QR-Codes in public places are very insecure. And in addition QR-codes
should never be used for financial transactions or other security
sensitive activities.

Not the QR-Codes themself are insecure - its the websites they link to.
Therefore you should always carefully check the URL of the QR-Code
before opening it.

Otherwise you should also say, that links on websites are very insecure
as well and should also not just be opened without checking the URL first.
