Of course huge amounts of stores offer contactless paying, but generally Cash is still dominant around here. Change is slow, and currently, Cash is still king, especially with small or street merchants.
For many small businesses non-tax registered money is the lub which makes them run well.
Jokes aside the price of getting a card terminal where for many businesses completely unattractive for a long time and often still are if put in context to the number of people which will use it.
I know one local takeaway which stopped accepting card payment after their terminal broke recently, as it wasn't worth it to buy a new one. Instead they now allow sending money by PayPal, but non-advertised and mainly for a single specific big recurring customer and sometimes if someone doesn't has cash with them.
Smaller stores or restaurants, forget it. Bring cash.
