Support Stocard Pay Card?

Was trying to add my Stocard Virtual Card to Curve and got a message that it does not support it yet(!) despite being a mastercard.

Not all MasterCards can be added to Curve, most prepaid MasterCards can not be added. Is the StoCard Virtual Card a prepaid card? If so you can fill out a form to request the possibility to add the card to Curve. Form can be found on the support page below:
