What Are QR Codes and How Do They Work?
QR codes (Quick Response codes) are two-dimensional barcodes that store information in a compact, scannable format. Originally developed for the automotive industry, QR codes have become a popular and powerful tool in marketing, logistics, retail, education, and more.
A QR code can store various types of data, such as:

- Wi-Fi login credentials
- Payment details
- Plain text or messages
