What should go into the QR code?
Choose from lot only, JSON, URL, or free text. If unsure, start with lot only.
Can I add a barcode too?
You can add 1D barcodes like Code128 as an option (e.g., encode the lot number).
How does template saving work?
Save your input as JSON or store it in the browser for quick reuse.
Printed size is off.
Disable fit/scale and print at 100%. Test print one sheet first.
How should the URL look?
Use something like https://.../trace?lot=XXXX and add more params only if needed. Shorter URLs scan better.
