## Background
BACKGROUND
Historically, when a consumer purchased a good or service, the transaction usually involved use of currency in the form of either cash or a check. With the advent of the credit card and, more recently, the debit card, consumers have lost the tactile experience associated with making a purchase or paying bills. Instead a typical purchase is now streamlined to the point where a consumer slides a card through a machine, optionally enters a personal identification number (PIN), and approves the purchase.
Recent studies show and experts contend that while the new approach to transactions is convenient, the loss of the tactile experience of handling cash to purchase a good or service has desensitized consumers regarding the amount of money actually being spent. In turn, consumers are outspending budgets.

In essence the register module provides the POS with the functionality of a modern electronic cash register.
In one or more embodiments of the invention, the POS is optionally configured to have a funds transfer module (316). The funds transfer module provides functionality consistent with the funds transfer module described as part of the computing device above.
In one or more embodiments of the invention, the POS is operatively connected to a merchant back-end server (318) which is configured to have a processor (330), network interface (328), memory (326), and storage (324). The POS may provide transaction information, including the cost of goods sold, items sold, method of payment, and inventory data, to the server for processing. In one or more embodiments of the invention, the back-end server may be configured with a funds transfer module (320) and a wallet module (322), which are configured in a manner consistent with the descriptions above. The POS (300) may provide the necessary transaction information to the back-end server to facilitate a transfer of funds which is then executed by the back-end server (318). Those skilled in the arts will appreciate that the transaction information provided by the POS (300) to the back-end server (318) may include some or all of the aforementioned information, or an even wider array of data, and that the POS (300) and back-end server (318) may act as an integrated computing device or be separate.
FIG. 4A shows a flow chart in accordance with one or more embodiments of the invention. Initially, a network connection is established between the first computing device (hereafter, “sending device”) and either a POS or second computing device (hereafter, “receiving device”) (ST 400). The sending device pictorially displays currency which is associated with an account (ST 402) and designates an image of the currency for the purpose of either executing a transaction, or manipulating the account data or currency in the account (ST 404). Upon designation of the currency image, the sending device may transmit the currency image data to a receiving device (ST406). As necessary, the sending device may transmit instructions to transfer actual funds consistent with the currency image data that was transmitted to the receiving device (ST 408). Confirmation of the actual transfer of funds may be received by the sending device (ST 410), and a record of the transaction is stored (ST 412).
Pictorial display of the currency associated with an account (ST 402) may require account data to be used as a basis for the display. Account data, including the amount of currency associated with the account and other account data can be obtained in a variety of ways. In one or more embodiments of the invention, the sending device establishes a network connection with a financial entity responsible for maintenance of the account and downloads the data from the financial entity. In one or more embodiments of the invention, the user may directly enter account data through a keyboard or have the information be read from computer readable media. Those skilled in the art will appreciate that input consisting of account information and data can be derived from variety of sources, including, but not limited to those mentioned above.
Pictorially displaying the type and denomination of the currency may also require manipulation of the raw account data. Manipulation of the account data may consist of dividing the currency into different denominations, categorizing the currency by the type of account (e.g., saving, checking, money market, brokerage account, auto loan, or other type of account), combining account balances, setting budgets or limiting currency which may be used, calculating foreign exchange rates, adjusting the account balance after a transaction, applying the currency towards a transaction, categorizing transactions according to time, type and amount, or other manipulation of the account data. Those skilled in the art will appreciate that account information and data may be manipulated in many ways.
As an example of manipulating account information and data for display, in one or more embodiments of the invention, the sending device obtains account data including the available balance in an account given in a particular currency; however, the data must be manipulated to display the currency in a manner more suitable to the user. In doing so, the sending device manipulates and then displays the denomination of currency in a variety of ways. For example, if an account has a currency of 100 bills available, the invention can pictorially display the available balance as one 100 bill, five 20 bills or twenty 5 bills. Of course, the currency can be divided up differently. For example if the display originally showed one stack of 1,000 currency in denominations of 100 bills, the display could be manipulated to show a stack of five 100 bills, a stack of three 100 bills and a stack of two 100 bills. In one or more embodiments of the invention, the data could be manipulated to select a particular bill and “break” it. For instance, a $20 bill of currency may be broken into one $10 bill, one $5 bill, and five $1 bills. The reverse is also true. Several small denominations may be consolidated into larger denominations.
In one or more embodiments of the invention, if a user requests to convert the currency from one type to another, this too is possible. For instance, the same 100 bill of currency X in the account could be displayed as 50 bills of currency Y (assuming an exchange rate of 1X bill for 0.5Y bill). The 50 bills of currency Y may be displayed in various denominations, including, five 10 bills, or two 20 bills and one 10 bill, and so on. Further manipulation of the data may provide a user with images tailored to requests. Manipulation of account information and data may take place at any time, and may be appropriate after account information is downloaded and images are designated for manipulation. It will be apparent to one of ordinary skill in the art that many ways are possible for one to represent a sum of money pictorially by breaking, consolidating, and/or dividing the currency.
