Delivered webinar

Session Description

As innovation and market leader for contactless technology, NXP offers a wide range of NFC reader ICs for physical access systems, POS and mPOS terminals, PC solutions, e-Government applications, public transport schemes, Pay TV solutions, eMetering, gaming, industrial, white goods applications and many more.

In these two technical webinars we will provide the insights and skills to design and build an NFC reader. We will review its main components, how to choose the right reader and microcontroller ICs and the proper architecture for your application with respect to security requirements. We will explain the NFC antenna theorical fundamentals, its crucial role in the overall system performance, and how to match it in our NFC reader design.
