years ago, when i run a pub
i used to tell customers to never use their credit card anywhere they have to hand it to someone
to prove my point, i would take there card for payment
and in the few seconds of handling their card right in front of them
i would memorize all the details
about 4 pints later i would recite their card details from memory
and then say, "imagine how easy it is if i use pen n paper...."
then i would explain to them about skimmers, which can be worn and unnoticed on a belt
all you need are the details, not the card
hotels, bars, clubs are the worst places to use a card
and never allow others to handle your card
