Arthur Maestro and VPay are international standards.
There are not as international as many people might believe. True, the "Deutsch"-speaking countries (DE, AT, CH, LU, NL, please forgive me for including you here) have always been a hotbed for issuance of Maestro and V Pay - foregoing Mastercard and VISA debit, which can also be used if card is not present. But that's what they're largely confined to, nowadays. Many European countries' banks do not even regularly issue Maestro and/or V Pay - or they've stopped a while ago (French, British or Spanish Maestro or V Pay cards, anyone?). And until very recently, V Pay card acceptance was confined to Europe as well, with cards refusing to work outside of Europe.
So they are somewhat "multi-country international", but far from "globally international".
And ultimately, even though Maestro/V Pay might be favored in more than one country, the effect is pretty much the same as with local schemes: Maestro cards work at (virtually) every Mastercard terminal within Europe. But many people's "normal" debit card (provided as standard with their European bank account) is not accepted in the Netherlands.
