This breakout module brings its SPI interface to a 0.1\"-pitch header compatible with Arduino, ESP32, Raspberry Pi, and virtually every other development board. Includes one Mifare 1K RFID card and one key fob, both pre-programmed with blank user memory.\u003c\/p\u003e\u003cp\u003eThe RC522 reads and writes Mifare Classic, Mifare Ultralight, NTAG203, and most ISO 14443A cards at 13.56MHz — the same frequency as building access cards, transit passes, and NFC-enabled smartphones. Excellent starting hardware for RFID cloning research, access control prototyping, and learning about contactless protocols.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eChip: NXP MFRC522\u003c\/li\u003e\n\u003cli\u003eFrequency: 13.56MHz\u003c\/li\u003e\n\u003cli\u003eSupported cards: Mifare Classic 1K\/4K, Ultralight, NTAG203, ISO 14443A\u003c\/li\u003e\n\u003cli\u003eInterface: SPI (up to 10MHz) or I²C\u003c\/li\u003e\n\u003cli\u003eOperating voltage: 3.3V (5V tolerant SPI lines)\u003c\/li\u003e\n\u003cli\u003eRead range: approximately 5cm with included antenna\u003c\/li\u003e\n\u003cli\u003eIncludes: module + 1× Mifare 1K card + 1× key fob\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Golden Physics Project","offers":[{"title":"Default Title","offer_id":54186580377892,"sku":"GPP-RFID-RC522","price":14.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2879\/9524\/files\/RC522-RFID-module.jpg?v=1780943169","url":"https:\/\/shop.goldenphysics.org\/products\/rfid-rc522-module-13-56mhz-nfc-rfid-reader-writer-for-arduino","provider":"Golden Physics Project","version":"1.0","type":"link"}
