Abstract

A biometric authentication device is provided comprising a first interface, a conversion database a second interface, a processing unit and an output. The first interface is for receiving a live biometric signal associated to a person. The conversion database has a plurality of entries associated to respective formats and including conversion instructions for converting information from each of the respective format into information into a common reference format. The second interface is for receiving information from a contactless chip including information conveying a certain format associated with the contactless chip. The processing unit is operative for deriving authentication information associated to the person. In the absence of an entry in the conversion database associated to the certain format, the processing unit is operative for establishing a communication link with an external entity for issuing a request to receive conversion instructions for converting information in the certain format to information in the common reference format. The processing unit receives a signal conveying conversion instructions for converting information in the certain format to information in the common reference format and updates the conversion database to include an entry associated to the certain format. The output is for releasing a signal conveying the authentication information.
