We are now carrying this popular RFID Mifare card/tag reader/writer. This module can be directly loaded into the various reader molds, very convenient. It is very easy to use as there are tones of library and examples, especially using Arduino. It is based on the MF522-AN module and ready with the RFID antenna built in. MFRC522 are similar to MFRC500 or MFRC530 , but also have the characteristics and differences. Communication between it and the host SPI mode helps to reduce the connection narrow PCB board volume, reduce costs.

MFRC522 supports MIFARE series of high-speed non-contact communication, two-way data transmission rate up to 424kbit/s. It supports rapid CRYPTO1 encryption algorithm, terminology validation MIFARE products. The digital part of to handle the ISO14443A frames and error detection. 14443A compatible transponder signals.

The MFRC522 use of advanced modulation and demodulation concept completely integrated in all types of 13.56MHz passive contactless communication methods and protocols MFRC522 is applied to the highly integrated read and write 13.56MHz contactless communication card chip. Low-voltage, low-cost, small size of the non-contact card chip to read and write Smart meters and portable handheld devices developed better choice.

Is the uid writeable for these cards?
This is necessary for cloning...
( Vijayendra Olety , 16/07/2020 )
Hi, we're sorry as it is not writeable. Thanks :)
HI CAn this be applicable to PI3 b+ and PI4 B?
( charleston retuya , 05/06/2020 )
Hi, yes they are compatible. Thanks :)
The pin already soldered or not? If not, can I request to be soldered? Thanks. ( Naqif, 27/04/2019 )
