RFID Reader For Your iPhone
Benjamin Blundell built a hardware interface for his jailbroken iPhone that reads RFID signals. By patching in his homebrew hardware to his iPhone via a standard iPhone USB cable the reader detects low-frequency tags and will soon be able to read MIFARE tags as well.
You can bet you will never see this app approved in the official Apple app store, but just imagine how cool it would be to read RFID tags with your iPhone. Check out the video after the break
