RFID Mini Module 13.56MHz Read-Write Card Chip MF RC522 HW-868

Description:

MF RC522 is a high-integration read-write card chip used in 13.56MHz contactless communication. A low-voltage, low-cost, small-sized contactless card reader chip for “three-table” applications is a smart meter. And a better for the development of portable handheld devices. The MF RC522 utilizes advanced modulation and demodulation and fully integrates all types of passive contactless communication methods and protocols at 13.56 MHz.

Supports 14443A compatible transponder signals. The digital part handles ISO14443A frame and error detection. In addition, it supports the fast CRYPTO1 encryption algorithm and verifies the IC series of products. The MFRC522 supports the IC series of higher speed contactless communication with bidirectional data rates up to 424 kbit/s.

As a new member of the 13.56MHz high-integration read-write card family, the MF RC522 has many similarities with the MF RC500 and MF RC530, as well as many features and differences. It uses SPI mode for communication with the , which helps to reduce wiring, reduce PCB board size and reduce cost. [Introduction to RFID Module] The MF522-MINI module uses RC522 chip to design the card reader circuit. The module works at 13.56MHz frequency and conforms to ISO14443A standard.Suitable for users of advanced applications such as device development and card reader development, and users who need to design/ RF card terminals.

This module can be directly loaded into reader molds. The module adopts a voltage of 3.3V, and can directly connect with any CPU board of the through several simple lines of the SPI interface, which can stable and operation of the module and long reading distance; the module is easy to use, highly and small in size. Features such as helping customers to and quick apply contactless cards to the system.