The actual format and layout of the pictorial display of currency may be effectuated in several ways at the discretion of the user, determined by limitations or capabilities of the device or determined by other means. In one or more embodiments of the invention, bills and coins are stacked in a three-dimensional representation with each denomination having its own stack. In one or more embodiments of the invention, the face of the bill or the coin is shown with a number associated with each bill representing how many of each denomination are available. In one or more embodiments of the invention, a choice exists regarding the appearance of the bills. In one or more embodiments of the invention, a number representing the total amount of the available balance may be shown. In one or more embodiments of the invention, the display indicates the amount of currency selected for a transaction, the total amount of the transaction, and the amount due. Those skilled in the art will appreciate that currency may be displayed in a multitude of different ways.
Continuing with FIG. 4A, an image of currency may be designated on the sending device (ST 404). Designation of the currency image denotes that the currency may either be manipulated, as described above, or used in a transaction. In one or more embodiments of the invention, the user has the ability to select pictorial images of currency for designation. In one or more embodiments of the invention, the selections may be accomplished on a touch-screen by physically touching the screen to select the currency. Alternatively, the currency may be selected by means of input from a keyboard, joystick, mouse, or other device. In one or more embodiments of the invention, the rules provided by software or a user may be used to dictate the selection of currency. Once the selection is made, the currency selected is then designated for manipulation or use in a transaction. Those skilled in the art will appreciate that designation of the currency image may be achieved in a variety of ways, including, but not limited to the aforementioned methods.
Continuing with FIG. 4A, upon designating the image of currency, the data associated with the currency image may be transmitted to the receiving device (ST 406). This data may, in turn, be used for further completion of a transaction or displaying the image of currency on a receiving device. Additional manipulation of account data may be required to pictorially reflect and account for the currency image transfer. Those skilled in the art will appreciate that the currency image data transmitted to the receiving device will need to encompass information required to further the transaction.
In one or more embodiments of the invention, the transaction may be between two accounts which are both represented on the sending computing device. In this case, image data may not need to be transmitted to a receiving device. For example, if a transaction consisted of transferring currency from a savings account to a checking account transmission of the image data to a receiving device may not be necessary.
Once the currency image data is transferred from the sending device to the receiving device or a transaction is represented, a need exists for a corresponding transfer of actual currency from one account to another in order to reconcile the actual accounts and properly reflect the transfer of currency image data (ST 408). In other words, after the image of currency is transferred, actual payment may need to follow. In order to execute this transaction, the sending device may provide transactional information, including identifying the user account and financial entity, supply authorization information (e.g., user identification, personal identification number), and approval of the transaction. This information may be communicated directly to the financial entity associated with the sending device by means of a network connection, or transmitted to the receiving device to be used in processing the transaction.
In one or more embodiments of the invention, upon completion of the transfer of funds, the sending device may receive a confirmation that the funds are indeed transferred (ST 410). In one or more embodiments of the invention, the sending device may store a record of the transaction (ST 412) either in memory, on a storage device, or on some other computer writable media.
FIG. 4B shows a flow chart in accordance with one or more embodiments of the invention. A receiving device may be a POS or other form of computing device. The receiving device accepts currency image data from a sending device (ST 414) and identifies that data as currency data (ST 416). Images of the currency are then displayed by the receiving device using a predetermined type and denomination of currency (ST 418). The amount of currency represented by the transfer of the currency image data is then quantified (ST 420). The receiving device then executes a transfer of actual funds based on the amount of currency represented by the currency image data (ST 422), receives a confirmation that the transfer of actual funds is complete (ST 424), and stores a record of the transaction (ST 426).
In one or more embodiments of the invention, purchase information may be communicated to the sending device to be used as input to initiate a transaction. For example, if a $50 shirt is being purchased, then the receiving device transmits the sending device an image of $50. In one or more embodiments of the invention, the receiving device functions as a modern electric cash register and is used to calculate purchase information, including the cost of goods or services to be purchased, the subtotal amount, applicable taxes, redemption of coupons or rebates and a final total purchase amount. Those skilled in the arts will appreciate that the receiving device may have the capability to operate as a register and be configured to perform some or all of the aforementioned functions.
The receiving device, in turn, receives currency image data from the sending device representing the amount of actual currency to be transferred (ST 414). In one or more embodiments of the invention, receipt of the data may be facilitated through use of a network connection between the sending and receiving devices, or by other means. The currency image data may include data used to compose the image of currency on the display of the receiving device, as well as the amount, denomination, type and exchange rate of currency represented by the image. Using the currency image data transmitted from the sending device, the receiving device may identify the received image data as data representing currency (ST 416). Those skilled in the art will appreciate that currency image data may consist of more attributes than the aforementioned list.
