(More images of ID-12 in the lab here)
I have had the chance to work with the ID-12 RFID reader for a couple of days. It is very small, very cheap and easy to use. I have tested it connected to a arduino microcontroller, to a computer with a usb-serial adapter and wirelessly to a computer with a bluetooth modem.
You can find a code example for maxmsp + schematics on how to hook up the reader here.

The RFID reader is a pretty closed circuit though in terms of how near one must be to make it trigger and its main purpose – checking a particular ID and controlling access.
I wonder what kind of RF reader is in these anti-shoplifting systems, their range is better, probably because of their antenna and they react to something most people carry around at all times – consumer products. How about building a such a reciever and teach it to trigger on a specific type of consumer?
One could build it into whatever, say a brick wall and have the wall scream insults or praises, commenting on the products they have bought…

Oh and I love the little red light on the micon, much cooler than my BS2s.. Does it blink at all?

Well thats what an RFID reader does, read ids of tags, and if they had a range that was too big it would be hard to distinguish individual tags.
The anti-shoplifting system works quite differently I believe, as the tags are just antennas which relate to the frequency of the “portals”, they have no unique id.
the little red light indicates a bluetooth connection on the blueSMiRF, which is just a bluetooth modem, not a microcontroller. For more info check out the resources section

I want to ask
how much its price ?
how you buy it ?
I want to have some “play” with it too 😀

if you click on the ID-12 RFID reader link in the post, you will find where to buy it.

Do you know if the ID-12 RFID reader works with the Arduino BT, because the BT runs at 115200 baud only? Many thanks.

I don´t know, maybe ID-innovations who make the reader can help you? http://www.id-innovations.com/

Hey, I found this board made for the ID-12/20 here: http://www.jayconsystems.com/product_detail.php?prod_id=283
Has anyone ever used it before? It seems intresting.
