As cyberwarfare threat looms, cashless Nordic nations go back to banknotes | Miranda Bryant

Nordic countries were early adopters of digital payments. Now, electronic banking is seen as a potential threat to national security

In 2018 a former deputy governor of Sweden's central bank predicted that by 2025 the country would probably be cashless.

Seven years on, that prediction has turned out to be pretty much true. Just one in 10 purchases are made with cash, and card is the most common form of payment, followed by the Swedish mobile payment system Swish, launched by six banks in 2012 and now ubiquitous. Other mobile phone payment services are also growing quickly.
