After initial card confirmation (CVV/CVC, etc), there will be an extra step, which will depend solely on how your bank confirms such transactions.

It can be a bank page with a code confirmation, which will be sent to your mobile phone, or banking app confirmation. Some banks provide password cards for example.

Yes, it is due to new EU regulations regarding online payments (Strong Customer Authentication) coming in effect on 14 of September.

The change is being made for debit and credit cards to abide with latest EU legislation. Authentication process depends from your Bank.

It doesn't affect the way other payment methods, like PayPal or Paysafecard, works.

Yes, debit and credit card payments are handled by a third-party payment provider. 3-D Secure is part of the payment process between this provider and your Bank.

It's up to your bank to decide if they'll send you a verification code via sms, or via a pigeon :D

You should contact your bank for more details.

This new authentication protocol is for debit and credit cards issued by Banks only.

Paysafecard is neither - it's a different payment method with its own flow.

I suggest you check that with the bank that issues such cards. New authentication protocols vary depending on the banks, not storefronts.

As far as I can tell, all your recent transactions were declined by your bank after the 3DS check. Perhaps the bank will now let you make another payment, now that they have verified your intention to do so?
The original payment attempts cannot be re-processed though, so the only way to go forward would be to try again.
If it doesn't work, I would suggest contacting your bank in order to check what the underlying issue was, or using a different payment method altogether.

If you wish to investigate further, please open a support ticket - it will be easier than via the forums.

Also, I initially misunderstood the payment statuses and processed your order manually. Once I realized my mistake, I canceled the order. Sorry about the confusion. :(
It's worth checking if there are any regional restrictions imposed on the prepaid cards.
From experience, I know this is often a problem for customers hailing from the USA - oftentimes their prepaid cards can only be used in the USA and Canada.
Might not be the case for EU countries making transactions from other EU countries, but worth checking, just in case.
Dang, 2nd. :(
Thanks, though. :)
