> Girokarte is a synonym for Debitkarte
I'm not sure how to handle this because it's both incorrect in technical language (Girocards are exclusive to a particular payment infrastructure that only exists in Germany, unless partnered with a separate payment infrastructure, but the co-branded payment infrastructure is only used outside of Germany [1]) as well as incorrect with respect to my experience with everyday language, including all of the links I've provided including from official government sources.
But I agree on one thing: it's a waste of time to keep talking about this.
As for the rest, I guest we are wasting each other's time discussing this any furher.
