The most common problem with correct on line payment in Croatia is correct 3D verification. Especially with users who normally pay with cards, but in foreign web shops, it often happens that they do not know which information they need to enter. Additional payment autentification has been needed in Cratia for payments via Mastercard, VISA and Mastercard. Some older isuued cards will be soon in 3D secure system. To proceed with online payment , we kindly as users to contact their bank (card provider) by calling the help desk or if a form for entering a 3D secure password appears, yu can find out by clicking on "?" in the 3D intreface. If you think that your problem is different, please feel free to contact us by e-mail: firstname.lastname@example.org. You will recive an answer as soon as possible.
