Dynamic QR codes.

A QR code that holds a short link instead of your address. You can point that short link anywhere, anytime, so a printed code never needs reprinting, and each scan is counted.

A static code stores the link in the pattern itself, so it can never change. A dynamic code can be edited after printing and shows how many people scanned it.

Many sites switch them off when a trial or plan ends. Ours keep sending people to the last link you set, even if you cancel. You just cannot change it until you come back.

Your first one is free. After that, $12 once per code with no subscription, or $8 a month for up to 25 codes.
