If you mean reset the card, no, not that I know of. There’s probably some esoteric method of hacking the card, but that wasn’t my goal. I was just interested in the privacy aspect of any tracking data it might contain. I just read it according to the manufacturer’s instructions.

If you just want to detect the password-fail error, you can follow the instructions in this tutorial. Look at the first four bytes to see how many retries remain.

The cards are designed to self-destruct if the wrong code is entered three times in a row. Maybe this happened.

I say we need to subject these chips to Van de Graaf output arcs, preferably arcs from a generator at least 4 feet tall. Remember, you were TOLD these chips were going to be implemented, you were not ASKED if you wanted them.

Interesting read. I toyed with Atmel CryptoMemory used for some laundry cards last summer, and the datasheet for those also provided the default passcode (which the vendor didn’t change). I hoped these might be the same, but from the datasheet:

“As shipped, the PSC is programmed with a code according to individual agreement with the customer. Thus, knowledge of this code is indispensable to alter data.”

So no luck on that front. Impressive work, in any event, though! :)

If you a datasheet for it, you can probably interface it with the Bus Pirate.

Can you read the newewst smartcards with NAGRAVISION system? =]

If they are still using the default code for writing process, that’s problem.

@vivi: Kinko’s probably hasn’t changed anything. I used to work for the company for about a year and a half. They liked to spend money, but never on the right things. This probably wasn’t one of their main concerns. Especially since not a great deal of people know about it or how to do it.

The Metro Smartrip card is RFID. Nobody’s hacked it. It’s a stored value card.

@vivi: They’ve switched to the SLE5542 and the silicon is now mounted face down, but I’m not sure what changes Kinko’s has made to their system.

@Elwood: this is not an attempt to hack the card, just read the contents. SLE4442 datasheets detailing the protocol are available from various manufacturers.

I wonder if they fixed their cards since the 2006 hack, though.

@Ghrayfahx: a lot of readers natively support reading SLE4442 cards, check your manual !

This well written article on how to dump the data stored on the card using the recently covered “bus pirate” is not old and it was excellently written! I have been looking for a detailed tutorial such as this, thank you!
