Biometric Interface

Abstract:

A device for communication with a terminal. The device comprises: a communication unit for communicating with the terminal; a biometric unit comprising a biometric sensor for sensing biometric data; contacts for connecting the device to the terminal; a first physical interface between the biometric unit and the contacts configured to enable contact communication between the biometric unit and the terminal; and a second physical interface between the communication unit and the biometric unit configured to enable contact communication between the communication unit and the biometric unit. The device is configured such that all contact communications between the terminal and the communication unit are routed through the biometric unit via the first and second physical interfaces.
