It wont work, except to get you charged with vandalism, or worse because 'muh holoocough!'
"The error correction capability enables the restoration of the data even after there is distortion, dirt, or damage. Hence, a QR Code keeps functioning even when a part of it is removed, damaged, or even obscured with a finger."

You could do it if you understood the underlying theory well enough, but honestly, it would be easier to just replace their qr codes with your own.
Heck if you wanna get really ambitious, you could set up phony "check-in" locations with your own qr codes pointing to redpilling documents.
Just throw the papers away.
