The main difference between a QR barcode scanner and a traditional barcode scanner lies in the types of codes they can read:
Barcode Scanner: Typically refers to scanners that can read standard 1D barcodes like UPC codes used on retail products. These scanners use laser or LED technology to scan the parallel lines of varying widths.
QR Barcode Scanner: Specifically designed to read QR (Quick Response) codes, which are 2D barcodes that can store more information than traditional 1D barcodes. QR codes are square-shaped and consist of black modules arranged in a square grid on a white background.
In essence, while both types of scanners scan barcodes, a QR barcode scanner is specialized to handle QR codes, which are commonly used for marketing, product information, URLs, and other applications where more data needs to be stored and retrieved quickly.
