I read a story about Coca-Cola updating some of it’s vending machines across the US, which are touchscreen-based vending machines, and they ran an over-the-air software update to convert them to be touchless by using QR codes. And it’s funny, isn’t it? So many changes have been accelerated by COVID-19 and I didn’t think that necessarily QR codes would be; but perhaps they will.
Because as well as the Coca Cola vending machines, there’s also the UK’s test and trace system. Now, you probably know the story of the app that never was, but instead there’s a web-based system that many places (like pubs) are using where you scan a QR code, which takes you to a website where you check in your details. And it’s kind of training people to use QR codes.
