By adding a Spotfire Text Area and a details visualization to an analysis with bar code reading enabled, you can provide users with a view to show a scanned code value.

In the dialog, provide a title, such as Scanned Code, and then close the dialog to save the change.
Click the Edit icon to edit the text area, and in the Edit Text Area dialog, insert a property control for the document property AppMachineReadableCode.
