The following video shows how I used my Raspberry Pi ($35 Mini-computer) to read in data from RFID "Tags"

#Background
===========
So I've always have nerded it up, but now I finally get to merge projects. Thus, I am presenting a Parallax RFID Reader (spec sheet for you fellow engineers) using a RasPi running Arch Linux. I assume you all know this, but in case you were under a rock: The RasPi has the GPIO set of pins on the board. These can be leveraged for all sorts of projects. In my case I noticed the UART Tx and Rx. Serial Port Transmit and Receive, so to speak...

I picked up the reader on clearance at a local Radio Shack for $10. I've been playing with it on my linux machines, via a 2" Rs232 adapter, but I decided tonight to plug it straight into the RasPi. However, as we linux users know it takes a bit more than plugging it in and playing...

#Setup
======
The Project needed a few things:
1) A Linux Distro
2) The Parallax Reader + wiring
3) Programs to capture and view the RFID Reader
