Japan's NEC Corp. has launched a facial recognition system that identifies people even when they are wearing masks, adapting to a new normal in which face coverings have become a key form of protection against the spread of the coronavirus.

The technology firm had already been working on a system to meet the needs of allergy sufferers who wear masks when the COVID-19 pandemic prompted it to accelerate development.

"Needs grew even more due to the coronavirus situation as the state of emergency (last year) was continuing for a long time, and so we've now introduced this technology to the market," Shinya Takashima, assistant manager of NEC's digital platform division, said.
