QR Code (Quick Response Code)

What is the Full Form of QR Code?

The full form of QR Code is Quick Response Code. This two-dimensional barcode has revolutionized the way we access information and interact with products and services in our daily lives.

What is Quick Response Code?

A Quick Response Code, commonly known as a QR code, is a type of matrix barcode that contains information in both vertical and horizontal directions. It consists of black squares arranged on a white background, forming a unique pattern that can be quickly read by digital devices such as smartphones and dedicated QR code scanners.

Origin and Development of Quick Response Code

The Quick Response Code was invented in 1994 by Denso Wave, a Japanese automotive company subsidiary. Initially developed to track vehicles during the manufacturing process, QR codes quickly gained popularity due to their ability to store more information than traditional barcodes and their ease of scanning.

How does Quick Response Code work?

QR codes function by encoding data into a two-dimensional grid of black and white squares. When scanned by a compatible device:

  1. The device's camera captures the QR code image
  2. The QR code reader software analyzes the pattern
  3. The software decodes the information stored in the code
  4. The device then performs the intended action, such as opening a website or displaying text

Types of Quick Response Code

There are several types of QR codes, including:

  • Static QR codes: Contain fixed information that cannot be changed after creation
  • Dynamic QR codes: Allow for updating the linked content without changing the code itself
  • Micro QR codes: Smaller versions for limited space applications
  • iQR codes: Rectangular QR codes that can be customized in shape and size

Functions of Quick Response Code

QR codes serve various functions, such as:

  • Linking to websites or social media profiles
