In the past, payments required exchanging currency. Modern times have brought in electronic payments which use cards to represent accounts which may be accessed electronically. Further, payments have become part of applications on computing devices where account numbers may be manually typed in. However, users have become more accustomed to typing less and less. Emoji and abbreviations have become more and more common in communication. However, payments still require the laborious entry of numbers and letters to execute a transaction.
Symbols are used to represent payment accounts. The symbols may be programmed to represent accounts and the data for the accounts may be entered into appropriate fields when the symbol is selected. In some embodiments, the symbol may be selected using a sound or a voice. In other embodiments, the symbols may be selected by touching a symbol on a touch screen. In yet another embodiment, a pointer like a joystick is used to select a symbol. Once selected, account data is retrieved and is communicated to the proper field in the data entry screen. The account data is then used to complete the transaction.
The present invention now will be described more fully with reference to the accompanying drawings, which form a part hereof, and which show, by way of illustration, specific exemplary embodiments by which the invention may be practiced. These illustrations and exemplary embodiments are presented with the understanding that the present disclosure is an exemplification of the principles of one or more inventions and is not intended to limit any one of the inventions to the embodiments illustrated. The invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Among other things, the present invention may be embodied as methods, systems, computer readable media, apparatuses, components, or devices. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment, or an embodiment combining software and hardware aspects. The following detailed description is, therefore, not to be taken in a limiting sense.

Symbols 310 (
Technically, the system and method addresses the technical problem of accurately entering account data on a screen of a limited size. Small keyboards and fat or swift fingers often result in inaccurate data being entered into account fields. The inaccurate data may be flagged as errant or may be seen as fraudulent. Often, the transaction is rejected and the data has to be entered again assuming the underlying account has been locked.
The technical solution greatly reduces the problem of inaccurate typing by replacing typing with simply selecting a symbol. The selection may not even require typing and may be made using a voice command. In other embodiments, the selection may be of a symbol 310 on a display. The selection may use a touch screen, a track ball, a pointer device or the like.
The network 102 may be described variously as a communication link, computer network, internet connection, etc. The system 100 may include various software or computer-executable instructions or components stored on tangible memories and specialized hardware components or modules that employ the software and instructions to receive symbols 310 to enable payments by monitoring communications between users and merchants as well as other parties in the payment ecosystem.
The various modules may be implemented as computer-readable storage memories containing computer-readable instructions (i.e., software) for execution by one or more processors of the system 100 within a specialized or unique computing device. The modules may perform the various tasks, methods, modules, etc., as described herein. The system 100 may also include both hardware and software applications, as well as various data communications channels for communicating data between the various specialized and unique hardware and software components.
The symbol analysis system 110 may include one or more instruction modules including a module 112 that, generally, may include instructions to cause a processor 114 of a symbol analysis server 116 to functionally communicate with a plurality of other computer-executable steps or sub-modules, e.g., sub-modules 112A, 112B, 112C, and components of the system 100 via the network 102. These modules 112A, 1128, 112C may include instructions that, upon loading into the server memory 118 and execution by one or more computer processors 114, determine whether a recognized symbol 310 has been received and may be processed by the payment network system 108. For example, sub-modules may include a first machine learning module 112A, a second machine learning module 1128, a data integration module 112C, etc. A first data repository 122 may store symbol data 122A for entities of the system 100. In some embodiments, further data repositories may correspond to different types of symbol data 122A or sub-components of the symbol data 122A (e.g., a transaction region, transaction type, a time of day, a merchant and/or customer type, a payment device type, a transaction clearing delay, transaction amount, cardholder name, cardholder account number, and other payment network account data 164A, etc.). Various other data 124A may be received and/or derived by the symbol analysis system 110 and stored in a second data repository 124 and used by the system 100 as described herein. For example, the second data repository may be used to store electronic wallet transaction details 124A from an electronic wallet system or other method of electronic or computer-based payment.
