An amazingly simple and fun device. They go well with XBee radios to create wireless RFID readers.

Quick note: Even though it is not immediately clear in the datasheet, you DO need a pull-up resistor on the data pins even in ASCII mode.

These are the real deal, complete, self contained modules, a cinch to use at an unbeatable price. Also, based on my tests, these are fully compatible with EM4100 tags, not just EM4001 which was an older, now obsolete standard.

A great device, at a good price. I managed to get it on a breadboard, although the 2mm pin spacing presented a bit of a challenge.

The ID-12 easily detected all 4 of the RFID cards I tried, my indicator LED flashing as each card was read.

Next, I interfaced the ID-12 to my PC through a serial connection, and used Windows Hyperterminal to display the incoming ASCII data.

The ID-12 performed perfectly, and I highly recommend it.

Anybody want to comment on what kind of range they are getting. I'm using a small 21mm circular tag and only getting a range of about 12mm when i was hoping for what the specs say 12cm.

What about those 10.56MHz cards they have at TI, any modules out there for those?

sorry i meant to say 13.56MHz

Does anyone know what temperature range the ID-12 can handle?

My comments:
- connect D0 to pin 5-yellow of a TTL-232R USB cable and use 'screen /dev/ttyUSB0' (or similar) to see output (you can also use the 5V provided by pin 3-red)
- no pull-up needed on D0
- pins required some bending and shoving to get it to fit in a breadboard - use the breakout board and headers

Is it possible to hook up a self build antenna to this RFID module?

Hi, I see that you do not have this component, you'll get it again? when?
Do you have a delivery to Croatia?
