Norway already has the BankAxept system in wide use. It is mainly used with debit cards though, as far as I know, not credit cards. The fees for using BankAxept are lower than Visa/Mastercard for the merchants, and most debit cards from Norwegian banks have a combination of Visa/Mastercard and BankAxept functionality included. Most merchant terminals are set up to prefer the latter tech, falling back to Visa/MC if the card isn’t BankAxept equipped.

So some of the tech is already there.
