EMV (Chip and PIN) offers a functionality called iCVV which prevents cross contamination attacks. Visa and MasterCard must enforce the EMV liability shift in all regions, especially the US, such that operators of non-compliant devices carry the fraud risk.

The Banks made a cynical decision to introduce 20 year old technology with Chip and Pin to avoid obligations. It is no wonder that such a primative system has been surped by criminals. But that is what happens when you 'go cheap' on security. How about a Fingerprint reader coupled with the chip

Barry Purkis, Havant, England

The first thing I thought when they bought in chip-and-pin was how easy it was going to make it for fraudsters. Now, rather than only using my PIN at a trusted ATM, I have to use it on numerous unverifiable devices, which also read my card! I'm quite suprised it took so long for this to happen.

Card readers being stolen from stores? Why doesn't anyone think outside of the box these days.
I've been sent a card reader from my bank for online transactions. I suppose all I need to do is pull it apart in the comfort of my own home and see how it works.
Me and thousands of other customers!!!!!

Whatever the system, dishonest people will find a way around it. There's nothing wrong with sound technology - the problem is with people who abuse it. Crime doesn't pay.

"This crime will not be tolerated" -but there is no deterrent! Prisons have to be made into places where no one wants to be-put the prisoners into chain gangs and make them work extremely hard, to pay back society for their wrong doings. No TVs, no telephones, definitely no computers and games, hard

Chris, S'bury,

We never had a fraud problem with our accounts UNTIL Chip n Pin came in. Now we've been 'done' twice to the tune of 1000 quid. The first time an Asian guy living in central Moscow used my card for goods bought in USA. I wonder why nobody sussed it wasn't me??!!

Why not make the devices self-destruct when opened? A small vial of liquid to be punctured when the cover is opened rendering the device useless will prevent them from being tampered with. Presumably the device handshakes with the card when it's presented - such data elements could be made transientso that when the device is unplugged it becomes useless with a master set of reactivation codes.

Simes, Sevenoaks,

There is a contact less pre-paid card that just started in Dundee which would beat this. You top it up at home then you don't have to worry about theives getting to your bank account, as they don't touch your bank card. It is really easy and a lot of shops are getting into it.
