By Bams Sadewo October 18, 2012 53 29 30 2 The marketing head of Isis, Jaymee Johnson, has sent out a statement to tech publications across the country that its mobile payment service will indeed be officially rolled out on October 22. Come Monday next week, folks in Salt Lake City and Austin who are keen on leaving their wallet at home when out shopping, will be able to tap and pay their way out of Isis-ready stores.Advertisement Of course, there are some obstacles to pass before one can wave their phones to purchase things. As previously reported, the service dictates users to use a special ISIS SIM card, which they can get from each carrier. They also have to download the Isis Mobile Wallet app from Google Play. Not helping to the matter is the fact that Isis is only compatible to run on a limited number of handsets. To be specific, only one device – the Droid Incredible 4G LTE — supports Isis on Verizon for now, while you can use Isis on three T-Mobile smartphones – the Samsung Galaxy S3, Samsung Galaxy S2, and Samsung Galaxy Relay 4G. As for AT&T, the carrier has announced that the Samsung Galaxy S3, Samsung Exhilarate, Samsung Rugby Pro, LG Escape, and HTC One X will all support Isis on launch day. The joint venture between the three major U.S. wireless carriers is hoping to have 20 Isis-compatible handsets ready by the end of the year, the details of which will be shared on October 22. 53 29 30 previous postNewman N2 is a $240 Galaxy S3 alternative with quad-core CPU, 13 MP cam and 720p screennext postOppo Find 5 shines in first leaked images, HTC beware!
