Our Project aims to enable RFID communication of WUSTL ID cards and Dorm Key Cards. We will use an Attiny85 micro controller to drive a motor driver. The motor driver will output the RFID signals to an inductor. The inductor should acts as an amplifier to the RFID signal that will be readable by a magnetic cars swiper. The Attiny85 will hold up to 4 cards and should have an indicator light for what card is currently in use. The Attiny85 will be programmed using an Arudino Microcontoller.
