Guess what, you’re going to be able to add more cards to your virtual wallet. ISIS has said that their new Mobile Wallet Platform, which launches later this year, has expanded to support three more American Express cards. Consumers will be able to use their virtual wallet to shop; all they need to do is use an NFC-enabled smartphone. ISIS will be partnering with AT&T, T-Mobile, and Verizon when they launch in their two pilot cities: Austin and Salt Lake City. [Source: The Verge]
