Introduction
Near Field Communication (NFC) is a set of short-range wireless technologies. It's behind daily applications
such as access control system and mobile payment system.
Grove NFC features a highly integrated transceiver module PN532 which handles contactless
communication at 13.56MHz. You can read and write a 13.56MHz tag with this module or implement point
to point data exchange with two NFCs. Grove NFC is designed to use I2C or UART communication protocols,
and UART is the default mode. In addition, we assign an independent PCB antenna which can easily stretch
out
