The Parallax RFID reader is a pretty cool bit of tech. For $40 you get a reader with integrated antenna that outputs ASCII at 2400bps. Unfortunately, the integrated antenna means you can’t place RFID tag sensing in tight spaces. You can however circumvent the built-in antenna and add your own. With a remote antenna of your own creation, you can customize its size and shape to fit your application.
