Suddenly, everybody seems to be scanning QR codes - pointing their smart phone at the menu, ordering, and paying for it; no waiting to catch an eye; no physical contact. QR codes have been around since the nineteen-nineties, but suddenly, with Covid, their time seems to have come. So why did it take so long for them to catch on? Peter White finds out more. First broadcast on You & Yours, 5 February 2021.
