Package Included: 1* RC522 13.56Mhz RFID Read Module

It is the communication between the host and the serial communication using fewer connections, and can be based on different user needs to select one mode SPI, I2C or serial UART (similar to RS232). Low-voltage, low-cost, small size and non-contact chip card reader is a good choice for smart meters and portable handheld devices developed. MFRC522 is applied to 13.56MHz contactless card reader communication chips a member of the high level of integration. RC522 RFID Reader Serial 13.56mhz IC Card MFRC522 RF Module.
