When a barcode is added to a layer, a visual representation appears, providing an estimate of its size on the target device's screen. It is important to ensure the barcode is large enough for scanning equipment to read it properly.
The data fields that will be encoded into the barcode are displayed on the right side of the interface. For example, if the fields “First Name” - “Last Name” are selected, the barcode will encode data in this format: bill-smith.
