What is a QR Code?

A Quick Response (QR) code is a type of two-dimensional barcode that stores information such as text, URLs, phone numbers, emails, and even vCards. The term “Quick Response” was coined by the inventor of the QR code, Masahiro Hara, in 1994.

Definition

• A QR code consists of a square or rectangle with black modules arranged on a white background.
• Each module represents one bit of information (0 or 1).
• The corners of the QR code contain a unique finder pattern to help the scanner identify the code.
• The middle section contains the data being stored.

Importance and Use Cases

QR codes have become increasingly popular due to their versatility and ease of use. Some common use cases include:

Use Cases

• Marketing: Place QR codes on business cards, flyers, or billboards to direct customers to a website or landing page.
• E-commerce: Add QR codes to product packaging or advertisements to link to the product’s web page or allow for easy checkout.
• Events: Use QR codes as tickets, programs, or even interactive exhibits.
• Education: Create interactive lessons by placing QR codes on textbooks, whiteboards, or educational materials.
