Overview

This documentation shows how the provided hardware and software components can be utilized to evaluate this use case. The information shall help to understand the OPTIGA™ Authenticate NBT’s pass-through functionality and how it can be utilized in actual applications. This is shown by minimum-viable applications, which allow to control a microcontroller board’s LED from a mobile phone via NFC.