The merchant computer system 106 may include a computing device such as a merchant server 129 including a processor 130 and memory 132 including components to facilitate transactions with the user computer system 104 via other entities of the system 100. In some embodiments, the memory 132 may include a transaction communication module 134. The transaction communication module 134 may include instructions to send merchant messages 134A to other entities (i.e., 104, 108, 110, 111) of the system 100 to indicate a transaction has been initiated with the user computer system including payment device data and other data as herein described. The merchant computer system 106 may also include a transaction repository 142 and instructions to store payment and other transaction data 142A within the transaction repository 142. In some embodiments, the merchant computer system 106 may send payment data 143A corresponding to a payment device like a credit card or other account access device to the payment network system 108 or other entities of the system 100, or receive payment data 1438 from the user computer system 104 in an electronic wallet-based or other computer-based transaction between the user computer system 104 and the merchant computer system 106.
A user computer system 104 may include a processor 145 and memory 146.

Referring now to
At block 200, an input of a symbol 310 may be accepted in an input output circuit 924. The symbol 310 may take on a variety of forms. At a high level, the symbol 310 may be a representation of data. Instead of having to manually type in the data over and over using a tiny keyboard, the symbol 310 may be used to represent the data. As an example, instead of having to repeatedly type in a credit card number, a user may be able to simply select a symbol 310 and the data 122A represented by the symbol 310 may be entered in the appropriate fields. The symbol data 122A may include a credit card number, an expiration date, a billing name, a billing address, a security code, etc.
In some embodiments, the symbol 310 may be displayed on a user interface. It may be in an app function such as a browser function that is viewed as a ribbon or defined area 410 (
By selecting the symbol, an application may activate and the application may review the pending display to determine how the data from the symbol 310 may be appropriately placed in the input boxes on the user interface. For example, symbol data 122A may include a bill address and the application may review the pending input field for one labeled “address” or something similar.
The application may using machine learning to assist in placing the proper data in the proper fields. For example, if a field label account address is the appropriate place to enter symbol data 122A entitled billing address for a particular web site, the symbol analysis system 110 may store that information and use it in the future when determining how to fill in input fields in the future. The symbols 310 may be part of a browser extension or may be an aspect of an application that may work with the application through appropriate APIs.
When the symbol analysis system 110 recognizes a payment is occurring, symbols 310 may be displayed. The determination that a payment is occurring may occur in several ways. In some embodiments, separate web pages may be loaded and the symbol analysis system 110 may analyze the page, determine a payment is being made and may execute the symbol analysis system 110. In other embodiments, a user may request that the symbol analysis system 110 start.
As will be described with respect to
As can be seen, the symbols 310 may be larger than a traditional key on a portable computing device keyboard. As a result, the symbols 310 are easier to select and less input errors may occur. Further, the account issuer may be able to create symbols 310 which are visually appealing which may lead to a user selecting to use that account.
In another aspect, the symbols 310 may be illustrated in such a way to remind a user of the account represented by the symbol 310. For example, a blue symbol 310 may represent a first bank account and a red symbol 310 may represent a second account. The illustrations of the symbols 310 may be preset by the symbol 310 provisioner of may be modified by a user. For example, a user may use a photo or drawing as a symbol such as using a photo of a bank or a credit card to be the illustration of the symbol 310. Similarly, the illustration may be provided by the account issue and may be card art that is a scaled down version of a credit card, for example.
In some embodiment, a user interface may allow a user to add accounts and to define the look of the symbol 310. The user interface may be on a portable computing device or may be on a traditional computing device which may make it easier to enter all the desired data. In other embodiments, the symbol 310 is created by the account issue. The user may be able to select the symbol 310 from the account issuer or may select a different symbol 310 from a plurality of symbols 310 or may select to modify the symbol 310 from the account issuer. The illustrations may only be limited by a user's imagination. If a user routinely uses a wearable device like a ring, bracelet or glove to make transactions for a specific account, the symbol may resemble the wearable device.
