Detailed Product Description:

Unlock secure and efficient contactless communication in your embedded systems with the versatile RC522 RFID 13.56MHZ Reader Writer Module. Powered by the NXP MFRC522 chip, this highly integrated reader/writer IC is your go-to solution for implementing RFID-based access control, attendance systems, inventory management, and other smart applications. Operating at the global standard 13.56MHz frequency, the module is fully compliant with ISO 14443A/MIFARE protocols, enabling seamless interaction with a wide range of common RFID cards and key fobs.

The RC522 RFID module primarily communicates with microcontrollers like Arduino via the SPI interface, offering high-speed data transfer rates of up to 10 Mbit/s, crucial for rapid tag reading and writing operations. It can also support I2C and UART communication, providing design flexibility. Its integrated analog circuitry efficiently demodulates and decodes responses from passive transponders, while internal buffers and a CRC coprocessor ensure data integrity. The typical operating voltage range is 2.5V to 3.3V, but importantly, its communication pins are 5V tolerant, allowing direct connection to 5V microcontrollers like Arduino Uno without the need for additional logic level converters.

When you buy RC522 RFID module kits in India, they often include a standard S50 blank card and a key fob, allowing for immediate prototyping. The module's compact design and built-in antenna make integration into various projects straightforward. Its read/write distance typically ranges from 2-5 cm, depending on the tag and environmental conditions. For those seeking reliable performance at an accessible RC522 price, this module is an excellent choice for a wide array of RFID security projects and NFC module 13.56MHz applications where a robust and budget-friendly solution is required.

The RC522 RFID Module is a high-frequency (13.56 MHz) RFID reader/writer module that uses the MFRC522 chip to communicate via the SPI interface. It's ideal for projects requiring contactless authentication, such as door locks, time attendance systems, or ID verification.

Compact, efficient, and cost-effective, it supports ISO/IEC 14443 Type A cards (including MIFARE). The module operates with 3.3V logic, and it is widely compatible with platforms like Arduino, ESP8266, Raspberry Pi, and STM32.

This module comes bundled with a MIFARE 1KB RFID card and key fob, making it a plug-and-play solution for your RFID-based projects.
