What is a Quiet Zone?
Quiet Zones help maintain the space around a barcode.
Keeping the space around the barcode free of text, symbols, and pictures will help the scanner to see and scan the barcode easier.

A useful device to help maintain the Quiet Zone in some production processes is to include a less than (<) and/or greater than (>) character in the Human Readable Interpretation field, with its apex aligned with the edge of the Quiet Zone.
