Back in March, we reported on Visa’s partnership with DeviceFidelity to bring mobile payments to the average cell phone user using embedded near-field communications (NFC) payment technology into SD cards.

Most recently, the team created In2Pay, a new iPhone case that forgoes some of the complications for phones that do not have SD cards.

Much like many other third-party external battery cases, In2Pay connects through the iPhone’s dock connector, providing a powered interface for the SD card. Once synched with the payment app from Apple’s App Store, the device acts as a reliable mobile credit card for retailers equipped with no-swipe payment capabilities.
