RC522 Mini RFID Reader Writer Module I2C IIC Interface IC Card RF Sensor Module

Colour: Black Material: metal + plastic 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 compatible with "three-table" applications. Developed compatible with 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. The MFRC522 supports the IC series of higher speed contactless communication with bidirectional data rates up to 424 kbit/s. As a member of the 13.56MHz high-integration read-write card, 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 host, which helps to reduce wiring, reduce PCB board size and reduce cost. 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. Compatible with 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 host through simple lines of the SPI interface, which can support stable operation of the module and long reading distance; the module is highly integrated and small in size. Features help customers to quickly apply contactless cards to the system.
