Everyone's probably heard of RFID it's commonly used in supermarket product identification, security door pass keys and keeping tabs on school kids in Texas.
Has anyone tried a USB RFID reader on the PI or does such a thing exist at all??
Something like the Adafruit PN532 breakout board (http://www.adafruit.com/products/364) together with some kind of USB cable (FTDI USB TTL RS232 cable)?
That device is intended for NFC use, which is typically 4 inches or less. For typical RFID tags, like those used in many consumer products, you would probably be better of with this: http://www.parallax.com/tabid/768/Produ ... fault.aspx
