If my friends comes to know my credit card number, what can happen -

If somebody gets to know my credit card number only(without expiry date, name of owner) - can he/she use my credit card fraudulently on online transaction?


Often many merchant/mail order companies ask for credit card details (number,expiry date, name, date of birth etc.) over phone.

How safe it is to tell these info over phone? What is the guarantee that they won't misuse this information?

Any help is welcome.
