Thanks to DCist – http://tinyurl.com/5spogg – I got inspired to rip apart an extra SmarTrip card I had lying around for when friends/family visit me in the D.C. area. Unfortunately for them, they will now have to buy the day-long pass until I am done playing!
To start, today I took the extra card and soaked it in acetone for about an hour and after that time I was able to rip off the initial plastic of the card. After that hour-long of soaking you’ll find the card becomes very flexible and if you attack the corners with tweezers you’ll eventually realize the 3 layers of the card. The face of each side should peel off rather easily, although a minute amount of force is required.

If you take a look at the images you’ll see that all of the electronics (controller, antenna) are now exposed and we can start to play. My girlfriend just handed me a Faraday flashlight with a GIANT coil of magnet wire inside of it, so now we’re working on extracting that wire to use as the antenna for the smarTrip’s microcontroller.
More to come…
