QR code - is it temporary or permanent?

Marketers are concerned about the expiration date of the QR code because sometimes links lead to incorrect pages.
Why does this happen?
Firstly, a QR code is a stable and permanent tool for attracting people to an online page.
Secondly, if programmers/managers do not change or delete the page that the QR code links to, it will work forever.
Thirdly, the content of the page can be changed, but the web address cannot be altered!
Engage and inform customers through QR codes; it is convenient and effective.
