QR Code (for product testing verification)

A QR code (Quick Response code) is a type of barcode that stores information in a square pattern of black and white squares. For product testing verification, scanning the QR code with a smartphone or scanner retrieves details about the product, such as authenticity, batch number, or test results. It provides a quick, reliable way to confirm that a product has passed quality checks or is genuine, helping consumers and manufacturers ensure safety and compliance.
