Wit a master card, there is the option to set the daily limit to “0,00 euros”. Instead of disallowing transactions on the card, this actually disables the limit completely. That’s a bit confusing.
I have a separate online card (great feature!) that I use for more sketchy webshops and I set a daily limit of 1 euro (when I’m not using it to buy something). Would be nice to have a real “0,00 euros” daily limit (without blocking the card).
So my suggestion: make the “0,00 euros” daily limit actually be a “0,00 euros” limit and add a separate entry “no limit”.
