What is a QR Code?

A QR code (Quick Response code) is a type of two-dimensional barcode that stores information such as text, URLs, email addresses, phone numbers, and more. It was originally designed for industrial use in the 1990s but has since become widely used across various industries and applications.

QR codes are made up of black squares on a white background, with three types of modules:

• Finder patterns: The square shapes at the top-left, top-right, bottom-left, and bottom-right corners.
• Alignment patterns: The alternating light and dark modules inside the finder patterns.
• Data modules: The actual data stored in the QR code.

Importance and Use Cases

QR codes have become increasingly popular due to their ease of use, versatility, and ability to store large amounts of information. Some common use cases include:

• Marketing and advertising: Businesses can place QR codes on advertisements, flyers, or websites to drive traffic to specific landing pages.
• Product labeling: Companies can attach QR codes to products for easy access to product information, such as ingredients or instructions.
• Event promotion: Organizers can create QR codes for event tickets, schedules, or maps.
• Mobile payments: Users can pay bills or make purchases using their smartphones.
