Scan barcodes at your POS register

You can scan barcodes at the register to add items to the cart in a second. Use the camera on your tablet or phone, the iPad or iPhone app, or a barcode scanner. The register matches the code to a product's barcode or SKU, so add those to your products first.

Add barcodes to your products

Open a product in your admin and find the Inventory section. Enter the code printed on the item in Barcode (ISBN, UPC, GTIN, etc.). You can also use SKU (Stock Keeping Unit) for your own codes. The register checks both, and capital letters don't matter.

No barcodes on your items? Print your own. Open Products, then Inventory, and click the print button, Print barcode, next to the product. The label uses the product's barcode, or its SKU if there is no barcode.

How to scan barcodes with a camera

  1. On the register, tap the scan button next to the search box, or the Scan barcode tile.
  2. Point the camera at the barcode. The item goes into the cart.
  3. If the product has variants, pick the variant when asked.
  4. If the camera can't read it, type the code in Scan or type barcode / SKU and tap Look up.

Camera support in browsers

The web register reads EAN-13, EAN-8, UPC-A, UPC-E, Code 128, Code 39 and QR codes. It needs a browser that can read barcodes with the camera. Safari and Firefox can't, so the register tells you and you can type the code instead.

On an iPad or iPhone, the Mawg3 POS app scans with the camera. Use the Scan barcode tile on Home or the scan button in Products.

Use a barcode scanner

Most USB and Bluetooth scanners type the code like a keyboard. Open Scan barcode on the register, then scan. The cursor is already in the code field. Most scanners press Enter after the code, which looks it up straight away. If yours doesn't, tap Look up.

When a barcode doesn't match

If you see No product matches, the code isn't saved on any product. Copy the code from the message, add it to the product's Barcode field and scan again. Also check that the product isn't a draft, because drafts don't show at the register.

Questions people ask

Can I search by barcode without scanning?

Yes. Type the barcode or SKU in the register's search box and the matching product shows up.

Why does scanning work on my laptop but not my iPad's browser?

Safari can't read barcodes with the camera. Use the Mawg3 POS app on the iPad, or a barcode scanner.
