Introduction
From the grocery checkout to the Amazon warehouse, barcodes are the invisible language of products. But you don't need a $200 laser gun to read them anymore.
What is a Barcode?
A barcode represents data by varying the widths and spacings of parallel lines (1D barcodes). The most common type is the UPC (Universal Product Code) found on retail packaging.
How Do Scanners Work?
Traditional scanners use red laser lights to detect the contrast between black bars and white spaces. Online Barcode Scanners use image processing to analyze a video feed from your camera, achieving the same result purely via software.
Why Use an Online Scanner?
- Inventory Check: Quickly look up a product you have at home.
- Price Comparison: Scan a code in-store to see if it's cheaper online.
- Dietary Info: Many apps link barcodes to nutritional databases.
