Also, Google Lens.

From wired:

Sometimes the QR code you want to scan is on a website on your phone screen. Google has added Google Lens functionality into the Chrome browser, and you can use it on an Android phone or iPhone with these steps:

Tap and hold on the QR code image.

A menu should pop up. Select Search With Google Lens.

Tap the notification that pops up to open the link. (You will need to be connected to the internet to do this).

This can also be done from Google Photos, and the Google App.
