IPC: G07C9/00
Filed: 1988-08-30
Abstract: A security device for identifying the user of the device has a non-volatile memory which stores picture data representative of a picture of the users face. When the device, which may be in the form of a key with electrical contacts, or a card, is presented to a key reading terminal (48), the picture data is read from the memory and decoded to produce a picture on a display (42) which can then be visually compared with the user by security personnel.
