Method and device for generating a single-use financial account number
First Claim
1. A device for providing a single-use credit card number, the device comprising:
- a central processor;
an input device in communication with the central processor;
a display in communication with the central processor; and
a storage device in communication with the central processor, the storage device including;
a first data element that is specific to a credit card account, andinstructions adapted to be executed by the central processor to;
receive a request by a user to generate a single-use credit card number;
access the first data element;
receive, via the input device, transaction-specific data comprising at least one of the following;
an amount of a purchase, oran identifier that identifies a merchant,combine the first data element and the transaction-specific data to produce a single-use credit card number that identifies the credit card account, in which the single-use credit card number is recognizable by a credit card authorization system as a credit card number, anddisplay the single-use credit card number via the display.

Abstract
A device for facilitating financial account transactions is described which includes a processing unit including a cryptographic processor. The device also includes an input unit, a display unit and a memory device connected to the processing unit. The memory device contains a private cryptographic key, a first data element and a second data element. The processing unit encrypts the first data element using the private cryptographic key and the second data element, modifies the second data element, combines the encrypted first data element and the second data element to generate a single-use financial account identifier, and displays the single-use financial account identifier. This identifier is then transmitted to a central processor for authorization of the transaction. The central processor extracts and decrypts data elements from the transmitted identifier using the private cryptographic key, compares those data elements with data elements stored in a memory, and verifies the single-use financial account identifier in accordance with the comparison.
