Barcode and QR scanning

Where to find the scan button

In the POS home, the product search bar has a scan icon on the right (next to the clear button). Tap it — the camera opens full-screen with a corner-bracket viewfinder.

What it does

• Point the camera at a product's barcode or QR
• Unique SKU match — the product is added to cart instantly (same behaviour as tapping its tile, respects the stock cap)
• No match — the raw scanned code drops into the search field so you can see partial matches, or realise the SKU isn't wired to any product yet

Supported formats

• EAN-8 / EAN-13 — European retail barcodes
• UPC-A / UPC-E — US retail barcodes
• Code 128 / Code 39 — inventory labels, shipping codes
• QR codes — for Wemu-generated product QRs or customer loyalty codes

Controls inside the scanner

• Torch — toggle the flash on dark shelves
• Camera flip — switch to front-facing (rarely useful, but some tablets have better front cameras)
• Tap anywhere to dismiss without a scan

Linking a SKU to a product

If the scanner drops the code into the search bar with no match, the SKU isn't linked yet. To fix:

1. Web dashboard → Products → pick the product
2. Set the SKU or Barcode field to the exact code
3. Save — the POS refreshes the catalog within 30 seconds

Generating barcodes in Wemu

Any product without a printed barcode can be assigned one from the web:

1. Product detail → Barcode section → Generate
2. Wemu mints a Code 128 barcode with a unique payload
3. Print it from the same screen onto adhesive labels
