It is a widespread malpractice. Illegal activists use QR codes to lead users to malicious URLs. These URLs look precisely like the original websites.
Due to the small screen size, users can't see the complete URL of the website. If they aren't able to distinguish, they'll end up getting into the trap. Scammers can also access your bank accounts if we're not careful.
Scammers and attackers gather phone numbers from QR codes. And then, they try to sell something as being a genuine person. They can also try to play as bank professionals, and if we provide them with enough information, they can easily make us bankrupt.
