Decoding the MetroCard, Part 2: Research and Past Attempts

Interesting read, but somewhat disappointing. I expected something like a demonstration of a card reader dumping the contents of the card, and an Arduino-controlled magstripe spoofing it. Excellent writeup nonetheless!

I actually have dumped MetroCards using a reader, but I'm saving that for a third post ;)

I take it that if you figure out you can write a stripe that overflows the scanner firmware in a way that unlocks the gate you won't post it until you're done using it...

If you're asking whether I'd exploit it, the answer is a firm no. I'm not the biggest fan of the MTA (nobody who lives in NYC for any substantial amount of time is), but the personal benefit would be minuscule compared to the consequences.

More to the point, making a public display of weaknesses in the MetroCard might finally get the MTA off their ass and onto that modernization project they've been promising for the last 15 years ;)
