Motorola DROID RAZR HD and the Motorola DROID RAZR MAXX HD to the compatible list this week while at T-Mobile, the Samsung Galaxy S III, Samsung Galaxy S Relay 4G, and Samsung Galaxy S II will support Isis. Over at AT&T, the Samsung Galaxy S III, HTC One X, Samsung Exhilarate, LG Escape and Samsung Galaxy Rugby Pro are all Isis-enabled. The banks currently working with the service are American Express, Capital One, and Chase. If you have a credit card from one of those issuers, you will be able to use Isis.
As with any debut for something of this ilk, Isis is starting off small and will eventually add more locations and more banks. Now we will have to see if this becomes a wake up call for Google. And yes, don't forget that Sprint is also working on its own mobile payment service. A list of locations that accept the service can be found here.
"MasterCard has been working with industry partners like Isis to turn mobile phones into secure payment devices and create better shopping experiences for both consumers and merchants. The use of NFC technology is a path to an improved consumer experience, and the launch of the Isis Mobile Wallet – combined with the growing number of NFC-enabled handsets – will help make mobile commerce a reality for millions of consumers."- Mung Ki Woo, group executive, mobile, MasterCard Worldwide
