I apologize for posting this link, since by following it you'll probably waste way more time than you should. Still, life would not be complete without a trip to dognoses.com! Trust me. ":^)

While we are nosing around this subject here's an outfit which provides dognose identification kits (think fingerprints...but cold and wet): Dognose ID.

Or you can get the high tech microchip pet ids. Have you seen Mobile speedpasses or those easy-pay toll smart tags? Same technology is used for the pet ids. They can be put practically anywhere. In fact they could (or have!) put one inside of you. It's called RFID technology. It's a very small circuit which obtains power wirelessly from the device trying to read it. The earliest versions simply had some form of unique ID that was sent out whenever a reading device was close enough to provide power. Newer ones can accumulate information and even perform limited processing. You can pick up a complete eval kit for about 0 and make your own home monitoring system.
