What is a QR Code?

A QR code (Quick Response code) is a two-dimensional barcode that can be scanned using a smartphone camera or a QR code reader. It consists of black squares arranged on a white grid and can store various types of information, such as URLs, text, contact information, and more.

How Does It Work?

When a QR code is scanned, the encoded information is decoded and displayed on the user's device. This allows for quick access to websites, promotions, or other digital content without the need to type in a URL or search for information manually.

Common Uses of QR Codes

• Linking to websites or landing pages
• Storing contact information (vCards)
• Facilitating mobile payments
• Providing access to promotional offers or discounts
• Tracking products in supply chains
