QR codes are two-dimensional barcodes that store information in a digital format. They consist of black squares on a white background, arranged in a specific pattern that can be read by smartphones or other devices equipped with a camera. Scanning a QR code from a photo allows users to access the hidden information stored within it.

What is QR Code Scanning?
