• Whitelist every Creditcard payment to a daily/weekly maximum.

I have trouble with Flight Bookings, since there is often changing websites to book. But every site needs a whitelisting. So payments fail normally at first try. At second try the sites increase price already sometimes up to 20%.


I need a free amount on the card, that gets allowed at any case at the first payment try. If some is malicious, a blacklist will help.

    Hi Falk! 🙂


    Thank you for your suggestion!

    We value security and love to keep our users save. We want to keep your money safe! This is why we don't allow a free amount that gets allowed no matter what.

    In your case there might be a work around: Make sure that if a payment fails, you open the page in a different browser, this should prevent a price increase.

    I wish you a great day!

      This is not only for flight bookings, but also for indie games/apps. I also have issues with merchants that change their name slightly but because the name is changed I have to re-approve.


      I understand the security part but not the usability part. I have to again go through the payment flow of the merchant.


      Why not let a real-time approval (push notification) be possible that the creditcard step has to wait on your approval. With a timeout of 10s (nice architectural challenge).


      Or that you can set a limit for a first time transaction at an unknown merchant for a month? So that they can only do this once during a month?

      I understand that if I get 10 faulty approvals a day this can get costly but your systems can be triggered by these kind of patterns, right?


      Hope you find a better way than the current (duplicate) way.

        I agree. I love the MasterCard for bunq, and also the attention for security. But these small things are already making me consider an alternative.


        Isn't it possible to do something with 3D Secure and the QR code like iDeal? For payments that don't do 3D Secure, a chargeback option should be available, as those merchants already decided they want to take on chargeback risk in return for the better customer experience.
