Generate/Scan QR Code

With the Generate/Scan QR Code plugin I can create a qr easy. But I am having trouble scanning. I see other forums for this but I would like pictures of how to do so.

I haven’t tried the QR plugin. How are you using this plugin to generate QR code? Is the QR code linking to a specific webpage or serial number? I’m curious how to give the QR code the data to feed when scanned by end user. Thanks!
