SparkFun will be closed Nov 26th and 27th for the Thanksgiving holiday. Orders placed after 2:00pm MT on the 25th will ship out Monday the 30th.
Description: RFID (radio-frequency identification) is the wireless non-contact use of radio-frequency electromagnetic fields, for the purposes of identifying and tracking tags attached to objects. This is the ID-12LA, a very simple to use RFID reader module from ID Innovations. With a built in antenna, the only holdup is the 2mm pin spacing. Power the module, hold up a 125kHz card, and get a serial string output containing the unique ID of the card.
Note: The new ID-12LA is essentially the same as the ID-12, but has a lower voltage input.

I use ID-12LAs as part of my model railroad to track rolling stock as it leaves and enters yards. The ID-12LA plays an integral part in generating “Wheel Reports” that are used by Yard Masters to route cars during “Operating Sessions” which simulate the operations of real railroads. We’ve found the ID-12LA to have the optimum range for reliably reading “kitty tags” on the bottoms of railroad cars without getting false reads from cars on adjacent tracks. Also the ID-12LAs can placed as close as 6" from one another without interference which is great for busy yards with multiple throats.
We’ve even offered the RFID system to other model railroaders using the ID-12LA from Sparkfun: visit us at http://www.modelrailroadcontrolsystems.com/radio-frequency-identification/ for more information!
Sparkfun provides great support and carries all the handy bits you need to make your project come to life!
The RFID worked like champ. I was disappointed that the breakout board did not come with the product.
Used these with a dual reader shield attached to a Arduino uno to read chips attached to HO train cars. Highly recommend the extra break out board to attach them to the reader shield. Found out I can use a few more since the rest of the hardware I already have will support 8 reader chips instead of the original 4 I had planned for.
