Abstract: A Near Field Communication (NFC) apparatus comprises a main printed circuit board and tamper printed circuit board. On the top side of the main printed circuit board are a secure memory element that stores secure applications and secure data, a secure microcontroller that contains firmware for communicating with an external HOST device, and an NFC reader chip. On the bottom side of the main printed circuit board are multiple tamper connection pads and a HOST connector for electrically connecting the main printed circuit board to the external HOST device.
