Isis has confirmed that they are launching the service on October 22nd. And just like before, it shall launch in Austin and Salt Lake City for now. They also claim “as many as” 20 smartphones will support Isis, but the older devices might be left out. A bit sad, I always hoped my aging AT&T Galaxy S II will get Isis, since it has an NFC chip. Though the fact that you need a special SIM card might offer some hope, as it might have the NFC secure element inside. Let’s hope more locations start supporting Isis. Are you excited for this mobile payment system? Tell us in the comments!
