What is a QR Code and How Does it Work?

A QR code, or Quick Response code, is a two-dimensional barcode that stores information readable by devices like smartphones. Unlike traditional barcodes, QR codes can hold more data, such as URLs, contact details, or payment information. When scanned, the code directs the user to a specific action, like opening a website or downloading a file.

• Structure: QR codes consist of black and white squares arranged in a grid, encoding data in patterns.
• Functionality: A scanner decodes the pattern, translating it into actionable information.
• Accessibility: Most modern smartphones have built-in QR code readers in their camera apps.

Understanding the basics of QR codes sets the foundation for using them effectively. Next, let’s explore how to scan them across different devices.
