I actually rely on this self destruction, I have a scrap of paper in my wallet with "Pin Numbers" written on it along with 3 random four digit numbers, gives me minor peace of mind that if my wallet is lost and found by someone that wants to try and use them, hopefully they'll lose them to an atm rather than using them online.

I like that idea.

Unfortunately it doesn't prevent them using them online as well. At least for my cards, if I lock out the PIN I can still use them for non-PIN purchases.

Ah, in the UK it is standard for the machine to keep your card after three incorrect pin attempts. (at least I think it's the standard?)

I'm in the UK as well. I was actually thinking of Chip & PIN transactions, but you may be right about cash points.

Good point. wasn't thinking about that.

Awesome idea :)
