Ask HN: What are the most popular online payment methods in EU countries?

Hi,

I'm making a list of the most popular online payment methods in EU countries among locals (ages 25-45). I'm specifically interested in the 'truly' day-to-day, most convenient, or liked methods.

For example, in Poland, the most commonly used method among my peers would be BLIK. In The Netherlands, it's iDEAL. In Denmark, it's probably Dankort.

I'd love to find out more about all/other EU countries.

Please feel free to share your personal preferences too! The more methods/names, the better for my research. :-)

I appreciate every answer/comment. Thank you.
