You're able to perform barcode scanning on the Register, if you've purchased and paired/connected an existing scanner.
On the StoreHub app, tap on Search Products (the magnifying glass icon) on the top right of the Register screen.
Scan your barcodes. When you scan an existing barcode (a barcode which you have entered for the product in the BackOffice), it will automatically add the item to the cart.
Scanning a non-existing barcode will prompt you to add that item's barcode as a new item.
If you decide to add a new item by scanning a non-existing barcode, you can enter the new item's details on the spot. When you select a Quantity for the new item, it will make the product have a 'Simple Inventory' type (for tracking your stock movement).
