CORONAVIRUS-KILLER COULD LIGHT UP BANKNOTES

Kavan Ratnatunga writes:

"Our banknotes in circulation may never look the same if Far UVC (207-222nm) lighting is put up in public places to curb COVID-19."

Far-UVC kight in occupied public spaces

Kavan included a link to a videoconference with Columbia University scientists examining the possibility of deploying special lighting in public spaces to curb the transmission of diseases such as the coronavirus. It's non-numismatic, but as noted could make banknotes look different since many of them incorporate anti-counterfeiting features that become visible in ultraviolet light. Here's a vivid example from an earlier article on a Canadian Passport UV light light anti-counterfeiting feature. -Editor
