A machine-readable code is a bar code or a QR code. Spotfire supports several types of codes. You can add a document property to your Spotfire analysis that enables a mobile device to scan a code and filter the results in a data set containing a column of codes.

The example described in this section shows how to configure a Spotfire table visualization with the document property to scan a code, and then add an expression that finds and limits the data to display only the scanned entry. You could use this feature for inventory control, for example.
