Understanding QR Codes

What is a QR code?

At its core, a QR code (short for Quick Response code) is a two-dimensional barcode that consists of a grid of black squares on a white background. These codes can store a significant amount of information, including URLs, text, contact details, or even multimedia content. QR codes act as gateways, allowing users to access digital content by simply scanning them with their smartphones.

How do QR codes work?

When you scan a QR code with your phone’s camera, a QR code reader app decodes the information embedded within the code. This information is then processed, allowing your device to perform specific actions or display relevant content. It’s like a digital bridge, connecting the physical world with the digital realm seamlessly.

Types of QR codes

QR codes can be broadly classified into two types: static QR codes and dynamic QR codes.

  1. Static QR codes: These QR codes contain fixed information that cannot be changed once created. They are suitable for situations where the encoded data remains constant, such as displaying a website URL or contact information.

  2. Dynamic QR codes: Unlike static QR codes, dynamic QR codes can be edited and updated even after creation. This flexibility makes them ideal for scenarios where the linked content needs to be modified regularly, such as updating a promotional offer or redirecting to different web pages.
