New iPhone case turns phone into mobile wallet

In the near future, customers may be able to use their iPhones as credit cards.

According toMobile, DeviceFidelity has built an iPhone case that will enable an iPhone itself to be used as a form of payment. Customers would be able to leave purses and wallets at home, carrying only their iPhone, and make purchases.

While similar devices are commonly used in Japan, DeviceFidelity's website will run trials in the second quarter of 2010 for North American usage.
