valid for all products (posters, pdf, subscription)
By entering your credit card CSC, you make sure that your credit card is present as you order online and your data (e.g. from a receipt) is not misused.
The CSC is a 3-4 digit code that is not part of the information printed on receipts (such as name, date of expiration and card number).
That is why the CSC is not stored in our system but has to be entered for every order.
The CSC on your VISA, MasterCard, Diners Club and JCB card is on the backside of your card. It is the last three digits of the number in the signature field.
