Master Pro with card system "Money A"

Hello together,
have the following problem, we have a Solis Master Pro with card system in our workshop, now unfortunately I run out of cards and the manufacturer does not follow this system anymore. In other words, I can't get any more replacement cards, I've contacted a card manufacturer about this, but he said that there is a key/code on the cards that makes it impossible for him to produce replacement cards for me.
But since I don't want to give up this system so easily, I'll now turn to you. Does any of you still have spare cards or the code that is on the cards? Maybe also a contact who could help me in this matter?
would be really great if someone could help me.
Many thanks to you

Have you checked with Schaerer or WMF? They have the same system.
