RFID Module 13.56 MHz Card Reader MFRC522 Reader/Writer Board Only

The RFID Module 13.56 MHz Card Reader MFRC522 Reader/Writer Board Only is a compact contactless RFID reader/writer module based on the NXP MFRC522 IC. It operates at 13.56MHz and is designed for communication with compatible ISO/IEC 14443A, MIFARE, and NTAG contactless cards and tags. The module provides a convenient interface between an RFID system and a microcontroller or development board for identification, access control, attendance, and other contactless applications.

Where to use the RC522 RFID Module

The RC522 is an RF Module that consists of an RFID reader, an RFID card, and a key chain. The module operates 13.56MHz which is an industrial (ISM) band and hence can be used without any license problem. The module operates at 3.3V typically and hence commonly used in 3.3V designs.  It is normally used in applications where a certain person/object has to be identified with a unique ID.

The keychain has 1kB memory in it which can be used to store unique data. The RC522 reader module can both read and write data into these memory elements. The reader can read data only from passive tags that operate on 13.56MHz.

How to use the RC522 RFID Module

The RC522 has an operating voltage between 2.5V to 3.3V and hence is normally powered by 3.3V and should be used with 3.3V communication lines. However, the communication pins of this module are 5V tolerant and hence it can be used with 5V microcontrollers also like Arduino without any additional hardware. The module supports SPI, IIC, and UART communication but out of these SPI is often used since it is fasted with a maximum data rate of 10Mbps.

Since in application, most of the time reader module will be waiting for the tag to come into proximity. The Reader can be put into power-down mode to save power in battery-operated applications. This can be achieved by using the IRQ pin on the module. The minimum current consumed by the module during power-down mode will be 10uA only. The module can be easily used with Arduino because of its readily available RC522 RFID Arduino library from Miguel Balboa.
