Biometrics for identification

You are right.  However the fingerprints are stored on RFID chips in the passport or identity
card.  Fortunately these chips have high failure rates (sometimes caused by being bended when
carried in a pocket, accidently put into the washing machine or a microwave) and thus there
needs to be a backup scheme without the fingerprints; i.e. the plain old printed/glued-in
picture.
