New ATM card contains a chip which suffered an 'accident'. Will card work in ATM?

I think the Black Helicopters have whisked H_TeXMeX_H away.

Also, it turns out the protocol is crappy so criminals can use stolen cards without knowing the PIN or copying any data from card.

Chip and Pin is broken

The problem is that the terminal isn't validating the PIN against anything it can trust... it's sending the entered PIN to the card and trusting the result returned, which can easily be spoofed. If the PIN was server-side, it could trust a results-only message... but that's not what's happening here.

But the scam is a lot like those used with regular meg stripe cards: A fake reader glued to the ATM / gas pump.

They did, and they kept me in a small room, and beat me and gave me all sorts of injections, and then beat me some more. I had to eat mostly rats and lick moisture that condensed on the walls of the cell. I managed to escape through a vent, and I'm back

Anyway, I guess GrapefruiTgirl was talking about a smart card and not an RFID, so if it breaks some functionality may be lost.

So, I'm curious about the fatal "accident" that disabled the chip. Was it the H_TeXMeX_H solution, or did it get gnawed by a rabbit?

Heh. I accidentally jammed my fingernail into the chip indentation a bunch of times, from each side of the card. I could hear stuff crunching, I think it was little tiny wires snapping. Soon after, the external contact pads began delaminating off of the card. :-}

2600 had a great write up on disabling the RFID chip inside the banks atm/debit card. I believe it involved a hand held hole punch. I don't remember what issue that article was in off the top of my head, but it was as recent as the past 18 months.