To use the currency image data received from the sending device, the receiving device may need to manipulate the data. Manipulation of the currency image data may include dividing the currency into different denominations of currency, categorizing the currency by the type of account (e.g., saving, checking, money market, brokerage account, auto loan, or other type of account), combining account balances, setting budgets, restricting currency to be used, calculating foreign exchange rates, adjusting the account balance after a transaction, applying the currency towards a transaction, categorizing transactions according to time, type and amount, or other manipulation of the account data. Those skilled in the art will appreciate that account information and data may be manipulated in many ways and that this manipulation may take place at any time during the processing of a transaction.
The receiving device may display an image of the currency as represented by the image data received from the sending device (ST 418). In other words, the receiving device displays the amount of currency that is transferred by the sending device in accordance with one or more embodiments of the invention. The display of currency may be carried out either pictorially, though the use of text, or by other means. In one or more embodiments of the invention, the currency image data transferred from the sending device is displayed on the receiving device in a pictorial format consistent with the pictorial format of the display on the sending device. Alternatively, the display may be in a pictorial format that does not match the pictorial format used by the sending device, or the currency may be represented in text. Those skilled in the art will appreciate that the representation of currency image data transferred by the sending device can be accomplished in many ways including several different types of pictorial display or the use of text.
The receiving device may quantify the currency represented by the currency image data to determine a transaction amount (ST 420), and then execute a transfer of funds based on the transaction amount (ST 422). In one or more embodiments of the invention, the receiving device may execute a transfer of funds by sending instructions to a financial entity describing the amount of the transaction, the financial entity from which funds will be withdrawn, the financial entity into which funds will be deposited, and authorization, identity and approval information of the parties. Those skilled in the art will appreciate that while some or all of the information mentioned above may be needed to complete a transfer of funds, additional information may be required.
In one or more embodiments of the invention, upon completion of the transfer of funds, the receiving device may receive a confirmation that the funds are indeed transferred (ST 424). In one or more embodiments of the invention, the receiving device may store a record of the transaction (ST 426) either in memory, on a storage device, or on some other computer writable media.
FIGS. 5A, 5B, and 5C show an example in accordance with one or more embodiments of the invention. Specifically, FIGS. 5A, 5B, and 5C show one example of what a user of the systems described in FIGS. 1, 2, and 3 might see.
FIG. 5A shows one example of a user experience using the system to make a purchase at a POS. In (500), the available account balance of $240.50 can be seen on the computing device, both in pictorial form and text form. The POS terminal displays the amount due, $110.30. In (510), the user selects $110.30 with which to pay the amount owed. The user may select the amount due in a variety of ways. For example, the user may use a keypad to type in the amount due. Alternatively, the computing device may be equipped with a touch screen, enabling the user to “drag” money from the available balance side to the payment side, or select money with which to pay. One of ordinary skill in the art will recognize that there are numerous ways with which to input or select the amount due. After selecting the amount due, the user of the computing device transmits that amount to the POS. That amount of money then appears on the POS terminal, indicating that the transfer is completed. In (520), the user may observe the updated account information displayed on the computing device. This may be one of many ways to receive confirmation that the transaction was successfully completed.
FIG. 5B shows another example of a user experience using the system to make a purchase at a POS. The process is the same as described in FIG. 5A, however in this example, the POS is located in a country whose currency is the Euro. In (530), the account balance of the user, $130.20, is displayed in pictorial and textual form on the computing device. The POS displays the amount to be paid, C=32. In (540), the user has selected $52.02 with which to pay the balance. The computing device displays the exchange rate; in this case =C32 is equal to $52.02. After the user selects the amount to pay, that amount is transmitted to the POS, and is displayed in the POS's native currency, Euros. In (550), the updated account balance of the user is displayed on the computing device.
FIG. 5C shows a transfer between two computing devices, device A and device B. In (560), the account balance of the user of device A is shown, and the amount due is shown on computing device B. In (570), the user of device A selects the amount to pay, and transmits it over to device B. Device B receives the amount and displays it on its screen. In (580) the account balances of both users are updated.
Embodiments of the invention may be implemented on virtually any type of computer regardless of the platform being used. For example, as shown in FIG. 6, a computer system (600) includes one or more processor(s) (602), associated memory (604) (e.g., random access memory (RAM), cache memory, flash memory, etc.), a storage device (606) (e.g., a hard disk, an optical drive such as a compact disk drive or digital video disk (DVD) drive, a flash memory stick, etc.), and numerous other elements and functionalities typical of today's computers (not shown). The computer (600) may also include input means, such as a keyboard (608), a mouse (610), or a microphone (not shown). Further, the computer (600) may include output means, such as a monitor (612) (e.g., a liquid crystal display (LCD), a plasma display, or cathode ray tube (CRT) monitor).
