# Annotations

The Annotations section of the Be.Smart T4I contains tools allowing for quick modifications of the dimension text by adding predefined symbols and values before or after the dimension text. It also contains tools to transform important data, e.g. iProperties, into a machine-readable form (QR code or Data Matrix).
