Info - Card Verification Value
For security reasons it is necessary to fill in the Card verification value of your
credit card.
For credit cards of VISA / EURO-MASTER the number can be found on the rear, in the signature field,
following the printed replica of the credit card number embossed on the front of the plastic.
The value is only printed and is not contained in the magnetic-stripe date.
In the case of American Express cards the number is a 4-digit value and is to be found
half way down the right-hand in the front of the card.
