Call the Thumbsmith!

My friend Rigpa had some funny comments about fingerprint locks:

I was just thinking why thumb fingerprint key access will never catch on:


The building maintenance guy will have to carry arround a large keychain full of thumbs.

Ask the gas station attendant for the key to the bathroom. You get a thumb attached to some large object (a tire rim?) so no one will steal it.

It's hard to drive a car having to keep a thumb in the ignition key.

It's difficult to get a duplicate thumb.

Passer-bys will wonder why you are displaying your key, when all you really want is to thumb a ride.

You will have to trim the thumbnails on your keychain to keep it from getting too bulky.

If you spend too long out in the pool and your fingers get pruney? you'd have to call a thumbsmith to get back into your house
