Pocket-sized OV-Chipkaart reverse engineering

For those interested in reverse engineering the OV-Chipkaart system (aka Dutch public transport card that’s currently being hacked to shreds because of gross incompetence of Trans Link Systems); here’s an setup that’ll work and fit in your pocket :)

Just a Pandora with a common RFID reader. With the proper knowledge you can whip up your own within a few hours ;)

Also fun would be to replace the reader with a custom Bluetooth capable setup (the Pandora already has Bluetooth). To help you on your way I’ll leave you with these URL’s: an ISO 14443 RFID module combined with a Bluetooth serial bridge. Put it in a lunchbox or something innocent looking and they’ll never suspect a thing.
