NFC or Near Field Communication is a technology standard based on Radio Frequency Identification, transmitting information wirelessly over short distances. The key distinction between RFID and NFC lies in their transmission ranges. The RFID is often used over longer distances. NFC, however, only has a maximum range of a few centimeters, at most. NFC devices can act as either a reader or tag. In this tutorial, we will be interfacing PN532 NFC RFID Module with Arduino. Earlier we used the RC522 module which is certainly the best-known RFID module for the Arduino projects. But t
