[Benjamin Blundell] built an RFID reader for the iPhone. A jailbroken iPhone connects to this project box by patching into a standard iPhone USB cable. Like in past iPhone serial projects, [Benjamin] is using openFrameworks for the software interface. Right now this reader only detects low-frequency tags but he’s working on the code to read MIFARE tags as well. See the magic of a tag ID displayed on the screen in the video after the break.
