I’ve found in the past Germans aren’t always keen on credit cards - they often push back when you try to use them in shops and restaurants and things like ticket machines at railways only seem to take regional debit cards. Trying to use an American Express gets a very bad reaction. Is that changing?
German here; MasterCard and Visa are accepted almost everywhere even the smallest shop usually offers contactless payments (tap). Amex on the other hand is a rarity and you should expect that it doesn’t work.
For reading the comments it seems like people are exited about the Apple Card solving a set of problem I simply don't see most people having here in Denmark.