Logically, the symbols 310 may be used to send value or request value. In addition, the symbol 310 may be intermixed with other emojis or text to create a payment request or a payment. As illustrated in
To ensure security such as when a nefarious person picks up a mobile computing device of another user, verification may be required. As can be imagined, verification may take on a variety of forms. In
In some embodiments, the symbol 310 may be received through a voice command. For example, a user could dictate a text message “Pay Ralph $5 using the blue card.” The symbol analysis system 110 may be physically configured for analyzing the voice signal, determining if the voice signal matches a known signal and if the voice signal matches a known signal, selecting the known signal. For example, when an account is added to the symbol analysis system 110, a user may be able to given it a spoken name like “blue card.” Thus, the symbol analysis system 110 may be able to compare the received voice command to store voice commands to determine which account is being referenced. In addition, machine learning may be used to refine the use of voice to select symbols 310. For example, if the user say “use azul card” and edits the payment to use the blue card on a first transaction, in the future, the system may know to use the blue card when the user requests to use the azul card.
As mentioned previously, a set up methodology may also exist. In one embodiment, the details of a payment device or account such as a credit card may be received. The details of the account may be communicated through the computer network 100 to verify the information is accurate. A verification may then be created to verify the user truly has access to the entered account. In one embodiment, a biometric verification may be used while in other embodiments, a traditional name and password may be used. Assuming the verification is successful, the user may be able to personalize the symbols 310 representing the accounts.
The details may be stored locally in a secure manner. In another embodiment, the details may be stored remotely and may be received in a variety of ways. In some embodiments, encryption is used to safely communicate the data. In other embodiments, a token server may be used and tokens may be exchanged where the tokens are not the actual account numbers but represent the account numbers and are translated by a secure token server.
The symbols 310 may be provisioned in a variety of ways. In one embodiment, the symbols 310 may be provisioned by the account issuer. For example, if the account is a credit account like a credit card, the bank or credit union that issued the credit card may provision the symbols 310. In this way, the symbols 310 may contain identification of the account issuer. The provisioning may occur through the download of an app such as from an app store. In other embodiments, the user may follow a secure link to download the necessary computer instructions to provision the symbols 310.
In some embodiments, the symbols 310 may display additional information to the user. As an example, the symbols 310 available may display an available balance or a current balance due as received or pulled from a payment device issuer system 111, for example. In other embodiments, the balance levels may be indicated by a color such as a low balance due being indicated in green and a high balance due being indicated in red. In yet another aspect, the symbol may change back to a first image or color when communicated to the payment network system 108 such that the receiver may not see the balance or color but only the relevant payment data necessary to complete a transaction.
In other embodiments, a credit card association may provide the app or computer instructions to provision the symbols 310 in a similar manner. In another embodiment, the symbols may reference a virtual wallet executing on the computing device and the symbols may represent accounts present in the virtual wallet.
In yet another embodiment, a third party may create the computer instructions to enable the symbol 310 provisioning. By using a third party, the provisioning may allow for even more customization that from an account issuer. For example, even more customization of the symbols 310 may be available as account issuers may desire to control the look of the symbols 310. As a result, the third party may be able to attract additional users.
In yet a further embodiment, the computer instructions to enable the symbol 310 provisioning may be part of the computing device operating system. For example, a mobile smart phone may use the Android operating system or the Apple® mobile operating system and as part of the operating system, symbol 310 provisioning may be part of the operating system.
In an additional aspect, the symbol 310 may be configured to include sounds or voices. For example, when using the symbols 310 to request payment to the account represented by the symbol 310, a voice may be included saying “The rent is due!” or “this request relates to Acme Corp” which again, may be easier than typing a message using a tiny keyboard on a portable computing device, for example The sound may be included as part of the message communicated to the network 102.
