Mobile Phone Operated Lock
-
Published in issue 345, July 2005
The main ideas behind the lock described here are minimum obtrusiveness and minimum user interface. A typical code lock is operated with a four-digit secret code and the lock can be opened by presenting this code. The lock described here has no buttons or keypad at all, a small hole or other hiding place for the microphone capsule is enough.
