i How to use
- Pick an input method below — USB scanner, manual entry, or phone camera.
- Scan or type the full barcode (20, 24, or 28 digits — partial reads are ignored).
- Read the result. Green = matches all rules and product database. Red = something is wrong; the breakdown shows exactly which segment failed.
- If invalid: reprint the label correcting the segment shown in red. Don't ship the product.
This is the offline desktop file. Database and scanner library are baked into this single HTML — no internet, no server, no extraction needed. Note: camera scanning is disabled under file:// (browser security). Use USB Scanner or Manual entry.
Scanner Input
Tap the box to focus, then scan. KPSCAN auto-validates the moment the full barcode arrives — no need to press Enter (though it works if your scanner sends one).
