A biometric authentication and/or identification accessory for a mobile device 401 (e.g. mobile phone) is disclosed. The accessory includes a biometric sensor (306), a wireless transmitter (305) and a controller (302) wherein the controller is adapted to: receive a biometric signal 507 from a user via the biometric sensor; identify the user from the signal and generate a signal in response thereto; and send the signal (602) wirelessly through the transmitter to the mobile device to at least partially unlock a function on the mobile device. The biometric sensor could be a bio-potential waveform (e.g. electrocardiogram) sensor comprising a pair of electrodes (203a,b) mounted on the accessory. |
