In Denmark "I'll MobilePay you 50 crowns" or "can you MobilePay me 200?", at least when speaking English.
My Danish isn't good enough to reliably say what it is when speaking Danish. Probably something like "Jeg mobilepayer dig halvtres¹ kroner"
The system in Britain (Paym) hasn't really caught on. They might be less keen to verb a noun.
¹ This is why I avoid discussing numbers in Danish.
