We all know about RFID, the technology that retailers say will allow them to better track their goods and keep people from shoplifting, that medical professionals say will allow entire medical histories to be kept on keychains, and that the government is using to validate our passports. RFID is even being used to store credit card information in some cases, making checkout at stores and gas stations easier and quicker. Depending on where you stand, RFID is a horrible tool that will allow malicious minds to learn everything about you or the best thing since sliced bread. The truth? Probably somewhere in the middle. But there's no better way to develop your opinion than learning about the technology, right?

The RFID Experimentation Kit from ThinkGeek hopes to help everyone learn a bit about the contentious technology, and maybe sooth a few fears while firing up a few more. The kit comes with a USB RFID reader that can read the tags from up to 4 inches away, and software to get you off the ground and the book RFID Toys that contains several RFID projects you can try with the kit; like making your own RFID door lock, (not unlike the MyKey RFID Door Lock) using RFID to log in to your computer, making an RFID safe, and more. The kit also includes several cards, keychains, tags, and adhesives that are ready to be programmed for whatever project you choose. Be warned, the software and RFID reader are easy to use, but for some of the more technical and in depth projects, you'll have to get your hands a little dirty.

Among the tags included are super-small pill RFID tags and card tags, and all of the tags come pre-coded with information, so they're read only-no putting your medical history on it and implanting it into your arm, for example. And while it's not at all recommended, I suppose you could pair a lock to one of the tags and then implant it into your arm, but I think it would be easier to just pair one of the cards to a lock and keep the card in your wallet. Besides, the tags aren't sterilized. The RFID Experimentation Kit is available now for $99.99.
