Isis is joined by payment heavyweights

Although earlier in the year the future of Isis, a joint contactless mobile payments venture by At&T, T-Mobile and Verizon, was uncertain. The announcement this week that American Express, Discover, Visa and Mastercard would all accept payments made via the system, has made it seem a lot more assured. The service is due to go live early next year and the announcement gives it the edge over Google Wallet, currently only compatible with Mastercard.
