1. A lock comprising:
- a lock body;
a lock mechanism actuable between a locked and an unlocked condition comprising a shackle that is movable relative to the lock body between a closed position corresponding to the locked condition in which the shackle is fixed in position with respect to the lock body and an open position corresponding to the unlocked condition in which the shackle is moveable with respect to the lock body;
a lock sensor that is configured to sense actuation of the lock mechanism and to send a trigger signal indicative of actuation of the lock mechanism; and
an actuation identifier generator in signal communication with the lock sensor that generates an actuation identifier in response to the trigger signal.
