1. Field of the Invention
The present invention generally relates to financial transactions and more particularly to facilitating financial transactions over a network.
2. Related Art
In online financial transactions, customers search for and purchase products and services through electronic communications with online merchants over electronic networks, such as the Internet. During the course of these transactions, customers may provide payment in various ways including, for example, credit cards, electronic fund transfers, and other payment techniques offered by payment providers.
Typically, when online shopping at a particular website, customers select items to purchase by clicking on a link for a specific item. The selected items are placed on reserve in some type of virtual shopping cart. When done shopping, the customer proceeds to a checkout page to provide some form of payment for the selected items. At this point in the process, the customer provides some form of identification and payment. When the customer continues shopping and is ready to purchase items from another website, the customer is typically prompted to re-enter some form of identification and payment.
This process can be tedious and inconvenient. Entering information every time an online transaction takes place is inefficient and time consuming. Thus, there currently exists a need to improve the process of purchasing products and services in online transactions.
In accordance with embodiments of the invention, systems and methods for facilitating financial transactions over a network include a merchant device, a client device and a payment processing device. The merchant device is adapted to allow a merchant to provide one or more items for purchase via the network. The client device includes a browser application adapted to allow a user to access the merchant device via the network and view the one or more items for purchase. The client device includes a service application adapted to provide a payment mechanism to the user. The user generates a purchase request for at least one item by selecting the at least one item, dragging the at least one item to the payment mechanism, and dropping the at least one item over the payment mechanism. The payment processing device is adapted to receive the purchase request from the client device via the network and authorize the user to purchase the at least one item from the merchant based on information passed with the purchase request.
In accordance with embodiments of the invention, the merchant device may be adapted to allow a merchant to generate a bill image summarizing the one or more items selected for purchase. The client device may be adapted to allow the user to generate a purchase request for at least one item by selecting the at least one item, instructing the merchant device to generate the bill image summarizing purchase of the at least one item selected for purchase, dragging the bill image to the payment mechanism, and dropping the bill image over the payment mechanism. The payment processing device is adapted to receive the purchase request, including information related to the bill image, from the client device via the network and authorize the user to purchase the at least one item from the merchant based on information passed with the purchase request.
In accordance with embodiments of the invention, systems and methods for facilitating financial transactions over a network include a first component adapted to communicate with a user via a client device over the network and a merchant via a merchant device over a network and a second component adapted to receive a purchase request from the user via the client device over the network and authorize the user to purchase at least one item from the merchant based on information passed with the purchase request. The second component provides a service application to the user as a payment mechanism, and the service application allows the user to generate the purchase request for the at least one item by selecting the at least one item from the merchant device, dragging the at least one item to the payment mechanism, and dropping the at least one item over the payment mechanism.
In accordance with embodiments of the invention, systems and methods for facilitating financial transactions over a network include receiving a purchase request for a selected item from a user via the network. The purchase request includes user information, merchant information, and selected item information embedded as arguments in an expression. The systems and methods include verifying the user information including accessing a user account based on the user information to verify the availability of monetary funds for the selected item and verifying the merchant information including accessing a merchant account based on the merchant information and availability of the selected item related to the selected item information. The systems and methods include processing the purchase request by authorizing the user to purchase the selected item from the merchant based on the verified user and merchant information and completing the purchase request by deducting monetary funds from the user account and crediting the deducted monetary funds to the merchant account.
These and other features and advantages of the present invention will be more readily apparent from the detailed description of the embodiments set forth below taken in conjunction with the accompanying drawings.
Embodiments of the invention and their advantages are best understood by referring to the detailed description that follows. It should be appreciated that like reference numerals are used to identify like elements illustrated in one or more of the figures, wherein showings therein are for purposes of illustrating embodiments of the invention and not for purposes of limiting the same.
Embodiments of the present disclosure enable users to drag-and-drop an image (e.g., icon) of an item (e.g., product or service for purchase) displayed in a graphical user interface (GUI), such as a web browser, to a payment mechanism, such as a desktop image or icon and/or a toolbar. When enabled, the payment mechanism recognizes the selected item and communicates with a payment processing provider to purchase the selected item. In one implementation, the payment processing provider may redirect the user to a page on a merchant site that confirms their purchase of the selected product. The payment mechanism may also take different actions, such as adding the product to a virtual shopping cart and providing buttons to complete the purchase at a later time. In various embodiments, the payment mechanism may be implemented with a browser plug-in, bundled with an existing toolbar or application, or a provided in a frames-based implementation that may not require the user to download an application.
