DeviceFidelity, a mobile technology company, announced the availability of its In2Pay solution for iPhone, which enables iPhone users to make contactless Visa transactions by simply waving their iPhone in front of a contactless payment terminal.

In2Pay was originally announced back at Mobile World Congress but final release has been held until now. The solution combines DeviceFidelity’s In2Pay microSD technology with a patent-pending protective case that adds mobile contactless capability and works with iPhone 3GS and iPhone 3G.

By placing a removable In2Pay microSD into the protective case, iPhone users can use In2Pay’s secure contactless capabilities where contactless transactions are offered. Trials are scheduled to start during the second quarter of 2010.

The microSD card and iPhone case work in conjunction with the free In2Pay iphone app, which is available for free at the App Store.

“With our In2Pay solution, we want to give both iPhone users and app developers the power to do even more, by putting the convenience of interactive secure mobile transactions right at their fingertips, anywhere they are,” said Amitaabh Malhotra, COO of DeviceFidelity, in a statement.
