Why fumble around looking for the right key to open the
door?
A 'keyless' lock with a metal contact point. When
touched, it
sends a super-low voltage electric signal through the
finger.
This voltage is picked up by electronics built into a
watch.
The electrical signal contains the lock's
key code. The
watch
has several key codes and unlock data for different locks
that
have been programmed by the owner. The watch then
produces the code response as a low-voltage reply back
through the finger (this all happens in less than a second)
and
the door unlocks. The 'watch' should be able to contain
additional electronics to allow it be used as a timepiece.
Unless the watch itself is stolen, it would be more secure
than the fingerprint locks.
Note: will work with any exposed body part - elbow,
nose, etc...

.....so, it's not "keyless". The key just looks like a watch. |
|
| |
Most of the technology for this is already available. |
|
| |
RFID would work just as well. |
|
| |
Not RFID. This could be used for situations where
you want to open a particular lock in close
quarters.
I am thinking about lockers, automobiles and
other
situations where you don't want to just be near,
you
will want to touch the exact lock you want to
open. |

[Ian], the wrist watch is named after the
watchmen, people who would call out the time in
a town square. The mechanized replacement of
this job was still called a 'watch'. |
|
| |
[8th], the 1-wire technology looks like the protocol,
however this system uses a fob with its own metal
contact. I propose a system that is tuned to
communicate through low-voltage signals along
human skin. |
|

[Ian] No, no, no, the term "wristwatch" derives from early handheld timepieces being novelty items designed to humourously resemble female genitalia; "risible" or "wrisibal" (OE from OHG), giving us "wris-", and "twatish" or "-twatch" from OHG and Flemish roots. |

Unless she were Brazilian. |

Would they keep it in a fanny-pack? |
|

I was thinking about this idea some more, and though it could also be used in factories as secure switches to turn on machinery. The worker is given 'clearance' for certain operations, and others are 'locked out'. Just don't forget your watch at home... |
