Is there any vendor that offers RFID tags relatively cheap (and in decent quantities) along with a software development kit? I've tried to search around a bit, but specifically what I am looking for are small, low-range tags that I can use/track/experiment with...the idea is to build things that will interact with my PC/Windows.
they have a lot of good resources!
VeriSign also has an evaluation kit that makes use of their EPC test network. It comes with a test tag andf some software but I think you have to buy your own reader.
