Over 30%? I don't know anyone who has ever suffered from Credit Card fraud. Someone tried to transfer money out of my PayPal account once but, as it emailed me to tell me, that got stopped within about five minutes. I genuinely find it difficult to believe one third of all adults have been defrauded using a credit card. Especially given that most elderly people don't trust debit cards - let along credit cards - and so don't posses them.
PS I still find it unbelievable that banks\credit card companies will phone me up and ask ME for my security details (the one exception I've come across being smile). They get a short, sharp response from me when they do!
