ive just heard of an incident where students redirected their books codes to p**n. can i make sure that doesnt happen? also, im using google to generate them, is there a foss alternative as im scared of tracking. lastly, can i make the qr code redirect to a specific page of a pdf as i want people to be able to scan them and immediately land on a specific part
No, its just a coded form of a URL. People just dont know this and use weird online generators / link grabbers. Sometimes these use URL shorteners too, where easy typos can happen
To be more specific, a QR code encodes a string of text. You can put the words “Happy Birthday Nerdlinger” in a QR code if you want.
If the string happens to match the pattern of a URL, then most readers are configured to automatically turn that into a “visit this URL” command for the default web browser.
Yup. Some apps are great for that and also allow stuff like calendar events, contact, mailto, matrix or any other link. I mean you could just write it yourself
