"There are already cards with biometric technology out there, so instead of a signature or familiar swipe, don't be surprised if your next credit card asks you for a thumbprint."

This would be more secure in some ways, but I'm reminded of an incident mentioned in another thread where a man was drugged and his fingerprint was used to access his phone.

I got a new debit card a couple months back that is vertical like that. Got a few weird looks from cashiers when I use it.
