You can pay online (almost) anywhere where the merchant accepts a Mastercard.
As we are licensed by the National Bank of Belgium, there are certain categories of merchants for which we are not allowed to accept transactions. If this is the case, you will receive a push notification in the app that a transaction is not allowed at that type of merchant.
Contact us through our support channels if our system would not allow a payment at a very well-known merchant (e.g. Amazon).
