Fingerprint Door Lock - This advanced lock only opens the door when both fingerprint identification and a password are used according to the user’s settings, to enhance home security. The product also adopts state of the art Random Security Coding technology which generates two variable digits, and after pressing these two digits, a user can enter his/her own password and will not expose the password on the touch pad.
Arguably best tattoo story I ever heard - my buddy's dad was a Port Authority Officer at the Twin Towers on 9/11. Went into one of them to find a stairwell full of people trapped behind a locked door, janitor next to it dead. Picks up the janitor's key ring (with 100's of keys) and the first one he picks out opens the door.
