Project 44 – Simple RFID Reader
The pins on the ID12 readers are non-standard spacing so they will not fit into a breadboard. You will need to obtain a breakout board from a supplier such as Sparkfun. The cards or tags can be purchased from all kinds of sources and are very cheap; I got a bag of small keyfob style tags on eBay for a few dollars. Make sure the tag or card is of 125KHz technology, otherwise it will not work with this reader.
