How Barcodes Work
Barcodes seem simple, but there's clever engineering behind those lines. Each pattern represents specific numbers or letters that scanners read by measuring the width of bars and spaces. The quiet zones on either end tell the scanner where the code starts and finishes.
What's fascinating is how universal they've become. From checking out groceries to tracking hospital supplies, barcodes handle millions of transactions daily. They're reliable because the system is straightforward - dark lines, light spaces, consistent spacing.
