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
A QR code just links to a URL. If you link to a URL that you own or control, it’ll be fine. The problem comes when people use a link shortener that allows the destination to be changed later, or if they lose control of the domain or its backend.
To make this a bit more precise, a QR code is a link. It’s just a different encoding of text, in a format that’s easy to read using cameras.
