Who Invented QR Code? The Fascinating History Behind This Technology.

Table of Contents

Did you know that QR codes can store up to 7,089 characters, making them far superior to traditional barcodes? Not only are they great for marketing, but they can also be used for authentication, ticketing, and even payments. While QR codes are widely used in some countries like Japan and China, they have been slower to catch on in the United States and Europe. And if you think QR codes are just black and white, think again – they can be customized with different colors and designs. Plus, they have a built-in error correction feature, ensuring they can still be scanned and read even if damaged. QR codes have certainly come a long way since 1994 when they were first created for tracking vehicles and parts in the manufacturing industry. It’s clear that they are a versatile tool that deserves more attention globally.

The Origin and Inventors of QR Code

Quick Response or QR codes are two-dimensional barcodes that can be decoded with a smartphone or a QR code scanner. These codes were invented in 1994 by Masahiro Hara, a Japanese engineer from the company Denso Wave Corporation. The main purpose of QR codes was to increase the efficiency of the manufacturing process by tracking the automobile parts on the assembly line. They were originally used in Japan, but have now become popular worldwide.

Development of Scanning Technology

The development of scanning technology and mobile devices have been critical in the evolution of QR codes. Traditional barcodes used for inventory management issues were limited by the printing quality, and they were only readable in one direction. QR codes, on the other hand, could store more information and could be read from any direction.

The Need for Quick Response Codes

As businesses sought to streamline processes and reduce friction, they turned to QR codes. QR codes could store up to 7089 digits or 4296 characters, allowing for a larger capacity for data storage for advertising and marketing purposes. The flexibility and utility of QR codes make them appealing for businesses as they could be used for coupons, product information, or URLs.

Innovation of the QR Code

QR codes were designed to be decoded quickly and accurately, allowing for easier tracking and access to information. The introduction of QR codes marked a significant improvement to the world of barcodes as they eliminated the issue of poor print quality and allowed for more information to be stored.

The Original QR Code Concept

The concept of QR codes was initially developed to track vehicles and their parts in the factory. The technology evolved from a one-dimensional barcode to a two-dimensional barcode that could store more data. The QR code can now be used for various purposes, such as tracking inventory, product identification, and engaging communication to customers.

The Involvement of Denso Wave Corporation

Denso Wave Corporation is the primary company behind the invention and popularization of QR codes. The company saw the need for quicker and more efficient manufacturing processes and was inspired to develop a technology to increase the efficiency of the assembly line. The QR code was initially developed for this purpose, but it has now become a valuable tool for businesses worldwide.

The Popularization of QR Codes

The rise of mobile devices played a significant role in the popularization of QR codes. When smartphones were introduced, the ability to scan QR codes became possible, and businesses took notice. QR codes are now used in various applications, from mobile payments to advertisements, e-commerce websites, and product packaging.

The Applications of QR Codes Today

Despite being around for over 25 years, QR codes have continued to evolve beyond their original use for inventory management. They have become a valuable tool for businesses, especially those in the retail and hospitality industries. Here are some applications of QR codes today:

  • Product packaging: QR codes can take customers to a website that displays more product information, including the ingredients and allergens of a product.
  • In-store promotions: Customers can scan a QR code to receive discounts or special offers in-store.
  • Mobile payments: QR codes can be used to make mobile payments, eliminating the need to carry cash or credit cards.
  • Marketing: QR codes can be used to link customers to a landing page with more information about a product or service.

Overall, QR codes are incredibly versatile and have become more popular in recent years. With the rise of contactless payments and increased mobile device usage, QR codes are becoming an increasingly useful tool for both businesses and consumers.
