Analysis and Design of the Code Quick Response (QR) Code Matrix Code

Introduction

In recent years, the QR Code has emerged as the most popular two-dimensional code, surpassing other codes such as PDF147, Datamatrix, and Maxicode. The QR Code is a two-dimensional matrix code consisting of a collection of black and white modules arranged in a square form. The advantages of QR Code are located in its large data capacity, high reading speed, and small printing areas. This article aims to provide a comprehensive analysis and design of the QR Code matrix code, including its working mechanism, error correction mechanism, capacity and size, and benefits for readers.

Understanding QR Code

The QR Code is a two-dimensional matrix code that consists of a collection of black and white modules arranged in a square form. The QR Code reading process begins with determining the type of data contained in it, which is shown through the indicator mode. Next, the QR Code version is determined, which shows the size and capacity of data storage. The essence of the decoding process is to change the data to 8-bit binary code or word code.

How does QR Code work?

The QR Code reading process involves several steps:

  1. Determine the type of data: The QR Code contains information about the type of data it stores, which is shown through the indicator mode.
  2. Determine the QR Code version: The QR Code version shows the size and capacity of data storage.
  3. Decode the data: The decoding process involves changing the data to 8-bit binary code or word code.

Error Correction Mechanism

To overcome distortion that may occur due to damage or dirt, QR Code uses the Reed-Solomone error correction code. This code is able to improve up to 30% distortion in the code. The allocation of beets data is set by bit 1 representing the black module and bit 0 representing the white module.

Error Correction Mechanism: Reed-Solomone Code

The Reed-Solomone error correction code is a powerful tool that helps to correct errors in the QR Code. This code is able to improve up to 30% distortion in the code, making it a reliable choice for storing data.

Capacity and Size

QR Code can store up to 7089 numerical characters or 4296 Alfanumeric characters. The more data saved, the greater the QR code version needed. This has an impact on the size and area printing area.

Capacity and Size: Factors Affecting QR Code

The capacity and size of the QR Code are affected by several factors, including:

  1. Data storage: The more data stored, the greater the QR code version needed.
  2. Printing area: The size of the printing area affects the size of the QR Code.
  3. Error correction: The error correction mechanism affects the size of the QR Code.

Conclusion

The main advantage of QR Code lies in its ability to store more data than other codes with smaller printing areas. With a large storage capacity, QR Code is the right choice for various applications, ranging from storing contact information to accessing digital content.
