We recently hear a lot about NFC. This feature is available in the latest high end smart phones present in the market. NFC stands for Near Field Communication. NFC is a protocol designed for smart phones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. This type of communication is needed for simple and fast data exchange between devices.
And for engineers and hobbyists it is another important communication method. And for establishing this NFC communication we can use this PN532 MODULE. This module acts a modem to send and receive data.
PN532 is NFC RFID (Radio Frequency Identification) module. This module is built around NXP PN532 IC. NXP PN532 IC is very popular in NFC applications.
