What Is a QR Code?

(Tempemailnow.com) – A QR code (Quick Response code) is a two-dimensional (2D) barcode that stores data—such as website URLs, text, contact details, email addresses, phone numbers, or instructions—within a square grid of black and white modules. When scanned using a smartphone camera or QR reader, the encoded information is decoded instantly, allowing quick access to digital content or triggering specific actions.

QR codes bridge the gap between the physical and digital worlds by enabling printed or displayed codes to link directly to online information.

The QR code was developed in 1994 by Denso Wave, a subsidiary of Toyota, originally to track automotive parts during manufacturing. Due to its efficiency, high data capacity, and reliability, the technology has since become a global standard used across many industries. Learn More About QR code.

Key Characteristics of QR Codes

Two-Dimensional Structure

Stores data both horizontally and vertically, unlike traditional one-dimensional barcodes.

High Data Capacity

Can store thousands of numeric or alphanumeric characters—far more than standard barcodes.

Fast Scanning

Designed for rapid detection and decoding by camera-based devices.

Error Correction

Includes built-in redundancy, allowing QR codes to remain readable even if partially damaged or partially obscured.

Common Uses of QR Codes

QR codes are now used globally for a wide range of applications, including:

Web Links – Direct access to websites, product pages, or social media profiles
Payments – Mobile and contactless payment systems
Contact Information – Digital business cards and contact sharing
Wi-Fi Access – Network connection without typing passwords
Ticketing – Event passes, boarding passes, and movie tickets
Menus & Information – Digital restaurant menus, product details, and instructions

How QR Codes Work

Scan – A smartphone camera detects the square finder patterns located in the corners of the code.
Decode – The scanning software interprets the black and white modules as encoded data.
Action – The decoded information triggers an action, such as opening a website, launching an app, or displaying text.
