Isis saw its user adoption growth rate double last month and is now adding an average of 20,000 new users a day, Michael Abbott, CEO of the US carrier-led NFC venture, has revealed.

ABBOTT: ‘Response has been tremendous,’ says Isis CEO

“Since our launch nationwide last November, consumers across the country are experiencing the power and simplicity of paying with their phone and the response has been tremendous,” Abbott says.

“Over the last 30 days, we have averaged more than 20,000 Isis Wallet activations a day and our growth rate doubled over the prior month.”

“As of today, 68 mobile devices across AT&T, T-Mobile and Verizon Wireless support the Wallet,” Abbott adds. “The Wallet now comes preloaded on 14 smartphones with more preloaded devices in the pipeline.

“Our merchant and issuer partners are also experiencing strong results as they offer their customers a new way to pay, coupled with great offers.”

At Jamba Juice, where Isis users get a free smoothie every time they ‘tap to pay’, “Isis represents a growing percentage of our total transactions nationwide, and our stores have experienced more than 50 percent month-over-month growth in Wallet use,” CEO James D White says.

“By the end of the first quarter, Jamba Juice customers had redeemed more than 270,000 free smoothies and we expect to hit one million by this fall. The success of the One Million Free Smoothie Campaign has created habituation among our customers.”
