I was going to purchase some photographic goods from a German online computer/photo supplier (computeruniverse.net) and was in the process of giving my credit card details when I was requested to photocopy both sides of my credit card and fax it together with my personal details to a German fax number. The reason given was that, in Germany, they can't verify cards the same way as in other countries so they need a copy of the signature on the card. They said that this would be a one-off as the details would be held for future purchases. I didn't feel comfortable with this and backed out.
Can anyone please tell me if I am being over-cautious or is this actually the case in Germany? I haven't dealt with this company before - their website looks good and they seem to have a huge range but that means nothing these days.
Thanks!
