METHOD FOR PROCESSING USER AUTHENTICATION INFORMATION

摘要

A user authentication information processing method for accurately performing an authentication of a card user is provided to manage a problem from a customer and a member store through user authentication information including card user fingerprint information. User bio information is encrypted and transmitted from a bio-information management server on communication network. The encrypted bio-information is received from a settlement terminal. The encrypted bio-information is stored in a storage media. In case the authentication of a user generating a sales check is requested, the encrypted user bio-information is extracted and interconnected with the storage media. The extracted user bio-information is decoded by interconnecting the bio-information management server on the communication network. User identification information corresponding to the encrypted user bio-information is confirmed.
