OPLIN 4Cast #713: Have QR codes finally found their way out of obscurity?

Posted in 4cast, and QR codes

QR (quick response) codes have certainly had their ups and downs, as far public consciousness goes. I find that, for myself, I only use them regularly when setting up two-factor authentication for online services–often when I use my Yubikey (I keep one in my office and one on my keychain and I love them!). Many services that offer 2FA present a QR code to help set things up, and it’s generally a quick and handy way to go about it. I almost never use QR codes outside of that task…but that may be changing. It appears that, in light of the pandemic, they be having a big moment.
