What is a barcode?
A barcode is a machine-readable visual code used to represent numbers or text. It is common in retail, inventory, shipping, libraries, tickets, and product labeling.

Printing tips
Keep enough white space around the barcode, print with high contrast, and test scanning before using labels in production. Avoid stretching the image because scanners need clean bars.
