Wei-Meng Lee has an RFID review / tutorial in this month’s CODE magazine called Fun With RFID. The Phidget RFID reader was reviewed and used as part of the article. The online preview of the article doesn’t get to the part with Phidgets RFID reader, but you can check out the article and buy the magazine if you are interested 
Code Magazine & Wei-Meng sent over the actual article as a PDF for us to provide to our readers. That was very nice of them. They also provided this discounted subscription link for people interested in getting the magazine.
