Over the past few months I have been asked by businesses over the phone to give out the following credit card information.

Card number.
Expiry Date.
Name.
3 digit security number.

I have declined each time and said I was very uncomfortable giving out all this info especially the 3 digit number over the phone. They seemed very surprised so I wonder how much this is now going on.

Am I correct in the assumption that once a person has all this info they could go to any website and order what they please? I cannot think of anything else they need that would stop them placing orders. I will keep saying no but wonder when it will start becoming a problem and the card manufacturers have to come up with another new security measure.
