Title:
CHECK AUTHORIZATION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO2003007526
Kind Code:
A3
Abstract:
A self-authenticating check authorization system and method includes a check that has standard bank and account information printed on the MICR line (530), as well as a one-way hash value that is computed based on the standard bank and account information as well as a personal identification code of a customer (330) and a key. The scanned MICR line (530) data is provided to a check verifier (520), which also receives the personal identification code from the customer (330). The check verifier performs a hashing algorithm on the received data, and compares the computed hash value to a hash value obtained from the scanned MICR line data (530). If there is a match, the check is verified (520); if not, the check is not verified.