Referring again to
At block 210, the symbol 310 may be recognized. In some embodiment, the simple selection of a symbol 310 may be straightforward. In other embodiments, a user may select between two symbols 310 and the system 100 may be unsure which symbol 310 is being selected. Similarly, if the symbol 310 is a voice input, the voice input may not be understood or may be garbled due to background noise and the symbol 310 may not be recognized. In application, the voice command may be converted in a digital signal and that digital signal may be compared to stored digital signals to determine which symbol 310 is being selected.
Again, machine learning may be used to compare the digital signal to other likely digital signals and suggestions may be made to the user asking for clarification such as “Did you mean the blue card or the bluebird card?” Response to the queries may be used by the machine learning aspects to improve future performance.
At block 215, symbol data 122A represented by the symbol 310 may accessed from a memory. As illustrated in
Logically, the symbol data 122A may be stored locally in a secure manner or may be stored remotely. If the symbol data 122A is stored remotely, a request may be formatted according to a protocol and may be communicated to a remote server according to an application programming interface (API) and the remote server may respond with the symbol data 122A if the request is determined to be legitimate.
At block 220, a data field 720 on the electronic form such as a web site or application may be filled using the symbol data 122A represented by the symbol 310. In some embodiments, the symbol data 122A may be displayed to the user such as in
In some embodiments, the proper entry of the symbol data 122A into the form field 720 may be simple such as placing an account number in an account number field. In other embodiments, the determination may be more complicated. In the trickier situations, the data fields 720 types may be determined, the data types represented by the symbol 310 may be determined, the appropriate symbol data 122A to appropriate data fields 720 maybe determine and the appropriate data 122A may be entered in the appropriate fields 720.
Logically, the system of using symbols 310 may be used in other electronic formats such as email, SMS, iMessages, etc. The symbol analysis system 110 may have to review the messages that are communicated though the network 100 and translate the symbols 310 into actions that are then communicated through the network 100 to the relevant parties. For example, a user may communicate a request for payment using a text message that includes a symbol 310. The payer may respond with a payment text message (which also may include a payer's symbol 310) and the funds may be transferred to the user using the account information and routing information that may be represented by the symbol 310 of the user and logically, the funds may be removed from the payer's account using the routing and account information represented by the payer's symbol 310. A similar process may occur without regard to the form of electronic communication so long as the symbol analysis system 110 has access to the messages and had the necessary tools to understand the messages. For example, if a message is encrypted, the symbol analysis server 110 may need one or more keys to decrypt the message.
As shown in
The processor 902 of
The system memory 912 may include any desired type of volatile and/or non-volatile memory such as, for example, static random access memory (SRAM), dynamic random access memory (DRAM), flash memory, read-only memory (ROM), etc. The mass storage memory 914 may include any desired type of mass storage device. For example, the computing device 901 may be used to implement a module 916 (e.g., the various modules as herein described). The mass storage memory 914 may include a hard disk drive, an optical drive, a tape storage device, a solid-state memory (e.g., a flash memory, a RAM memory, etc.), a magnetic memory (e.g., a hard drive), or any other memory suitable for mass storage. As used herein, the terms module, block, function, operation, procedure, routine, step, and method refer to tangible computer program logic or tangible computer executable instructions that provide the specified functionality to the computing device 901, the systems and methods described herein. Thus, a module, block, function, operation, procedure, routine, step, and method can be implemented in hardware, firmware, and/or software. In one embodiment, program modules and routines are stored in mass storage memory 914, loaded into system memory 912, and executed by a processor 902 or can be provided from computer program products that are stored in tangible computer-readable storage mediums (e.g. RAM, hard disk, optical/magnetic media, etc.).
