1120 may use LCD (liquid crystal display) technology, or LPD (light emitting polymer display) technology, although other display technologies may be used in other embodiments. The touch screen 1120 and the display controller 1560 may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with a touch screen 1120.
The user may make contact with the touch screen 1120 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which are much less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.
The mobile device 24 also includes a power system 1620 for powering the various components. The power system 1620 may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.
The software components stored in memory 1020 include an operating system 1260, a communication module (or set of instructions) 1280, a contact/motion module (or set of instructions) 1300, a graphics module (or set of instructions) 1320, a text input module (or set of instructions) 1340, and applications (or set of instructions) 1360.
The operating system 1260 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.
The communication module 1280 facilitates communication with other devices over one or more external ports 1240 and also includes various software components for handling data received by the RF circuitry 1080 and/or the external port 1240. The external port 1240 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.).
The contact/motion module 1300 may detect contact with the touch screen 1120 (in conjunction with the display controller 1560) and other touch sensitive devices (e.g., a touchpad or physical click wheel). The contact/motion module 1300 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred, determining if there is movement of the contact and tracking the movement across the touch screen 1120, and determining if the contact has been broken (i.e., if the contact has ceased). Determining movement of the point of contact may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). The contact/motion module 1300 and the display controller 1560 also detects contact on a touchpad.
The graphics module 1320 includes various known software components for rendering and displaying graphics on the touch screen 1120, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like.
The text input module 1340, which may be a component of graphics module 1320, provides soft keyboards for entering text in various applications (e.g., contacts, e-mail, IM, blogging, browser, and any other application that needs text input). The applications 1360 may include the mobile application 208.
