What is a QR Code?

QR codes, or Quick Response codes, are two-dimensional barcodes that contain information such as text, URLs, phone numbers, and more. They were first developed in 1994 by Masahiro Hara of Denso Wave to track parts during manufacturing.

A QR code consists of several key elements:

• Finder Patterns: These are the square dots on each corner of the QR code that help the scanner locate it.
• Alignment Patterns: These are the lines inside the finder patterns that indicate how the QR code should be rotated and aligned for scanning.
• Timing Patterns: These are the alternating black and white modules (squares) that make up the majority of the QR code.

Importance and Use Cases

QR codes have numerous applications, including:

• Marketing: Businesses use QR codes to promote products or services by linking to websites, landing pages, or special offers.
• Event Tickets: Event organizers can use QR codes for ticketing, providing attendees with easy access to event information and tickets.
• Product Tracking: Manufacturers can use QR codes to track inventory, monitor shipments, and improve supply chain management.

Navigate to the chat window where you want to share or scan the QR code. This can be a group chat or an individual conversation.

Wait a few seconds for WhatsApp to process the QR code. You should see a loading animation, followed by the content of the QR code being displayed on your screen.

Practical Uses

QR codes have many practical uses in everyday life:

• Restaurant Menus: Restaurants can use QR codes to provide customers with digital menus, eliminating the need for paper menus.
