Barcode glitch plunges Covid test centres into crisis

A barcode glitch plunged the UK corona testing system into fresh crisis — with thousands of people turned away from test centres.

Drive-throughs reported problems with their QR codes — scanned to bring up people’s details — up and down the country, with a massive gridlock in South London.

According to The Sun the system had sent out confirmation emails without the QR code, leaving staff turning away valid bookings.
