Regardless of what has been said above, perhaps everyone needs to consider that card fraud is often via highly organised channels.
As an example, I read recently about one of the UK's largest retailers ( I think maybe Tesco?), being associated with card fraud. Essentially, it happened via the chip and pin devices that are on the end of each till. It turned out a number of these devices had been supplied new from the manufacturer with a data logging system and mobile phone system built in. This then in turn relayed all card data and pin numbers back to an overseas gang.
Obviously the retailer, although involved, had no idea what was going on.
So, even if there is an issue, (and I do say IF), it may not be that simple
