    For the past 3000 years, when people thought of money, they thought of cash. From buying food to paying bills, day-to-day dealings involved paper or metal money. Over the past decade, however, digital payments have taken off—tapping your credit card on a machine or having the QR Code (二维码) on your smart phone scanned has become normal. Now this revolution is about to turn cash into an endangered species in some rich countries. That will make the economy more efficient, but it also brings new problems.

Countries are getting rid of cash at different speeds. In Sweden the number of retail cash transactions (交易) per person has fallen by 80% in the past ten years. Cash accounts for just 6% of purchases by value in Norway. Britain is probably four or six years behind it. America is perhaps a decade behind. Outside the rich world, cash is still king. However, in China, digital payments rose from 4% of all payments in 2012 to 34% in 2017.

Cash is dying out because of two forces. One is demand—younger consumers want to enjoy their digital lives with payment systems. But equally important, suppliers such as banks and tech firms are developing fast, easy-to-use payment technologies from which they can pull data and pocket fees.

In general, the future of a cashless economy is excellent news. When cash payments disappear, people and shops are less likely to be stolen. Besides, digitalisation greatly expands the playground of small businesses by enabling them to sell beyond their borders. It also creates a credit history, helping consumers borrow. Yet it is not without problems. Electronic payment systems may suffer technical failures, power blackouts and cyber-attacks. What’s more, in a cashless economy the poor, the elderly and country folk may be left behind.
