Abstract

A wireless phone or other wireless device is utilized to authorize debit transactions from a bank or financial institution in a secure manner in which a one-time meaningless transaction number is displayed to the user at the point of purchase terminal, which the user enters into his wireless phone or other wireless device to authorize the transaction. In one embodiment, the individual uses the device to call the mobile commerce server, and is identified by means of a Wireless Application Protocol ID, or equivalent. The user then enters a PIN number to authorize the transaction. The individual may also select from the wireless device the particular bank from which the debit is to come. In one embodiment, the mobile phone user then goes to the cash register and tells the clerk that this is a mobile commerce transaction. The transaction amount and the identity of the store is transmitted to the mobile commerce server, and the mobile commerce server transmits back to the register a one-time only transaction number which is displayed to the individual or automatically transmitted to the user'"'"'s wireless device. The individual views the transaction number at the register and enters this number via the keypad into the wireless device if it has not already been automatically transmitted. The transaction number along with the PIN number or personal ID number and selected bank is then transmitted to the mobile commerce server, which authorizes and completes the sale, the fact of which is then transmitted back to the register. In so doing, casual observers will, if anything, obtain the transitory transaction number, which is meaningless. Moreover, any apparatus at the register, which would normally be utilized to transact the business, even if tampered with, would have no effect on the subject system since the apparatus, which initiates this transaction, is the wireless device, which is in the possession of the user as opposed to unscrupulous store employee or other miscreant.

a communication channel from said financial institution to said terminal for transmitting a transaction identification number to said terminal;

a display at said terminal for displaying said transaction identification number; and

a wireless transmitter in the possession of said individual for transmitting a predetermined code identifying said individual and said displayed transaction identification number to said financial institution, the receipt of which by said financial institution causing authorization of disbursement of said amount.

2. The system of claim 1, wherein said predetermined code is a personal identification number.

3. The system of claim 1, wherein said predetermined code is the electronic serial number of said wireless transmitter.

4. The system of claim 1, wherein said wireless transmitter includes a selector for selecting which financial institution is the one from which said disbursement is to be made, said wireless transmitter transmitting said selected financial institution identification to the selected financial institution.

5. The system of claim 4, wherein said selected financial institution identification is transmitted with said predetermined code.

6. The system of claim 5, wherein said predetermined code is entered into said wireless transmitter and is transmitted to said financial institution prior to the individual arriving at said terminal, whereby the entry of said predetermined code can be made in secret.

7. The system of claim 6, and further including a transaction timeout and wherein said authorization from said wireless transmitter must arrive before said timeout to authorize said disbursement.

13. The method of claim 2, wherein the predetermined code and the financial institution number are entered into the wireless transmitter at a location remote from the location at which the individual enters in the transaction number.

8. A method for securely authorized disbursement of funds from a financial institution comprising the steps of:

providing a wireless transmitter to an individual seeking the disbursement;

transmitting a transaction identification number to the site of the authorization;

entering the transaction identification number into the wireless transmitter; and

transmitting the entered number to the financial institution for authorization of the disbursement.

9. The method of claim 8, wherein the transaction identification number is unique to the transaction and changes from one transaction to the next.

10. The method of claim 8, wherein the step of transmitting includes transmitting a predetermined code identifying the individual authorizing the disbursement.

11. The method of claim 10, wherein the predetermined code is entered into the wireless transmitter at a location remote from the location at which the individual enters in the transaction identification number, both code and transaction number being necessary to authorize disbursement from the financial institution.

12. The method of claim 8, wherein the transmitting step includes transmitting a financial institution identification number for selecting from which financial institution the disbursement is to be made.

14. The method of claim 8 and further including the step of authorizing the disbursement only if the authorization is made within a predetermined time after transmission of the predetermined code.
