My tech illiterate mother got a bill from a local business and the invoice "helpfully" provided a QR code to the billing page instead of a link (I have verified that she did do business with this company so it shouldn't be a scam). She's on Windows 10 using the Mozilla Thunderbird email client, and does not have a smart phone. I thought this would be an easy problem to solve but I can't find any utilities to do this that don't seem shady from companies I've never heard of.
I've asked her to contact them to send something in a link form that she can just click on but in the meantime I'd really like to find a way to do this so that I didn't just waste an hour trying to research. Can anyone recommend software that can do this? I really don't feel like dealing with malware infestation on top of the issue.
