On March 29 local time, the Bank of England, the Bank of England, issued an announcement to remind people to replace the paper currency with a new version of plastic currency with a face value of £ 20 and £ 50 as soon as possible. After September 30, 2022, shops and other businesses are not allowed to trade in paper sterling, but UK bank customers can still deposit paper money into their accounts.

A portrait of the British mathematician Turing is painted on the new 50 pound note in memory of the father of computer science and artificial intelligence.

The Bank of England said the new plastic banknotes are more wear-resistant and more difficult to counterfeit. In 2017 and 2018, the UK has stopped the circulation of £ 5 and £ 10 banknotes respectively. According to statistics, there are about 17 billion pounds of paper money in circulation in the UK market.
