Dancard works for local payments, but the discussion here is about the growing demand to transact with foreign companies online. For example, if you're in Denmark and you want to buy a SaaS subscription from a US company, you're stuck giving them a Visa/MC number. Some of the downsides of this are the 3% fee, risk of the number being stolen, not to mention Visa/MC applying US law and morals to kill businesses anywhere in the world.
