Bar Scanner guide
The whole loop, step by step — from how you lay the bars out to the sheet landing in a chat.
- Make sure every bar number is sharp and fully visible — avoid glare, blur, and shadows.
- Lay the bars out neatly, 5 per row, in reading order (left → right, top → bottom).
- Keep rows even. An uneven row (e.g. 5, 5, 6, 5) can be misread — a 6-bar row may be detected as 5 and miss a number.
- One photo can hold many bars; add multiple photos for large batches, and crop to the bar-number area if the photo is busy.
- 1Lay the bars out
Five per row, in reading order, and every row the same length. The odd bar out is the classic miss: a long row gets read at the length of its neighbours and one number vanishes silently.
- 2Add the photos
Phone camera or file upload, several photos per batch. Each lands as a numbered thumbnail that keeps its own count.
- 3Crop to the numbers
Double-click a thumbnail and frame the band where the serials are stamped. A bar cut off at the edge has to be reshot, not re-cropped.
- 4Scan
One tap reads the batch photo by photo. Stop it part-way, or rescan a single photo without touching the rest.
- 5Verify
Detected numbers line up next to the photo they came from. Fix anything in place; nothing exports until you say so.
- 6Read the dots
Amber means check this bar: an unreadable character, a duplicate, or a format unlike the rest of its group. It is a prompt, not a verdict.
- 7Export and send
A clean .xlsx in the standard bar-list layout. On a phone, share it straight to WhatsApp from the browser — no PC in the loop.
Diagrams of the real workflow, drawn in the tool's own layout. The bar numbers shown are invented, and reading this guide uses none of your scan quota.
