Understanding UPC Barcode Structure and Components
Every product on the shelf carries a silent identifier, a unique string of numbers that governs its movement through the global supply chain. The visual structure includes quiet zones, guard patterns, and data characters, all working together to ensure a scanner can interpret the code accurately, even at high speeds.
These lines vary in width to represent binary data (1s and 0s). To function properly, a UPC code requires specific physical space.
