Ooh! Somehow I thought you meant credit card. No, indeed, normal cards are normal cards. Misunderstanding is entirely on my side

Side note, but you can say you have a debit card, then pay with a credit card and usually it will go through. Or vise versa. No idea why they make the distinction, maybe the fees are different but the cashier usually can’t tell.

I think there's some confusion here, you can use a credit card and have it processed on the back-end as a debit transaction, for a consumer the distinction is almost unnoticed.

This differs greatly according to global region. Germany from what I've observed is an outlying for noticing the distinction (mostly because they suffered from very high credit card surcharges for decades vs the rest of the world).