The peripheral I/O controller 910 performs functions that enable the processor 902 to communicate with a peripheral input/output (I/O) device 924, a network interface 926, a local network transceiver 928, (via the network interface 926) via a peripheral I/O bus. The I/O device 924 may be any desired type of I/O device such as, for example, a keyboard, a display (e.g., a liquid crystal display (LCD), a cathode ray tube (CRT) display, etc.), a navigation device (e.g., a mouse, a trackball, a capacitive touch pad, a joystick, etc.), etc. The I/O device 924 may be used with the module 916, etc., to receive data from the transceiver 928, send the data to the components of the system 100, and perform any operations related to the methods as described herein. The local network transceiver 928 may include support for a Wi-Fi network, Bluetooth, Infrared, cellular, or other wireless data transmission protocols. In other embodiments, one element may simultaneously support each of the various wireless protocols employed by the computing device 901. For example, a software-defined radio may be able to support multiple protocols via downloadable instructions. In operation, the computing device 901 may be able to periodically poll for visible wireless network transmitters (both cellular and local network) on a periodic basis. Such polling may be possible even while normal wireless traffic is being supported on the computing device 901. The network interface 926 may be, for example, an Ethernet device, an asynchronous transfer mode (ATM) device, an 802.11 wireless interface device, a DSL modem, a cable modem, a cellular modem, etc., that enables the system 100 to communicate with another computer system having at least the elements described in relation to the system 100.
While the memory controller 908 and the I/O controller 910 are depicted in
The system 900 may include but is not limited to any combination of a LAN, a MAN, a WAN, a mobile, a wired or wireless network, a private network, or a virtual private network. Moreover, while only one remote computing device 930 is illustrated in
Additionally, certain embodiments are described herein as including logic or a number of components, modules, or mechanisms. Modules may constitute either software modules (e.g., code or instructions embodied on a machine-readable medium or in a transmission signal, wherein the code is executed by a processor) or hardware modules. A hardware module is tangible unit capable of performing certain operations and may be configured or arranged in a certain manner. In example embodiments, one or more computer systems (e.g., a standalone, client or server computer system) or one or more hardware modules of a computer system (e.g., a processor or a group of processors) may be configured by software (e.g., an application or application portion) as a hardware module that operates to perform certain operations as described herein.
In various embodiments, a hardware module may be implemented mechanically or electronically. For example, a hardware module may comprise dedicated circuitry or logic that is permanently configured (e.g., as a special-purpose processor, such as a field programmable gate array (FPGA) or an application-specific integrated circuit (ASIC)) to perform certain operations. A hardware module may also comprise programmable logic or circuitry (e.g., as encompassed within a general-purpose processor or other programmable processor) that is temporarily configured by software to perform certain operations. It will be appreciated that the decision to implement a hardware module mechanically, in dedicated and permanently configured circuitry, or in temporarily configured circuitry (e.g., configured by software) may be driven by cost and time considerations.
Accordingly, the term “hardware module” should be understood to encompass a tangible entity, be that an entity that is physically constructed, permanently configured (e.g., hardwired), or temporarily configured (e.g., programmed) to operate in a certain manner or to perform certain operations described herein. As used herein, “hardware-implemented module” refers to a hardware module. Considering embodiments in which hardware modules are temporarily configured (e.g., programmed), each of the hardware modules need not be configured or instantiated at any one instance in time. For example, where the hardware modules comprise a general-purpose processor configured using software, the general-purpose processor may be configured as respective different hardware modules at different times. Software may accordingly configure a processor, for example, to constitute a particular hardware module at one instance of time and to constitute a different hardware module at a different instance of time.
Hardware modules can provide information to, and receive information from, other hardware modules. Accordingly, the described hardware modules may be regarded as being communicatively coupled. Where multiple of such hardware modules exist contemporaneously, communications may be achieved through signal transmission (e.g., over appropriate circuits and buses) that connect the hardware modules. In embodiments in which multiple hardware modules are configured or instantiated at different times, communications between such hardware modules may be achieved, for example, through the storage and retrieval of information in memory structures to which the multiple hardware modules have access. For example, one hardware module may perform an operation and store the output of that operation in a memory device to which it is communicatively coupled. A further hardware module may then, at a later time, access the memory device to retrieve and process the stored output. Hardware modules may also initiate communications with input or output devices, and can operate on a resource (e.g., a collection of information).