In some implementations, the image on the web page representing an item for purchase may include an image attribute having dynamic arguments identifying the item for purchase as information in a bill or invoice. When enabled, the payment mechanism may transmit a bill or invoice identifier along with a user identifier and/or a merchant identifier to the payment processing provider for payment processing of the purchase. After payment processing is completed, the payment processing provider may inform the merchant of the processing result, which may include a successful payment. In another implementation, the bill or invoice image may be dragged by the user to any of a plurality of payment provider images or icons (e.g., Visa, MC, AmEx, PayPal). Therefore, it should be appreciated that various embodiments of the present disclosure may extend beyond a browser application to other applications that enable dragging-and-dropping of objects, while retaining information associated with the objects.
Embodiments of the present disclosure overcome deficiencies of conventional approaches to processing online financial transactions, wherein the merchant manages a cash register and/or point-of-sale (POS) device and receives credit card information from a client or user. Instead, embodiments of the present disclosure enable a merchant to manage the cash register (e.g., a user's shopping cart) and the payment processing provider manages the POS device and the user's credit card and/or banking information. Thus, the merchant transmits bill or invoice information to the payment processing provider, which handles the payment processing and reports back results thereof, such as success or failure, thereby simplifying the merchant's involvement with the payment transaction.
In one embodiment, the network 160 may be implemented as a single network or a combination of multiple networks.

The user identifier 130 may include attributes related to the user, such as personal information (e.g., a user name, password, photograph image, biometric id, address, phone number, etc.) and banking information (e.g., banking institution, credit card issuer, user account numbers, security information, etc.). In various implementations, the user identifier 130 may be passed with a user purchase request to the payment provider server 180, and the user identifier 130 may be used by the payment provider server 180 to associate the user 102 with a particular user account maintained by the payment provider server 180, in a manner as described herein.
In one embodiment, the one or more merchant servers 140 may be maintained, for example, by one or more merchants offering various items, such as products and/or services, in exchange for financial payment to be received from users, such as the user 102, over the network 160. In this regard, each of the one or more merchant servers 140 may include a database 142 for identifying available products and/or services, which may be made available to the client device 120 for viewing and purchase by the user 102. Accordingly, each of the merchant servers 140 may include a marketplace application 144, which may be configured to provide information over the network 160 to the browser application 122 of the client device 120. For example, the user 102 may interact with the marketplace application 144 through the browser application 122 over the network 160 to search and view various items, products and/or services identified in the database 142.
In one embodiment, each of the one or more merchant servers 140 may include a checkout application 146, which may be configured to facilitate online purchase transactions by the user 102 of products and/or services identified by the marketplace application 144. In this regard, the checkout application 146 may be configured to accept payment information from the user 102 and/or from payment provider server 180 over the network 160.
In one embodiment, each of the one or more merchant servers 140 may include one or more merchant identifiers 148, which may be included as part of the one or more items made available for purchase so that particular items are associated with particular merchants. The merchant identifier 148 may include attributes related to the merchant, such as business and banking information. In various implementations, the merchant identifier 148 may be passed with a user purchase request to the payment provider server 180 when the user 102 selects an item for purchase, and the merchant identifier 148 may be used by the payment provider server 180 to associate a particular item purchased with a particular merchant account maintained by the payment provider server 180, in a manner as described herein.
In one embodiment, each of the one or more merchants having a related merchant server 140 may need to establish a merchant account with the payment provider server 180 so that the payment server provider 180 is able to process transactions having items offered for purchase by the merchants. When establishing a merchant account, each of the one or more merchants may need to provide business information, such as name, address, phone number, etc., and financial information, such as banking information, merchant account information, credit card information, payment processing information, etc.
In various embodiments, as discussed herein, each of merchant servers 140 may be associated with a particular link (e.g., a link, such as a URL (Uniform Resource Locator) to an IP (Internet Protocol) address). In this regard, the payment provider server 180 may optionally redirect the browser application 122 to an appropriate webpage and/or merchant site of the merchant server 140 to facilitate purchase of a corresponding item and/or service available from at least one of the merchant servers 140.
In one embodiment, the payment provider server 180 may be maintained, for example, by an online payment service provider, which may provide payment processing for online transactions on behalf of the user 102 to an operator of the merchant server 140. In this regard, the payment provider server 180 includes one or more payment applications 182, which may be configured to interact with the client device 120 and/or each of the merchant servers 140 over the network 160 to facilitate the purchase of items, products and/or services by the user 102 from the merchant server 140. In one example, the payment provider server 180 may be provided by PayPal, Inc. of San Jose, Calif., USA.
