Unlocking the Power of QR Code Technology: A Comprehensive Guide

QR (Quick Response) scanner technology is a type of two-dimensional barcode that contains encoded data. It was introduced by Denso Wave, a subsidiary of Toyota, in 1994.

QR codes can store various types of information, such as text, URLs, contact information, or commands, and can be scanned using a camera-equipped device like a smartphone or a dedicated QR scanner.

The encoded data is deciphered by the scanner, allowing users to access the information contained within the QR code quickly and easily. QR codes have become ubiquitous in various applications, including advertising, marketing, ticketing, and contactless payments, due to their versatility and ease of use.

How Does A QR Code Scanner Work?

Basically, a QR code works in the same way as a barcode at the supermarket.?It is a machine-scannable image that can instantly be read using a Smartphone camera. Every QR code consists of a number of black squares and dots which represent certain pieces of information

?

• QR (Quick Response) scanner technology utilizes a camera-equipped device to scan QR codes.
• When a QR code is scanned, the scanner captures the code's pattern of black squares and interprets it as encoded data.
• The encoded data may contain various types of information, such as text, URLs, contact information, or commands.
• The scanner deciphers the encoded data and performs the corresponding action, such as opening a website, displaying text, or adding contact details.

Example: A user scans a QR code on a restaurant menu with their smartphone. The QR scanner app interprets the code and directs the user to the restaurant's website, where they can view the menu, place orders, or access additional information about the establishment.