The various operations of example methods described herein may be performed, at least partially, by one or more processors that are temporarily configured (e.g., by software) or permanently configured to perform the relevant operations. Whether temporarily or permanently configured, such processors may constitute processor-implemented modules that operate to perform one or more operations or functions. The modules referred to herein may, in some example embodiments, comprise processor-implemented modules.
Similarly, the methods or routines described herein may be at least partially processor-implemented. For example, at least some of the operations of a method may be performed by one or processors or processor-implemented hardware modules. The performance of certain of the operations may be distributed among the one or more processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the processor or processors may be located in a single location (e.g., within a home environment, an office environment or as a server farm), while in other embodiments the processors may be distributed across a number of locations.
The one or more processors may also operate to support performance of the relevant operations in a “cloud computing” environment or as a “software as a service” (SaaS). For example, at least some of the operations may be performed by a group of computers (as examples of machines including processors), these operations being accessible via a network (e.g., the Internet) and via one or more appropriate interfaces (e.g., application program interfaces (APIs).)
The performance of certain of the operations may be distributed among the one or more processors, not only residing within a single machine, but deployed across a number of machines. In some example embodiments, the one or more processors or processor-implemented modules may be located in a single geographic location (e.g., within a home environment, an office environment, or a server farm). In other example embodiments, the one or more processors or processor-implemented modules may be distributed across a number of geographic locations.
Some portions of this specification are presented in terms of algorithms or symbolic representations of operations on data stored as bits or binary digital signals within a machine memory (e.g., a computer memory). These algorithms or symbolic representations are examples of techniques used by those of ordinary skill in the data processing arts to convey the substance of their work to others skilled in the art. As used herein, an “algorithm” is a self-consistent sequence of operations or similar processing leading to a desired result. In this context, algorithms and operations involve physical manipulation of physical quantities. Typically, but not necessarily, such quantities may take the form of electrical, magnetic, or optical signals capable of being stored, accessed, transferred, combined, compared, or otherwise manipulated by a machine. It is convenient at times, principally for reasons of common usage, to refer to such signals using words such as “data,” “content,” “bits,” “values,” “elements,” “symbols,” “characters,” “terms,” “numbers,” “numerals,” or the like. These words, however, are merely convenient labels and are to be associated with appropriate physical quantities.
Unless specifically stated otherwise, discussions herein using words such as “processing,” “computing,” “calculating,” “determining,” “presenting,” “displaying,” or the like may refer to actions or processes of a machine (e.g., a computer) that manipulates or transforms data represented as physical (e.g., electronic, magnetic, or optical) quantities within one or more memories (e.g., volatile memory, non-volatile memory, or a combination thereof), registers, or other machine components that receive, store, transmit, or display information.
As used herein any reference to “some embodiments” or “an embodiment” or “teaching” means that a particular element, feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. The appearances of the phrase “in some embodiments” or “teachings” in various places in the specification are not necessarily all referring to the same embodiment.
Some embodiments may be described using the expression “coupled” and “connected” along with their derivatives. For example, some embodiments may be described using the term “coupled” to indicate that two or more elements are in direct physical or electrical contact. The term “coupled,” however, may also mean that two or more elements are not in direct contact with each other, but yet still co-operate or interact with each other. The embodiments are not limited in this context.
Further, the figures depict preferred embodiments for purposes of illustration only. One skilled in the art will readily recognize from the following discussion that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles described herein.
Upon reading this disclosure, those of skill in the art will appreciate still additional alternative structural and functional designs for the systems and methods described herein through the disclosed principles herein. Thus, while particular embodiments and applications have been illustrated and described, it is to be understood that the disclosed embodiments are not limited to the precise construction and components disclosed herein. Various modifications, changes and variations, which will be apparent to those skilled in the art, may be made in the arrangement, operation and details of the systems and methods disclosed herein without departing from the spirit and scope defined in any appended claims.
