Abstract
Data key actuated devices such as high security doors are modified so that they periodically transmit an identity pattern. An authorized user is provided with a portable access device storing keys for a number of such key actuated devices, with each key associated with an identity pattern for that device. The portable access device has a stored template comprising a fingerprint of the authorised user combined with a verification code. When the authorized user applies their fingerprint to the portable access device, the verification code is returned which allows verification of the user. If the access device then receives a key actuated device identifier matching one in storage, the associated access key is retrieved and transmitted to the key actuated device to allow access to the user.
