When to change the link after printing
The sticker is already on the wall. The offer, menu, or form behind it changed. You still need that print to work.
When a fixed code is enough
If the destination never changes — a permanent website or a one-off event that is over — a normal downloadable code is fine.
When you need to edit later
Menus, seasonal pages, booking links, and campaigns often move. Create the code with Generate on this site so you get a stats page and can keep using the same printed code while the target updates through your flow on QRcode Global when you need a full cabinet.
Save the stats link
After you generate, bookmark the statistics page. That is how you find the code again later.
