Description
Features: 13.56Mhz, S50, Mifare One
RC522 IC Brief Introduction
MF RC522 is used in highly integrated 13.56MHz contactless communication card chip to read and write, of NXP for “three” and the application launched a low voltage, low cost, small size, non-contact card chip to read and write, intelligent instruments and portable handheld devices developed better.
The MF RC522 use of advanced modulation and demodulation concept completely integrated in the 13.56MHz all kinds of passive contactless communication methods and protocols. 14443A compatible transponder signal. The digital part handles the the ISO14443A frames and error detection. In addition, support Quick CRYPTO1 encryption algorithm, the term verification MIFARE series. MFRC522 support MIFARE series of high-speed non-contact communication, two-way data transfer rates up to 424kbit / s.
As 13.56MHz highly integrated card reader series chip new family, the MF RC522 MF RC500 MF RC530 there are many similarities, but also have many of the characteristics and differences. Communication between it and the host SPI mode, helps to reduce the connection, reduce PCB board volume and reduce costs.
RFID Module Brief Introduction
MF522-AN module uses Philips MFRC522 original chip design circuit card reader, easy to use, low cost, suitable for equipment development, the development of advanced applications reader users, the need for RF card terminal design / production users. This module can be directly loaded into the variety of reader molds.Module uses voltage of 3.3V, simple few lines through the SPI interface directly with any user CPU board is connected to the communication module can guarantee stable and reliable work, reader distance.

Works great with this library: https://github.com/miguelbalboa/rfid

Great reader.
easy to experiment
Christoph (verified owner) –
Very good reader, works better than many that are sold in door locks and has greater range.

Actually, the board is fine, but MFRC522 itself is an unnecessarily cumbersome chip.
Didn’t work with the miguelbalboa code for me, but did work fine with Eelco R’s simpler code: http://forum.43oh.com/topic/4028-energia-library-nfc-card-reading-with-energia-mf-rc-522/).
Ever wondered why the IRQ pin is not connected? Me too. IRQ handling would imply the antenna always on, which means a power consumption in the 10-20mA with NO card (measured), so actually a “halt – wait 300ms – check tag” polling cycle works much better power-wise, than a more logical IRQ-driven approach…
Tolerates low SPI speeds (tried with100+ kBaud).
Range: 1.5cm with the key tag, and 3cm with the card.

BTW, tested OK with Raspberry Pi B+ (Python) and MSP430G2553 (both Eneriga and barefoot).
An OK product, “nice for the price”, but I’d only buy one again because I’ve put so much time into it by now (that reached “point of no return” with the non-recurring engineering cost 😉 ).

Can I use UART? because the datasheet wrote the UART feature
Chao (store manager) –
No, the uart pin did not lead out, can only use SPI.
su –
can i use this kit without connected to a pc after i program it? or does it always have to be connected to pc to work?
poulbran –
lost of uses like bunker door or magic games.
Used it in a school project once

Excellent product and good price

Running mine with Arduino Uno and the MFRC522 library. Runs great. Detection range is about 3-4CM for the cards and a little less for the keychain tag.
