I don't know how fast the adoption curve will be for that. Until there is one hardware and software standard, mobile payment is going to have it's challenges. Many merchants want to do their own mobile payments platform. Merchants also have to purchase a special NFC terminal to participate. Everyone is eventually going to be financially motivated to do EMV so that will become ubiquitous. Also, the price will come down. I think a lot of folks would pay $25 to have a card that eliminated all their CC#'s or MC or VISA buys that startup out.
