How to test

1. Open this page on a laptop or second screen.
2. On the iPhone (Safari, HTTPS), open /index.php, sign in (auto-bypassed in demo), and pick a From location.
3. To scan an SKU: tap 📷 next to the search box, point at one of the SKU barcodes below.
4. For lot-tracked items, the lot section opens automatically — tap 📷 in a lot row and scan one of the lot barcodes for that item.
5. Match the location: the SKU must be present at the From location you picked, and the lot must exist at that location too.

Use the format toggle below to render all barcodes as Code 128 (1D), QR Code (2D), or Data Matrix (2D). The decoded value is the same in every format — only the visual encoding changes. You can also print this page for offline testing.
