When we provide our credit card information via remote means, we are often made more vulnerable to identity theft by the authentication process itself. If you are unfazed about sending your information via electronic means, consider something similar: paying for a meal with a credit card. I saw my first portable credit card reader on American soil the other day when paying the bill at a new restaurant. The reason those machines are great is simple: The server has no opportunity to write down or photograph your card information. Obviously, the reservations department asked for my credit card number and expiration date.
