Method for testing biometric identifier of e.g. fingerprint of fingers of user to clear user for payment service, involves changing stored biometric reference identifier determined by positive comparison based on last biometric identifier

摘要

The method involves transferring a current biometric identifier, which is detected by a detecting device in a detecting function block (1), of a user to a server via a network. The detected identifier is compared with a portion of reference identifiers of a registered user in a comparing function block (2) during testing the biometric identifier by the server. The user is cleared for an inquired service after the positively completed comparison. A stored biometric reference identifier determined by the positive comparison is changed based on the last biometric identifier detected for testing. The detecting device is an iris scanner.
