RFID tags are all over the place. They're used in building access control systems, passports, inventory tracking. This instructable will show how you can use an Arduino and a few simple components (wire coil, transistor, capacitor, resistor) to make a device that can spoof an 125 KHz (low frequency) RFID tag.
