Isis will roll out its mobile wallet application nationwide later this year following successful pilots that launched last fall in Austin, Texas, and Salt Lake City, Utah.
Isis, which competes with Google Wallet and other mobile wallet technologies, relies on Near Field Communication technology that's now offered in 35 smartphone models sold by AT&T, T-Mobile US and Verizon Wireless, the company said in a statement.
Isis is a joint venture of the three carriers.
The Samsung Galaxy S III and S4 and the HTC One X support Isis currently, among others.
The iPhone, Windows Phone and BlackBerry 10 devices are expected to start supporting Isis mobile wallet later this year, Isis said.
Isis said that since its pilots began last October, the number of retailers and other locations that set up NFC readers for contactless payment has quadrupled to more than 4,000 locations.
Active Isis users tap their mobile wallets more than 10 times a month. The number of users was not revealed, however.
Isis provided testimonials from Coca-Cola and Jamba Juice about the success of the pilot programs. Coca-Cola North America Group said more than one-third of active Isis mobile wallet users in Austin loaded a My Coke Rewards card onto their wallet.
Jamba Juice said Isis drove incremental foot traffic to its stores.
A major factor limiting the acceptance of NFC-abled mobile wallets has been a shortage of NFC-reader payment terminals in stores. Isis now says that 25 of the top 100 national retailers have deployed or are deploying contactless terminals. Aite Group estimated 1.3 million locations nationwide will have such terminals by the end of the year.
