Today we will start to understand how RFID cards work and how they can be used with your Arduino. You will see, which cards and readers are available and how they compare, we read RFID cards from a hotel and a trade show, and we will do some experiments to protect your cards against attacks. And maybe we even clone cards? All legal, or at least, sort of.
