German bank Landesbank Berlin will trial mobile payments using microSD cards and a contactless attachment for the iPhone, the bank announced today.
Update (Jan 5): The bank said it will issue the microSDs supporting a Visa payWave application, which a limited number of employees of the bank and Visa Europe-Germany employees will be able to tap for purchases of up to €25 (US$32.42) without PIN or signature. End update. There is an option in the iPhone app that would require the customer to enter a password on the phone before each payment.
The trial will use microSDs and contactless iPhone cases or sleeves made by U.S.-based DeviceFidelity. The cases, called iCaisse, contain a contactless antenna and chip and microSD card slot.
