By placing an RFID tag inside my wallet I can open my garage door when I get home from work on my bicycle by simply placing my wallet close to an RFID reader that is mounted on the inside of my garage. The reader is made by Parallax and I purchased a few of them for $10 each when RadioShack was closing them out. The reader talks to a microcontroller that validates the tag number and checks to see if the tag is cleared for entry at the current time of day.
