I was mildy perturbed to read in the Money section of the Sunday Telegraph yesterday about a Mint (a division of the Royal Bank of Scotchland) cardholder getting uptight with the way his card transaction in a retailer has been handled.
Instead of the price being displayed on his receipt, his PIN was next the £ sign. This happens, apparently, if the card holder keys in his PIN before the retailer keys in the price.
And guess what, it's a rather large loophole in the Chip & PIN system - if the retailer is crooked, then they can extract PINs from cardholders in this way.
Mint didn't score any points in its dealings with the cardholder either, as it ended up having to shell out #30 in compensation for the cardholder having to drive 20 miles to his nearest RBS ATM to change his PIN and ignored all his requests for an explanation - until the paper intervened.
It strikes me that the Chip & PIN system, including the very public PIN entry pads in many stores, is a great idea, but very poorly implemented. APACS has a lot to answer for...
