Barcode field can drastically simplify your work with the Libraries, especially when working with a large number of products.
To add this type of field while creating or editing a Library, click on Add field, and choose Barcode option. Set the name for this field, a hint, adjust Display options, Advanced parameters (Type — Barcode, QR Code or NFC, Barcode format, Dependencies), and set Validation options.
Once you have added this field, you can add the entries using the barcodes, or search for existing entries in the Library by scanning a barcode. While you’re browsing the Library, you will see the icon in the lower part of your screen: tap it to Search for a barcode in the Library, or Add a new entry.
