Abstract
A key for accessing an electronic lock that also has an optical scanner includes a user interface, first and second memories and a shared data transfer circuit. The first memory serves to store access data detailing identities of locks accessed by the key. The second memory stores data scanned by the scanner. The access data and the scanned data can both be downloaded from the key via the shared data transfer circuit.
