MPP

Overview

MPP (Microsoft Pen Protocol) is pen tech invented by Microsoft. We believe this is also very similar to AES.

Originally Microsoft used a tech called N-TRIG in their Microsoft Surface devices, but switched to MPP.

It is still used in many Microsoft Surface devices and a few other mobile products.
