I was at Radio Shack the other day and came across a nice little gem. This RFID reader is selling on clearance for $8, when it normally goes for $40. It comes with two tags. The ones I got are a credit card sized version, and a disc version. I couldn’t resist, so I bought it and spent 20 minutes getting it working with my Arduino Decimilia (yes, yes, I know it’s outdated). Be warned, these are only sold in stores and are on clearance, so call your local Radio Shack before stopping by to pick one up. You can buy the more expensive ones at the Parallax web store. You can buy Arduinos in many places, including Amazon.
