Electronic Transaction System
FIELD OF THE INVENTION
The present invention relates generally to transaction verification and billing systems
BACKGROUND OF THE INVENTION
Electronic transactions, such as those performed via credit and debit cards, have become common Clearly, it is of great convenience to customers if they need not carry large amounts of cash One limitation often encountered by customers, however, is the size of the transaction Credit card companies typically have a minimum transaction value that they will accept Transaction size limitations are also imposed by vendors, because of transaction fees they must pay to credit card companies Many small retail businesses, for example, grocery stores, may not accept credit cards for this reason Both vendors and customers would benefit from the ready availability of electronic transactions with no size limitation
A logical extension of the convenience to a customer of not carrying cash would be not to need to carry credit cards at all The so-called "electronic wallet" was to be a step in that direction, wherein one smartcard would replace cash and a collection of credit cards, but it has not gained wide acceptance, perhaps because of the need for a mechanically intricate, and therefore, expensive, reader and interface
A convenient means to effect cashless transactions of any size, acceptable to both vendors and purchasers, would be valuable to both and would encourage increased trade
Electronic transactions have been addressed by a number of existing patents, for example, U S Patent Numbers 5,892,891, 5,903,830, 5,805,719, and 5,557,518, but the issues addressed are enhanced security and verification systems and methods in using credit and debit cards or the like, or in accessing computer systems TJ S Patent Number 5,204,902 teaches a cellular telephony authentication arrangement which is merely a security arrangement for use of cellular telephone communication
SUMMARY OF THE INVENTION
The present invention seeks to provide a method and system for effecting electronic transactions between a vendor and a customer with no transaction size limitations and wherein the transaction is performed via the customer's communications device and the associated communications service provider, with no need for the customer to provide a separate identifying card such as a credit card
There is thus provided, in accordance with a preferred embodiment of the invention, a method of effecting a transaction between a vendor and a customer which includes the following steps selecting at least one item for purchase, entering item-associated data into a cash register associated with the vendor; establishing a communications link between a mobile telephone unit associated with the customer and a telephone interface device connected between the cash register and a telephone line associated with the vendor, entering, via a data entry device associated with the mobile telephone unit, customer validating information and transaction information, including a transaction sum, verifying customer validating information and the transaction information, and debiting the mobile telephone account of the customer and crediting a preselected vendor account by an amount corresponding to the transaction sum Further, in accordance with a preferred embodiment of the present invention, the step of verifying transaction information includes the substep of comparing the item-associated data entered into the cash register with analogous transaction data entered via the mobile telephone unit
Additionally, in accordance with a preferred embodiment of the present invention, the method includes, after the step of crediting, the step of providing a readable confirmation of the transaction to the customer and, if required, to the vendor
Further in accordance with a preferred embodiment of the present invention, the step of establishing a communications link includes the substeps of: contacting, via the mobile telephone unit, the telephone line associated with the vendor; entering, via a data entry device associated with the mobile telephone unit, a transaction code to identify the call as a transaction call; and routing the identified transaction call to the telephone interface device. Additionally, the step of establishing includes the substeps of either: retrieving, from the selected cash register connected with the telephone interface device, or entering, via a data entry device associated with the mobile telephone unit, a code identifying a selected cash register on which said step of entering item-associated data was performed, and verifying, via the code identifying a selected cash register, that the selected cash register is associated with the telephone interface device.
There is further provided, in accordance with a preferred embodiment of the present invention, a telephone interface device connecting a cash register and a telephone associated with the vendor from whom a customer has selected an item or items for purchase and a system employing the telephone interface device, for performing the abovementioned method of enacting a transaction a vendor and a customer, by means of a communications device associable with a communications service provider associated with the customer, which includes: a cash register associated with the vendor; and the telephone interface device which is connected between the cash register and a telephone associated with the vendor. The telephone interface includes: a front end module to route incoming calls on the phone line associated with the vendor and a processing module for processing transaction calls which includes: a data processor, a data storage device, and programs for processing transaction-associated data and customer validating data and for generating transaction commands.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to Figure 1, there is shown a block diagram of a system, referred to generally as 10, for effecting a transaction between a vendor and a customer, constructed and operative in accordance with a preferred embodiment of the present invention The transaction system 10 of the present invention has three parties to a transaction a vendor 12, a customer 14, and a communications service provider 16 In a preferred embodiment of the present invention, communications service provider 16 is a cellular telephone service provider, but alternatively, it may be any communications service provider that can connect a user, in this case the purchaser, to a telephone, in this case that of the vendor, for example, a paging or other electronic message service Vendor 12 has a cash register 122 which is connected to a telephone interface device in accordance with a preferred embodiment of the system 10 of the present invention Customer 14 has a communications device 142, having associated therewith an account with a communications service provider 16 In a preferred embodiment of the present invention, communications device 142 is a cellular telephone with an associated telephone account with a cellular telephone
service provider 16, although it may be some other communication device that is associated with a communications service provider and that allows data input; for example, a paging device with a keypad or one that has voice recognition capability. In the following description, customer communications device 142 is referred to as a cellular phone or cellphone, but this is done strictly by way of example.
