We are getting our first glimpse of Isis, the mobile wallet app that will be available to more than 100 million United State Credit Card holders this summer. The new app will compete with Google Wallet and Opera, offering a secure and convenient way to pay with your credit card on your mobile phone.

The UI looks simple enough, with a list of your current payment options (Chase, Capitol One, and Barclay were the first to sign up for the service). Along the bottom we have “Isis Feed” (most likely a payment history page), “Directory” (a list of shopping outlets that will accept the Isis payment system), and “More” (settings).

The NFC-based mobile payment system was created by Verizon, T-mobile and AT&T to try and make mobile payments a common practice.

Verizon came under fire late last year when it was discovered that Google Wallet was not supported on their version of the Galaxy Nexus phone. Critics claimed it was intentionally blocked to prevent customers from using Verizon’s soon-to-be competitor.

Isis will go live this summer, starting in Salt Lake City, UT and Austin, TX as a test run, then nationwide access soon after.
