I believe even here it will change. Before that, stores had to take cash (like in Germany) and now they are allowed not to in certain cases and e.g. in Reffen the streetfood stands do not take cash at all, but you can exchange cash for some kind of debit card. Retail in Denmark does not particularly like to take cash and you can see a lot of signs about "no cash stored after closing" and empty register drawers etc. in Copenhagen. I would expect lots of these stores to switch to cash-only as soon as they can. Such a law happened in Sweden already and you just need to go to Malmö C to see stores not accepting cash at all.
