Smartphones have revolutionized the way we interact with the world around us. One of the most convenient features of these devices is their ability to scan Quick Response (QR) codes, which are two-dimensional barcodes that can be used to store and transmit information.
QR codes have become increasingly prevalent in recent years, and they are now widely used in advertising, marketing, and a variety of other applications. By scanning a QR code, users can instantly access websites, view videos, download files, and perform a myriad of other actions.

What is a QR code and how does it work?
A QR code is a two-dimensional barcode that can be scanned by a smartphone or tablet to access information or perform an action. QR codes can contain text, URLs, contact information, and more. When you scan a QR code, your device decodes the data and displays it on your screen. You can then interact with the information, such as by visiting a website or adding a contact to your address book.
