What is a QR code and its history and where I can use it?

We encounter in many of our different daily activities icons bearing symbols. This system has spread due to its fast readability and high storage ratio, as we find it in commercial products, in household appliances and their accessories, in books … almost all things that affect our lives.
At first glance, it appears randomly stacked. It consists of black units arranged in a square shape on a white background. The encoded information can be any type of data (for example: binary numbers, numbers, or kanji symbols).

Qs: What are the symbols, their role, and how they work? .. How to employ this technology and benefit from it… What are the benefits and limits of QR code (quick response code)? and where I can use it?

Quick response code Definition:

The idea of ​​placing a code or code appeared as an important requirement for major stores to perform a simple process by scanning to know the type of commodity and its price. The QR code appeared as a second-generation barcode QR Code is an abbreviation for Response code, which is a two-dimensional code, an image consisting of points or lines numerically arranged in the form of a square

it is used in encrypting personal data and information and its use differs from one person to another and there are those who use it to distinguish their products from other products, and there Who uses it to place links or information to facilitate access it from other users, and it is responsive and is used to save information in a brief form, where a link can be included to any postal address, phone number, or any information entered by the user.

History of the development of the quick response code:


In 1994, Toyota’s “DENSO WAVE” announced the release of the QR Code, which was developed for high-speed reading and tracking of vehicle parts during the manufacturing process.

A QR code has been approved in the automotive industry for use in *Electronic Kanban *. The decision of “DENSO WAVE “contributed to a large extent to the widespread use of codes by making QR codes available to the public so that anyone can use them freely.

In 1997, it was approved as the AIM standard * for use in the automatic identification industry, and the two-dimensional code became standard on EDI as a form of the standard transaction in the Association of Automobile Manufacturers of Japan.

In 2000 it was approved by ISO.
In 2002, the use of the QR code became widespread among the general public in Japan, and that what facilitated this trend was the marketing of mobile phones that contained the feature of reading the QR code.
In 2004, it was small in size so it could be printed in small space and it was approved by JIS standard.

And in 2008, IQR was released with a small footprint.
Icons have also evolved into several classes with high-level design features and enhanced ease of use. One example is that “4qrcode” which applies reading restrictions to meet users’ demands to raise the level of privacy.

Uses of QR code:

It was the beginning of the use of the QR code to track spare parts in the automotive industry, and it became used in many areas, including:

  • In the medical field:
    The Quick Response QR code is used in the medical field with a portable terminal unit to make the test data for medical examinations more accurate, and we can also, through the quick response code, compare the information in the prescription for drug preparation with the basic prescription for the drug to avoid errors when preparing the medicine.
  • In the commercial field:
    The Quick Response QR code is used in the commercial field to help manage the inventory process of warehouse storage with the help of a portable wireless terminal unit so that the inventory can be completed at the maximum speed (real time), and it can also be used as a tool to raise the efficiency of inspection of storage levels.
  • Control the admission of people to special events or seminars (with the help of a mobile QR code) that is
    your entry becomes only for people with a specific quick response (via a mobile card or … etc).
  • In offices:
    The QR code is used in libraries to assist with block checkout and library management.
  • In manufacturing processes:
    The QR code is used in all stages of the production process, from the assembly of raw materials needed to manufacture the product and shipping operations to make them all highly efficient, which also allows tracking of the product.
  • It is used as a business card or as a phone number
    Just slide the camera on it and it calls you directly.
  • It can be used for websites.

How QR code works:

  1. We go to a specialized site to create a quick response code, the best of which is ( QR code generator 4qrcode).
  2. Then after entering, we review the interface of the site.
  3. Then we choose one of the available methods and use it to create our own QR code in the manner of (free text) and write any data we want to put into the QR code that we create, we will notice that the image of the code has changed based on the instructions you entered when Finished.
  4. We save our QR code after clicking on Save.
  5. We write the name that we want to save the symbol in and choose the format that we will use to save our symbol, let it be the PNG format, then we press Save until the code is downloaded directly to our device, and so we have successfully completed the creation of our code.

QR code advantages:

  1. It can be scanned by using a smartphone or any other phone with scanning capability our you can use our QR code scanner.
  2. QR code are versatile, can encode almost all types of data. E.g., numeric, alphabets, special, and binary.
  3. Extremely fast scanning.
  4. Like other 2-D barcodes, the QR code has good fault tolerance. Even if some part of the code is damaged, information constables are decoded from the code.
  5. Store a large amount of information, unlike 1-D barcodes.

QR code limitation:

  1. Smartphones used to scan QR codes are often expensive in comparison with simpler phones.
  2. Relatively new barcode type, people are not much familiar with its use. Requires training in order to fully understand the concept.

Not every aesthetic, contains random patterns of square boxes which might not look pleasing on the product, unlike 1-D barcodes.


The QR code is considered an advanced way to bring innovation in the field of marketing and advertising. On the other hand, there are some restrictions that require a solution. Also, the awareness and appropriate position of the technology will lead to real change in the situation.
