Biometric identification device providing format conversion functionality and method for implementing said functionality

摘要

A biometric authentication device is provided comprising a first interface, a second interface, a processing unit and an output. The first interface is for receiving a live biometric signal associated to a person. The second interface is for receiving information from a contactless chip. The information received at the second interface includes first information conveying a certain format associated with the contactless chip, and the second information conveying biometric data and being in the certain format. The certain format is selected from a set of possible formats. The processing unit is in communication with the first interface and the second interface and is operative for converting the second information to a common reference format at least in part on the basis of the first information. The processing unit is also adapted for deriving authentication information associated to the person and for releasing a signal conveying the authentication information.
