What is a QR Code?

A QR code (quick response code) is a type of two-dimensional barcode that can be read using a smartphone camera or dedicated QR code reader. It consists of black squares arranged in a square grid on a white background, which can store information such as URLs, text, contact information, or Wi-Fi network details.

Invented in 1994 by Denso Wave, a Japanese automotive company, QR codes were initially used to track vehicles during manufacturing. Today, they are widely used in various applications, including marketing, payments, ticketing, and information sharing, due to their high storage capacity and fast readability.

Key Features:

  • High Capacity: Can store significantly more data than traditional one-dimensional barcodes.
  • Omni-directional Readability: Can be read from any direction (360°), making them quick and easy to scan.
  • Error Correction: Built-in error correction allows QR codes to be scanned even if they are partially dirty, damaged, or obscured.
  • Versatility: Can encode various types of data, including alphanumeric characters, Kanji/Kana, binary, and more.

Common Use Cases:

  • Marketing: Linking to websites, product pages, or promotional videos.
  • Contact Information: Storing vCard data for easy addition to address books.
  • Wi-Fi Access: Allowing users to connect to a Wi-Fi network by simply scanning a code.
  • Payments: Facilitating mobile payments in stores or online.
  • Event Ticketing: Used for entry and validation at events.
