Just noticed the other day,the "chip" on my chip and pin bank card has fallen out of its hole in the card,still got it, it popped back in,has anybody else had this problem? and what would happen if someone got hold of the chip? can any info be got from it?
It does seem to be a bad design,the card is fairly new.

with the right card reader you should be able to get all the data off it - however you would need to have the algorithm to de-code it - but I'm sure if you search around on the net you can get it...

have you taken it back to the bank yet... what did they say?

Someone I know has also had this problem. Someone could potentially use it fraudulently but you'd have been very unlucky indeed for that to happen.
Ring your bank and ask for a new one. You may have difficulty using the card in the meantime - banks will honour payments to the retailers taken via the "swipe" but retailers aren't obliged to accept any particular form of payment from customers and so are within their rights to decline non-chip cards.

or in this case, they could just attach the detached chip to a genuine card and have a few stabs at the pin - no need to decode what's actually on it!
Still, deano has his chip safe and sound so should be OK.

Gonna nip into my bank this week and order a new one,i suppose if it was lost i would have to be very unlucky for someone to find it and know what it came from.
Still seems like a bad design though,thought they would be more secure.

Maybe a bad batch, I have 3 cards with these on and have had them for ages with no problems.

I have found that the card shows signs of usage before the chip strip.

because banks are that stupid.

do a search on encryption factorisation prime numbers 128 bit.

See if you can come up with a way to crack it (if you can i think there's a million dollar prize available). PS - the crack has to be feasible in the lifetime of this universe and not based on non-existant quantum computing devices.

That's a fairly negative, narrow view. Because of course DVD encryption can't be broken. Neither can the Enigma code.

my view is negative?

Do you think that chip + pin encryption is based on the mathematically flawed CSS algorythm, or on enigma coding (this isn't even encryption, but is encoding).

Chip+Pin has to be as secure as it's possible to make it, so they use tried and tested industry standard private/public key encryption.
If anyone can hack it, they've have gone and claimed the $1 million prize, and mathematics as we know it would have undergone some fairly serious convulsions.

The key difference with DVD's is that everyone who had a DVD player had the key to unlock it sitting around anyway, they just needed a way to get to that key. If you can hack into a banks internal systems and find the key then you could easily decode the information on a chip.
