Abstract
A personal authorisation device wearable by a user includes an input operable to receive data for authenticating a user, a memory operable to store validation information derived from the user authentication data, and an output operable to provide an authorisation code. The device further includes a tamper detector that triggers if the device is removed from its wearer. Triggering of the tamper detector serves to disable use of the device.
