What Is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode that stores data in a matrix of black and white squares. When scanned with a smartphone or QR code reader, it provides quick access to information such as website links, contact details, or product information. QR codes are widely used in marketing, advertising, and logistics due to their convenience and ease of use.

This can include a website URL, text, or even payment information. QR codes can store a variety of data types, including links, text, or even multimedia content.
