I am currently living & working in the USA and as such, I have credit cards with "chip & signature" security.
When I use one of these cards, I either insert it into the chip-reader in the merchant's card terminal, or if they haven't yet begun accepting chip cards I swipe my card through the old magnetic strip reader.
I then may, or may not, be asked to provide a signature using the "pen" on the terminal's touch-screen.
But I will soon be traveling internationally to countries where "chip & pin" is the standard form of credit card security - and many merchants in those countries have credit card terminals which have neither magnetic strip readers nor "pens" to sign on the screen.
Do I need a pin code associated with my credit cards in order to be able to use them in these countries?
Will my transactions just be authorized with no pin or signature?
