The Isis mobile payment system, Google Wallet’s competitor, was finally launched on October 22 after numerous delays. We’re not surprised if you haven’t heard much about its impact, since the new system is currently only available in two cities for AT&T, T-Mobile and Verizon Wireless subscribers.

Being one of the biggest proponents of Isis, so much so that it blocks the use of Google Wallet on its devices, Verizon strangely only has a handful of smartphones that support it.

As of last week, the list consists only of HTC’s Droid Incredible 4G LTE. Joining the roster now are two smartphones from Motorola, the Droid Razr HD and Droid Razr Maxx HD.

Although the devices above already come with a built-in NFC chip, those who want to try out the new craze of tapping their smartphone to pay for things must also get a special NFC SIM card to run the Isis Mobile Wallet app. You can get more details about the supposed future of payment system from our post here.

Anyone planning to give Isis a go? Or is Google Wallet more than suffice in meeting all your mobile payment needs?
