This tutorial was developed for the MAKE course at the University of South Florida (www.makecourse.com). This tutorial discusses the use of a MF522-AN RFID reader and MIFARE Classic 1k tags/cards with the Arduino. The basics of RFID communication are reviewed as well as the MIFARE card hardware. A library for the MF522 that can be found at github (https://github.com/miguelbalboa/rfid) is being used for a simple Arduino sketch that allows the writing and reading of blocks on a MIFARE card.
