Isis, the coalition of US wireless carriers AT&T, Verizon and T-Mobile to bring NFC payments on handsets to the masses, will not go forward as planned earlier, according to reports on Wednesday. While trials were due to start early in 2012, the three carriers have now purportedly agreed to change their approach and make it less advanced. Instead, they will create a "mobile wallet" that will link users' existing Visa, MasterCard or other major credit cards to the account, though this is not official yet.
