Mobile commerce joint venture company Isis, created by AT&T Mobility, T-Mobile USA and Verizon Wireless, has launched a promotion offering Wells Fargo credit card holders the potential for 20% back and a $20 statement credit the first time they tap to pay using the Isis Mobile Wallet at hundreds of thousands of retail locations in the US. Now through 30 April 2014, consumers using a participating Wells Fargo credit card in the Isis Mobile Wallet will receive a $20 credit applied to their statement the first time they tap to pay, along with an additional 20% back in statement credits on all tap and pay purchases, up to $100 in statement credits per calendar month. In December, Wells Fargo and Isis announced the first phase of an agreement that allows Wells Fargo Visa consumer credit card holders to load their cards into the Isis Mobile Wallet. The 20/20 promotion announced today is available to all Wells Fargo credit card holders who add participating credit cards into their Isis Mobile Wallet. The Isis Mobile Wallet is supported on more than fifty Isis Ready smartphones available on AT&T, T-Mobile and Verizon Wireless. Once consumers have an Isis Ready smartphone, they can get an enhanced SIM card from their carrier and download the Isis Mobile Wallet for free from Google Play.
