I am currently in Florida where I have tried using four different cards (3 Credit cards and a Debit card). When I use them for transactions requiring a signature, there is no problem. However, when trying to use them for Chip and PIN transactions I always get a "Not Authorized" response. I have tried five different retailers, each with more than one of my cards and have never yet succeeded. I am definitely using the correct PIN (the one that works fine in the UK). I have emailed the card companies for help but have only got unhelpful, asinine replies. Has anyone else had this problem and resolved it?
