Then Apple included QR code recognition into their iPhone camera app.
And then the COVID pandemic caused QR codes to pop up in restaurants with links to "touch free" menus.
QR codes can contain a variety of information. You can create your own here.
But for URLs, it's even easier than that.
Google has included a QR code generator in the latest versions of Chrome. I just noticed the new icon in Chrome's address bar.
Point your smartphone camera at that and see what happens.
