What is a QR Code?

A Quick Response (QR) code is a type of two-dimensional barcode that stores information in the form of pixels. It’s called “quick” because it can be scanned quickly by a smartphone or other mobile device, using a camera and specialized software. The QR code consists of black squares on a white background, arranged in a specific pattern to hold data.

Defining the Concept

A QR code is essentially a machine-readable code that can store various types of information, such as:

• Text: URLs, phone numbers, email addresses, and short text messages.
• Images: Photos or graphics, which can be used to display additional content or provide visual context.
• Contact Information: Business cards, social media profiles, or other contact details.

Importance and Use Cases

QR codes have become increasingly popular in recent years due to their convenience and versatility. Some key use cases include:

• Marketing and Advertising: QR codes can be used to promote products or services, provide discounts, or offer exclusive content.
• Event Management: Scanning a QR code can check-in attendees, provide event information, or display schedules.
• Retail and E-commerce: QR codes can be used for inventory management, product information, or checkout processes.
