Epay - Frequently Asked Questions (FAQ)

General payments

  1. What kinds of cards are accepted?
    Only MasterCards/Eurocards and VISA cards.
  2. May all MasterCards/EuroCards and VISA cards be used?
    Unfortunately, all MaserCards (and some Corporate VISA cards) issued in the Americas (including the USA) will be rejected because MasterCard/VISA do not provide a payment guarantee for payments made with these cards.
  3. What is a CVC2 code?
    The CVC2 security code is a verification number printed on the back on your card near the signature. The code is the last three digits of the shown seven-digit number. Its purpose is to increase the security of online purchases and must be entered in addition to the card number and the expiry date.
  4. What is 3-D Secure, Verified by Visa and MasterCard SecureCode?
    The 3-D Secure protocol is a security system developed by VISA to improve the security on the Internet. Its purpose is to fully authenticate cardholders during an online purchase, reducing the risk of abuse. VISA and MasterCard have their own implementations of this system, known as Verified by VISA and MasterCard SecureCode respectively. As a consequence of these security systems, some customers may be asked to enter a security code provided by the issuer in addition to the card number and expiry date in order to fulfill a payment.
  5. Why am I asked to enter a security code associated to my personal bank?
    This is a part of the 3-D Secure system mentioned above. Which security control that is used for this type of system will depend on the issuer and type of card. Some customers do not have to enter a security code at all, while others may be required to enter a code used for Internet banking applications, such as on-time passwords or a code generated by a password calculator.
  6. I am trying to pay with my card, but I am always getting an error telling me that my card number etc. is invalid.
    Please verify that you have entered all 16 digits of your card, a valid expiry date and CVC2 code (the last three digits of the shown seven-digit number near the signature) correctly. If you are still getting problems, please try again after a while.
