This kit includes a 13.56 MHz RF reader/writer module built on the integrated MFRC522 chip, together with two S50 RFID cards. It is a low-voltage, low-cost, compact contactless card chip solution, suitable for smart meters and portable handheld devices.
It supports ISO14443A frames and error detection, and it can read MIFARE S50, S70, Ultralight, Pro and DESFire cards, with two-way data transmission up to 424 kbit/s and support for the CRYPTO1 encryption algorithm used by secured MIFARE cards.
Operating current is 13 to 26 mA at 3.3 V DC, and the operating temperature range is -20 to 80 C. Reading distance is at least 50 mm, the module measures 40 x 60 mm, and the maximum data transfer rate is 10 Mbit/s. The interface is SPI.
The package includes the RFID-RC522 module, a blank RFID card, a special-shaped card (a key ring fob), a set of straight pins and a set of curved pins. Wire the SPI pins plus a reset and interrupt line if you need it, install an MFRC522 library and run the example that reads a card's UID.
Makers building access control, attendance systems and card-based projects on Arduino and similar boards.
Wire the SPI pins (SDA/SS, SCK, MOSI, MISO) plus RST and 3.3V power, taking care not to accidentally power the module at 5V, since the RC522 is a 3.3V part. After installing a library such as MFRC522, run the UID read example first, and note down the card and fob's IDs so you can compare them in your own access-control logic.
