To use the camera on your mobile device
Enable the SCAN setting for the desired column from the column list in the Data >> Columns tab of the app editor:

Within the app, the column will include an icon to indicate its input may be scanned:
When the icon is tapped, the device's camera will be activated to read the barcode or QR code. The scanned data will be entered as the column value.
If any column that is scannable is also searchable, the app's built-in search box at he top of the app screen will also allow scanned input, as indicated by the scan icon:
