I'm aware that they've had the Chip and PIN technology on the other side of the pond for a while now, but what I need to know is; do our new chip and pin system cards work in America so I can use it or do I still need to sign for purchases whilst I'm in the States?
I have never been asked for my PIN on Mastercard purchases in the US, in fact they very rarely even check the signature.
It is usually a case of handing the card over, it is swiped, then - as soon as the card is authorised - the cashier hands the card back and you are then asked to sign after the slip has printed.
