Chinese Banks Use UV Light To Disinfect Banknotes

"China is disinfecting and isolating used banknotes as part of efforts to stop the spread of the coronavirus that has killed more than 1,500 people, officials have said.

Banks use ultraviolet light or high temperatures to disinfect yuan bills, then seal and store the cash for seven to 14 days – depending on the severity of the outbreak in a particular region – before recirculating them, China’s central bank said at a press conference.

The virus, which has infected more than 66,000 people in China and spread to more than two dozen other countries, has sparked a rush to disinfect public places and minimise contact between people."


UV light (or UV-C light, to be more specific) has been scientifically proven to effectively kill bacteria, viruses & other pathogens.

It is also a clean & non-chemical approach to disinfection, which probably explains why it was one of the chosen methods by Chinese banks to disinfect their banknotes during the coronavirus crisis.

Some of the obvious benefits of using UV-C light to disinfect bank notes are that it is a clean & non-chemical approach to disinfection, coupled with the fact that UV-C light does not require the introduction of any moisture to the bank notes (which are presumably not very water-resistant).
