QR codes, or Quick Response codes, are a popular way to encode information in a two-dimensional barcode format. They can store a variety of data, including text, URLs, and contact information. This guide will help you understand how QR codes work and how to use them effectively.

What is a QR Code?

A QR code is a type of matrix barcode that can be read by a camera or a QR code scanner. It consists of black squares arranged in a square grid on a white background. The information encoded in the QR code can be anything from a simple text message to a complex URL.

Key Features of QR Codes

  • Scalability: QR codes can be scaled up or down without losing any data.
  • Versatility: They can store a wide range of data types.
  • Ease of Use: QR codes can be easily created and scanned using various tools and devices.
