1) the token used as coin for the lock should be different from the normal coins used as currency
2) in order to open the locker with such lock, the user only needs to insert the coin to the slot on the lock and turn the knob directly without using any key, which is different from the traditional coin lock that requires a key to open the lock after inserting the token.
3) user does not have the permission to lock the locker back after they open it, which means they cannot turn the knob back to lock the locker and get the token back after opening the lock.
4) a master key should be provided to administrator, who can use the master key to reset the locks and get the token back.
