BBC: How Covid turbocharged the QR revolution
QR codes (quick response codes), a technology from the 1990s, which is proving to be very useful in the Covid era.
Several start-ups are using the QR code for retail storefronts. Stockholm-based Ombori invented its Grid technology, which allows retailers to have a digital screen displaying QR codes, and offers passers-by the opportunity to purchase items right from the street after viewing photos and videos of them.
The system is used by firms in more than 24 countries, including clothes store H&M, Danish furniture chain BoConcept and hotel group Radisson Blu.
