If anyone is using the new chip and in credit cards that are being issued in the uk and elsewhere, or have friends coming form overseas, then beware.

I tried to use mine in Big C today. Thailand, lagging behind the times, has not had the equipment to handle chip and pin and so the cards default to the swipe and sign mode. But, Big C seems to have new euipment that handles chip and pin. Trouble is, nobody has trained the cashier in what to do, so when faced with a request for a pin number she quickly typed in zeroes, without asking me. This happened 3 times, during which she would not stop and listen to me, and of course then the card was declined and blocked, and i can't use it again until i go back to the uk and reset the pin number.