In one embodiment, the payment provider server 180 may be configured to maintain a plurality of user and merchant accounts 184, each of which may include account information 186 associated with individual users, including the user 102, and the one or more merchants associated with the merchant servers 140. For example, account information 186 may include private financial information of user 102 and merchants 140, such as one or more account numbers, passwords, credit card information, banking information, or other types of financial information, which may be used to facilitate online transactions between the user 102 of the client device 120 and one or more merchants associated with the merchant servers 140. As such, the payment application 182 may be configured to interact with the one or more merchant servers 140 on behalf of the user 102 during a transaction with checkout application 146 without requiring the user 102 to provide account information 186 directly to the merchant server 180. In various embodiments, the methods and systems described herein may be modified to accommodate users and/or merchants that may or may not be associated with at least one existing user account and/or merchant account, respectively.
In one implementation, upon user instruction, the service application 126 may be installed and/or run on the client device 120 (block 204). The user 102 may run the browser application 122 on the client device 120 to access at least one merchant website via a related merchant server 140 (block 208) to search the accessed merchant website and view one or more items for purchase (block 212). In one embodiment, upon installation, the user 102 may be prompted to establish a user account with the payment provider server 180, wherein the user 102 may use the client device 120 to access the payment provider server 180 via the network 160. When establishing a user account, the user 102 may be asked to provide personal information, such as name, address, phone number, etc., and financial information, such as banking information, credit card information, etc. In one embodiment, information related to the user 102 may be packaged as the user identifier 130.
Next, the user 102 may generate a purchase request 216 for at least one item by selecting the at least one item (block 220), dragging the at least one item to the service icon (block 224), and dropping the at least one item over the service icon (block 228). In one embodiment, the user purchase request includes user information, merchant information, and selected item information embedded as arguments in an expression, which are passed to the payment provider server 180, in a manner as further discussed herein. The user information may include user identifier information, the merchant information may include the merchant identifier information, and the selected item information may include one or more image attributes, including item identifier information, having dynamic arguments identifying the item and merchant providing the item for purchase.
When enabled, the payment mechanism may transmit the image identifier along with the user identifier 130, the merchant identifier 148 and the item identifier to the payment provider server 180 for payment processing. When selecting an item to purchase, the user 102 may utilize a cursor control component (e.g., mouse) to select and drag an item icon or image, representing a selected item for purchase, from the merchant site to a service icon either on the desktop, in a toolbar, or in the browser. Once the user 102 drops the selected item over the service icon, the user 102 is prompted via, for example, a pop-up window, to provide input of user identification (block 232). However, it should be appreciated that the user identification may be provided as the user identifier 130 and passed with the user purchase request, and the payment provider server 180 may ask for verification of user identification from the user 102.
At this point, the user 102 may provide user identification 186 or at least verify the user identification for a related user account 184 stored in payment provider server 180 so that funds may be deducted from the user account 184 for purchase of the selected item. Once proper user identification is provided and/or verified, the online purchase transaction may be completed (block 236).
It should be appreciated by those skilled in the art that more than one item may be selected for purchase prior to completing the online purchase transaction. For example, a plurality of items may be selected and placed in a virtual shopping cart and then purchased in a single online purchase transaction. Alternately, each item selected for purchase may be purchased separately without departing from the scope of the present disclosure.
In one implementation, upon user command, the service application 126 may be installed and/or run on the client device 120 (block 254). As previously discussed, upon installation, the user 102 may be prompted to establish a user account with the payment provider server 180. The user 102 may run the browser application 122 on the client device 120 to access at least one merchant website via a related merchant server 140 (block 258) to search, view, and select one or more items for purchase from the accessed merchant website (block 262). In one embodiment, more than one item may be selected and placed in a virtual shopping cart for purchase in a single online purchase transaction.
Next, the user 102 may generate a purchase request 216 for the one or more items selected for purchase by instructing the merchant server 140 to generate a invoice image or icon (block 270), dragging the invoice image or icon to the service icon (block 274), and dropping the invoice image or icon over the service icon (block 278). In one embodiment, the user purchase request includes user information, merchant information, and selected item information in the form of an invoice embedded as arguments in an expression, which are passed to the payment provider server 180, in a manner as further discussed herein. In various implementations, the image on the web page representing an item for purchase may include an image attribute having dynamic arguments that may be provided in the invoice or invoice. When enabled, the payment mechanism may transmit a bill or invoice identifier along with a user identifier and merchant identifier to the payment provider server for payment processing. When selecting one or more items for purchase, the user 102 may utilize a cursor control component (e.g., mouse) to select, drag and drop one or more item icons to the virtual shopping cart on the merchant site to create an item purchase list. The user 102 may then instruct the merchant server 140 to generate an invoice summarizing the items selected for purchase, wherein generating the invoice includes generating a invoice image or icon that represents the invoice and information related thereto, including item selection information, item availability information, purchase information, merchant identification information, etc.
