This instructable connects the popular BlueSmirf Bluetooth module to the ID12 RFID reader and shows how to make a dust and water resistant (IP55) RFID reader that sends IDs to your PC or mobile phone over Bluetooth radio without an additional micro controller and without an external power source. Created as a prototype for an online swim lap counter system named Rfish, it can be used for any project in need of a self contained, weather proof RFID reader.
