: Redirect QR code Is there a way to "intercept" incoming traffic from a QR code and redirect it to another page of your site? I have a QR code that is printed on physical paper. The scan

@Murray432

You'd have to reprint the code, most QR readers launch the phone's browser so there is nothing for you to detect on the web front end to redirect the incoming link.

Options:-


Reprint the material
Print stickers and literally sticker over the code (pain but we've all had to do it at some point)
Redirect all mobile traffic to /code/ until you can reprint the
material.


Option 3 probably the best one for you right now.

In the future it's best to use url obfuscation for QR codes on printed material, at least this means that you can redirect as needed after the print run.

Probably not. It is likely that the QR code simply encodes the URL. There is not likely to be any further information contained in it that would enable you to detect that the referral came from a QR code, and the User-Agent: string is likely to be that of the web browser that the URL was passed to rather than the QR code scanner program.