After instructing the merchant site to generate the invoice image or icon to represent the selected items for purchase, the user 102 may select, drag and drop the invoice image from the merchant site to a service icon either on the desktop, in a toolbar, or in the browser. Once the user 102 drops the invoice image over the service icon, the user 102 is prompted via, for example, a pop-up window, to provide input of user identification (block 282). However, it should be appreciated that the user identification may be provided as the user identifier 130 and passed with the user purchase request, and the payment provider server 180 may ask for verification of user identification from the user 102.
In various implementations, the image of the invoice representing an item for purchase may include an image attribute having dynamic arguments identifying the merchant, the invoice and/or the one or more items selected for purchase. When enabled, the payment mechanism may transmit an invoice identifier along with a user identifier to the payment processing provider for payment processing of the purchase. The invoice identifier may include information relate to the selected items for purchase along with information related to the merchant including merchant information, such as merchant account information, needed for processing the purchase request.
Next, the user 102 may provide user identification 186 or at least verify the user identification for a related user account 184 stored in payment provider server 180 so that funds may be deducted from the user account 184 for purchase of the one or more selected items. Once proper user identification is provided and/or verified, the online purchase transaction may be completed (block 286).
In one implementation, the payment provider server 180 receives a purchase request from the user 102 via the client device 120 (block 304). As previously discussed in reference to
Upon receiving the user purchase request, the payment provider server 180 determines whether the user 102 is an existing user having an established user account 184 by, for example, checking a user account list in a user account database (block 308). If the user 102 does not have an established user account, then the payment provider server 180 prompts the user 102 to establish a user account 184 by providing user information 186 (block 312), and the payment provider server 180 uploads the service application 126 to the client device 120 so that the user 102 may install and run the service application 126 on client device 120 (block 316). Once the service application 126 is installed and run on the client device 120, the payment provider server 180 processes the purchase information provided in the user purchase request (block 332).
Otherwise, if the user 102 is determined to be an existing user by the payment provider server 180 (block 308), then the payment provider server 180 verifies the user account and user identification information provider by user 102 in the user purchase request (block 320). For example, as previously discussed, the user 102 may be prompted to provide user identification to purchase any selected items and complete the online transaction. Next, the payment provider server 180 may determine if the user account is current and active (block 324). In some instances, a user's account information may need to be updated, and thus, the payment provider server 180 may prompt the user 102 to update user account information 186 in the user account 184 for the user 102 (block 328). If the user account 184 is current and active, then the payment provider server 180 processes the purchase information in the user purchase request (block 332). It should be appreciated by those skilled in the art that the payment provider server 180 may cancel the online purchase transaction at any point in the process if it is determined that the user 102 enters wrong information or the user 102 is trying to purchase an item with criminal intent.
The payment provider server 180 processes the purchase information provided in the user purchase request (block 332). The purchase information may include information related to the item selected for purchase, information related to the merchant providing the item selected for purchase, information related to the user including user account number, balance information, credit card information, etc. In one implementation, the payment provider server 180 may optionally access the merchant site via the merchant server 140 to verify purchase information including verifying that the selected item is available (e.g., in stock), verifying the pricing information, verifying that the merchant account is up-to-date, etc. (block 336). Next, the payment provider server 180 may prompt the user 102 via, for example, a pop-up window, to verify the purchase request (block 340). For example, the payment provider server 180 may ask the user 102 to complete the purchase transaction by selecting a designated box to complete the purchase transaction. In this way, the payment provider server 180 is adapted to allow the user 102 to cancel the online payment transaction prior to completion.
Next, the payment provider server 180 completes the online purchase transaction by deducting the amount of the purchase request from the user account 184 and crediting the amount of the purchase request to the merchant account 184 (block 344). In one example implementation, completing the purchase request may include redirecting the user to a page on the merchant site that confirms their purchase of the selected product to provide, for example, a receipt to the user. The payment mechanism may also take different actions, such as adding the product to a virtual shopping cart and providing buttons to complete the purchase at a later time.
In one implementation, the payment provider server 180 receives a purchase request from the user 102 via the client device 120 (block 404). As previously discussed, the user 102 may initiate a user purchase request by dragging and dropping an item icon of a selected item for purchase over the service icon, which initiates the user purchase request and online transaction with the payment provider server 180.
Next, upon receiving the user purchase request, the payment provider server 180 verifies the user account information including user identification provider by user 102 in the user purchase request (block 420). For example, as previously discussed, the user 102 may be prompted by the payment provider server 180 to provide user identification to purchase any selected items and complete the online transaction.
Next, the payment provider server 180 may prompt the user 102 via, for example, a pop-up window, to verify the purchase request (block 440). For example, as previously discussed, the payment provider server 180 may ask the user 102 to complete the purchase transaction by selecting a designated box to complete the purchase transaction. Next, the payment provider server 180 completes the online purchase transaction by deducting the amount of the purchase request from the user account 184 and crediting the amount of the purchase request to the merchant account 184 (block 444).
