As others have said, VZW along with ATT are working on their own product, which judging by the length of time it is taking to come to market, is probably going to be underwhelming. In preparation for their own subpar product, they block Google Wallet, which makes me wonder how this isn't anti-competitive.
I'll have to finally look and see if there is anywhere I can even use it. If so, maybe I'll put it on the S3.
