SIM cards and NFC chips may work together to provide mobile payment services
Deploying a universal mobile payment system might have a lot to do with the SIM card that resides inside our phones, as it turns out. The GSMA announced today that 45 of the world's largest wireless carriers are in favor of a SIM-based NFC solution, and have committed to support and implement related products and services.

Among the bunch of supporters of SIM-based NFC are AT&T, Verizon, and T-Mobile, which have been working together on bringing a mobile payment system to the U.S. market for quite a while now. As a matter of fact, the three carriers announced the Isis mobile payment venture a year ago and are planning on running live tests of the system as soon as next year. China Mobile and China Unicom, the two of which provide service to about 800 million users throughout China, are also on the list.

So, how might your phone's SIM card and its NFC chip work together to handle mobile payments? It is quite simple actually. All your information, or at least all that is required for a payment to be conducted, will be stored on the SIM card and the NFC chip will be able to read it. In contrast, Google Wallet, which has been live for several months now, does not access your credentials from a physical device and works independently from the wireless carrier.

Here is a part of the GSMA announcement listing of all carriers that are backing up the SIM-based NFC solution:
