Isis, the mobile payment venture backed by AT&T, T-Mobile, and Verizon Wireless, will launch nationwide later this year.
The service uses NFC and allows smartphone owners to make tap-and-go payments at participating retailers. The service has been undergoing trials in Austin and Salt Lake City since last year. It was due to launch earlier this year, but faced delays.
According to Isis, 25 of the top 100 retailers are installing terminals compatible with the system. Many consumers already own smartphones with the necessary NFC components inside.
