Near Field Communication (NFC) is a set of short-range wireless
technologies. It is 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 of any enclosure you use, leaving more room for you to
design the exterior of your project.
