My Target card has a PIN. My major credit cards with big limits have a PIN. Don't confuse PIN with the mag stripe. It's two factor identification.
1. Something you know: the PIN
2. Something you have: the card with the chip in it that is not easily forged or reproduced.
The fingerprint is the third of the three types of "factors" to authenticate you. Try as hard as you like, there are only three ways to authenticate something:
1. Something you know. (password, pin, musical notes, etc)
2. Something you have. (car key, house key, credit card with built in microprocessor and storage, a key fob device with USB connector, etc)
3. Something you are. (fingerprint, retina scan, DNA, etc.)
The fingerprint just allows the possibility of three factor authentication. There are no other ways other than something you know, you have, or you are.
BTW, that chip on the credit card is a tamper proof self contained computer with storage. (also: it runs Java.) It has a private key that was originally generated on the chip and never leaves the chip. The bank has the other key of that key pair. So the bank can be sure you really do have the actual card when the card is inserted into the POS terminal. The card can authenticate itself by signing a random token from the bank, while the card is inserted in the terminal. Only your card could do that because nothing else has that private key to do the signing.
The credit card has always been "something you have". It's just been a question of how easy is it for a crook to replicate that card and have it too. The new chip makes that cost prohibitively high.
