Paying by credit card is globally considered safe, fast and uncomplicated. This includes payments on the Internet, too. As the cardholder, you enter your credit card number, the appropriate expiry date, and the corresponding card verification number, also known as the CVC or CVV.
This code can be found on the back of your VISA/Mastercard and JCB (3 digits). On American Express cards you can find the verification code on the front (4 digits).
The card verification number is required to secure payments by telephone or transactions on the internet against fraud.
