Nope. Their purpose is to contain an string. The string can be anything,
even an URL. :-)

For instance, I had somewhere a QR code with the identifier and password
of my wifi.

 
   And I use them to login to my bank accounts, governmental websites,
medical/hospital websites, etc., etc.. No URLs involved, because my
browser is already connected to the websites in question.
 
   So QR codes are multi-purpose, *some* are dangerous, but others
*enhance* security/safety/privacy/<whatever>! :-)

 
And AFAIK, the danger is only when opening an URL without pausing.

  Indeed. VanguardLH sort of implied that there are QR scanning apps (or
QR scanning parts of camera, etc. apps), which directly open the URL
without pausing, but didn't give details, so for the moment that's FUD.
