South Korea
The Bank of Korea, South Korea’s central bank, has plans to go cashless as soon as 2020, and adopt a national digital currency comparable to bitcoin. The plan is to phase out cash in steps, for example by having merchants give change to customers in the form of electronic credit, rather than in cash. The nation was one of the earliest to adopt virtual currency, in the form of video-game–based credits that took on the role of cash. In January 2010, the nation’s supreme court made the landmark decision that gaming currency was to be recognized as convertible to cash.
Sweden
The first country in Europe ever to issue official banknotes (in 1661) could be the first in the world to stop using them. Currently, you can’t buy subway or bus passes with cash in Sweden. According to the Riksbank, the Swedish central bank, only 20% of all store purchases in 2015 were made with cash. How did this happen? According to the Riksbank, it’s due to a few factors: 1) a sparse population makes the distribution of physical currency relatively inefficient and costly; 2) there are only a few banks, making it easier for them to cooperate on streamlining payment systems; and 3) the society is tech-friendly.
