A: Hi. It depends on the type of QR code you're using:

Default Dynamic QR codes — yes, you can delete these. Once deleted, the code will no longer be active and anyone scanning it will land on a 404 page.

Static/Pasive QR codes — these cannot be deactivated, as they have the destination URL permanently encoded in them. They will always point to the original target regardless of any changes on our end.

Let us know if you have any other questions!
