Principle of Operation

QR codes are ubiquitous. Such a code is a unique graphical combination of small squares. Outwardly, it resembles a bar code – a combination of numbers and vertical lines that can be found on any product. The bar code contains information that requires software or a device – a QR code reader to decrypt it.

What does QR stand for?

QR is an acronym and its stands for Quick Response. A QR code can contain any information. Using a physical device or software that is installed on a smartphone, the user can instantly access it. Hence the name Quick Response.

Historical Reference

The QR coding system was born in 1994 in Japan. This coding method was developed by Denso Wave, a subsidiary of Toyota. The first QR codes were used to control produced cars and spare parts.

It was difficult to use traditional barcodes for this since they cannot encode Japanese characters and special characters. Therefore, a type of coding was developed, which later gained popularity in the world.

It took a year to create the first Quarcode. Such a code contained much more information than a traditional barcode, and it took much less time to read.

You can scan a barcode in one direction – strictly from left to right. The main difference between a QR code is that it can be read in two directions: horizontal and vertical. This allows you to store more data. In addition, to scan a QR code, you do not need to hold the device in any particular position. Information is recognized from any angle.

The first scanners in smartphones

Smartphones with a pre-installed QR code reader were first introduced in 2002 in Japan. This has led to an increase in the popularity of QR technology. This method of coding began to be used by many companies from different fields of activity.

Distribution of QR-coding technology

Already in 2004, ordinary users knew how to use a QR code, and why it was needed. Technology continued to improve rapidly. Quar codes gained even more popularity in 2008 with the advent of the first iPhone.

In 2012, QR Code was awarded the Good Design Award for achievements in industrial design. At that time, this coding method was found everywhere: on billboards, in magazines, in leaflets, etc.

And in our time, Denso Wave employees are working fruitfully on the design and functionality of QR codes.

There are many ways in which Quar codes can be used, but there are four main types of coding that are often used.

  • Digital coding. This method is used to record information consisting of decimal digits. One message can contain up to 7089 characters.
  • Alphanumeric method. In this way, numbers from 0 to 9, letters of the Latin alphabet, and space are written. Holds up to 4296 characters.
  • Binary coding. For recording, the ISO-8859-1 encoding is used, intended for Western European languages. One message
    contains up to 2953 characters.
  • Kanji encoding. Used to write Japanese characters. It was this type of encoding that was developed by Denso Wave when creating the first quarter code. Up to 1817 characters can be written in this way.

There are also additional encoding options. For example, structured addition mode allows you to save data in multiple QR codes.

In addition to coding technology, QR codes differ in design. The classic Quar Code, developed in 1994 by Denso Wave, is a black-and-white square with a chaotic pattern. Search symbols are located in the two upper and lower left corners.

The Aztec code is similar to the traditional QR code but has one search pattern in the center. MaxiCode is a type of code used by the United States Postal Service. This code has one search pattern in the center but uses hexagons instead of squares. Semacode is a code similar to a traditional QR but without search patterns.

The rectangular PDF417 code is a cross between a barcode and a quadruple code.

Online QR code decryption

How is the reading done?

The graphic pattern of a QR code is an encoded combination of letters, numbers, and special characters. Each code has search characters that the reader responds to.

With the help of software, each square is assigned a particular value. By the method of algorithmic analysis, information is transformed into a form understandable to the consumer.


The QR code was created as an alternative to the traditional barcode. This marking method has the following advantages:

  • Contains more data.
  • More characters can be used for encoding.
  • The large capacity of the code makes it possible to integrate copy protection into it. This reduces the chance of error.
  • Quarcode is easier to read. Almost any smartphone user knows how to scan a QR code. For reading, you can not use additional equipment. To scan a barcode online, software installation is required.
  • Quarcode can be of any size and can be applied to almost any surface.

The QR code is recognized in two directions, so it is easier for the reader to perceive. There is no need to choose the position of the device, unlike online barcode scanners, which read information only at a certain angle.


Owners of smartphones and other mobile gadgets know how to use a QR code. This explains the popularity of this method of information transfer. The code is used to store:

  • Product information;
  • Direct links to websites and applications;
