What is a QR Code?

A QR (Quick Response) code is a type of matrix barcode that encodes information using black squares arranged on a white grid. These codes can store data such as URLs, text, or other information that can be accessed quickly with a scanner. Scanning these codes can save time and simplify access to online or offline resources.
