When using Layer on a mobile device, the barcode field will have an icon that when tapped will open up your device’s camera to scan a barcode or QR code. The barcode’s value will then be recorded for the field value.
Also available on mobile devices is the ability to search by barcode. The search bar will have a barcode icon that you can tap to open your device’s scanner. The project will search all barcode fields for the corresponding barcode value.
The barcode scanner is currently not available for Android devices.
