Wanted to bring this to the front. I think Citibank is the largest issuer of card with PayPass and/or PayPass payment tags for the key chain now.
I am port of a mobile trial in NEw York, where we have PayPass in our cell phones. (I was given a Nokia prototype for 3 months to test it out.)

It is so convenient -- no signing and no wallet involved for both the phone with PayPass and payment tags.
Any one use PayPass or blink from Chase?
