The fingerprint reader add-on case is compatible with the PinePhone and the PinePhone Pro. It uses pogo pins located on the smartphone’s midsection and attaches by replacing the default back cover. It uses a fast and high quality fingerprint sensor capable of accepting swipe input (up/down and left/right). Gestures could potentially be used for scrolling or UI navigation. The i2c bridge between the phone and sensor uses an open firmware written by Zachary Schroeder.
The case is built very sturdy out of black, thick and polished plastic. The back case is built in a modular way and the electronics are easy to replace. This isn’t only good from a repairability perspective but also makes it easy to mod the existing functionality or hack in a new one.