A method of effecting transactions between vendor 12 and customer 14, in accordance with a preferred embodiment of the present invention, is shown schematically in the flow chart in Figure 2. The step in the method of linking communication device and interface, referenced as 23, is shown in greater detail in the flowchart of Figure 3. In the following description, steps of the method shown in the flow charts in Figures 2 and 3 are indicated by reference numbers in parenthesis, while parts of the system shown in Figure 1 are followed by inline reference numbers.
In accordance with the present invention, after customer 14 has selected an item or items for purchase from vendor 12 (21), vendor 12 enters details of the item or items into cash register 122 as in any standard credit transaction (22). Customer 14 then uses cellular telephone 142 to call the telephone number of vendor 12 (23) (31) and enters a predetermined code, via the keypad of cellular telephone 142 to identify the call as a transaction call, as well as a password or personal identification number (PIN) for security and verification purposes. The cellular telephone service provider 16 system detects the transaction code (32) and validates cellular telephone 142 of customer 14 by verifying that the PIN entered is the correct one for the customer's cellular phone number (34). Transaction calls for which customer validation fails are simply not put through (35), i.e. connected, while calls without the transaction code are put through as standard calls (33).
Associated with the telephone line of vendor 12 is telephone interface device 124 which has a front end module 126, which may be implemented either in software or hardware, for receiving and routing all incoming calls and a processing module 125 for processing of transaction calls. Standard calls are routed to a fixed wire telephone 127 (33) which is located on the vendor premises, and calls identified as transaction calls are passed through to processing module 125 of telephone interface device 124 (23) (36), which includes data storage, a processor, and programs, for further processing of transaction calls.
Processing module 125 of telephone interface device 124 is also associated with cash register 122 via both a physical connection and a cash register identification code to allow transactions and charges only from an authorized cash register 122 (37). If the cash register identification code does not match that authorized for processing module 125 of telephone interface device 124, no transaction calls will be processed (38). Alternatively, customer 14 enters, via cellular telephone 142 keypad, the cash register identification code for cash register 122 whereby the selected items are being purchased, and processing module 125 of telephone interface device 124 verifies that the entered code matches that for the cash register associated therewith. For a vendor having multiple cash registers, each cash register is provided with an identifying code which allows association with a particular telephone interface device 124 for processing transactions therefrom. In an alternative embodiment of the present invention, telephone interface device 124 may be associated with a plurality of cash registers, and the cash register identification codes allow proper accounting of transactions performed on different cash registers.
Once communication is established between purchaser cellular telephone 142 and telephone interface device 124 (23), so as to inherently authorize the cellular phone 142 for use in performing the transaction (25) via cash register 122 (39), customer 14 enters, via the keypad of cellular telephone 142 or by means of voice recognition input therewith, data about the current transaction (24), including at least the transaction sum. In an alternative embodiment of the present invention, customer 14 enters the transaction sum when making the call, together with the transaction code and the PIN, and, in the event of authorization, the transaction sum is passed through directly to telephone interface device 124. At the same time, the transaction data is passed from cash register 122 to telephone interface device 124, which compares it with the transaction data entered via cellular telephone 142 (26). If the sums for the transaction match, the transaction is authorized. Alternatively, additional transaction data may be compared and checked. Customer 14 may also be prompted to confirm the transaction via cellular telephone 142.
Telephone interface device 124 sends the authorized transaction amount and other details of the transaction as needed to communications service provider 16, which bills or debits the telephone account of customer 14 by an amount equal to the transaction sum
(27) and authorizes credit of an amount equal to the transaction sum to a preselected account 128 designated by vendor 12 for that purpose (28). In a preferred embodiment of the present invention, preselected vendor account 128, is a telephone account, to take advantage of the common practice of telephone service providers crediting and debiting multiple telephone service providers for calls and services provided and handled by a number of telephone service providers. Cash register 122 may also issue a printed receipt of the transaction for customer 14 and optionally for vendor 12 (29).
In practice, cellular communications provider 16 may, by prior agreement, collect fees from vendor 12 and possibly customer 14 for providing the above described transaction service. Customer 14 benefits from the convenience of being able to make purchases of any size through an existing account with communications service provider 16 and having all these transactions appearing on one statement from cellular telephone service provider 16. Vendor 12 benefits from increased business volume because of the ease of performing transactions, especially low value transactions which credit card companies do not normally handle.
It will further be appreciated, by persons skilled in the art, that the scope of the present invention is not limited by what has been specifically shown and described hereinabove, merely by way of example. Rather, the scope of the present invention is defined solely by the claims, which follow.
