Barcode Scanning

The Scan page uses your device camera to read barcodes from filament packaging. It’s the fastest way to add new spools or look up product details.

Opening the scanner

Tap Scan in the bottom nav (mobile) or sidebar (desktop). Grant camera permission when prompted.

Scanning a spool

1. Point your camera at the barcode on the spool or box
2. Hold steady — the scanner detects it automatically (no button press needed)
3. If the barcode matches a known product, its details appear instantly
4. Tap Add to inventory to create a spool from that product

Tip

Barcodes on the side of the spool usually scan better in low light than the small codes on cardboard boxes.

When the barcode isn’t recognised

If the barcode doesn’t match anything in the catalog:

• Create a product — tap Add new product and fill in the details
• The barcode is automatically linked to the new product/variant so future scans work immediately

Searching by barcode manually

Can’t scan? In the Products search bar, paste the barcode number directly. The catalog searches barcode fields too.

Adding barcodes to existing products

1. Open a product → select the variant
2. Click Add barcode
3. Type or scan the code

Now any scan of that barcode resolves to this variant automatically.

• EAN-13, EAN-8, UPC-A, UPC-E
