RFID Digital Door Lock
This RFID (radio frequency identification) will make losing your keys a thing of the past. Just tap your RFID card or keyfob to the reader button to activate, authenticate, and unlock your door. If you ever do lose your card or keyfob, just change your PIN and reprogram new RFID cards. No need to change locks.
The RFID lock has a night deadbolt function which disables all external functions, so even if someone did get a hold of your card or key, they still couldn’t get in.
You can buy the RFID Digital Door Lock at ThinkGeek.
