Barcode Technology - QR Code Barcode               Hide the description

QR code is a specific matrix barcode (or two-dimensional code), readable by dedicated QR barcode readers and

camera phones. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be text, URL or other data..

Valid characters: ASCII 1-255

Which of the numerous types should I use to create a QR Code?

If you have no special wishes, simply choose QR Code. It creates a the smallest QR Code that is possible.

The QR code system was invented in 1994 by Masahiro Hara from the Japanese company Denso Wave. The initial

design was influenced by the black and white pieces on a Go board. Its purpose was to track vehicles during manufacturing; it was designed to allow high-speed component scanning. QR codes are now used in a much broader context, including both commercial tracking applications and convenience-oriented applications aimed at mobile-phone users (termed mobile tagging). QR codes may be used to display text to the user, to open a webpage on the user's device, to add a vCard contact to the user's device, to open a Uniform Resource Identifier (URI), to connect to a wireless network, or to compose an email or text message. There are a great many QR code generators available as software or as online tools that are either free, or require a paid subscription. The QR code has become one of the most-used types of two-dimensional code..

QR codes are used in some augmented reality systems to determine the positions of objects in 3-dimensional

space. QR Codes are also being used to deliver Augmented Reality experiences.

Multimedia QR Codes are also used to direct users to specific multimedia contents (such as video, audio, images,

documents, etc.).

This barcode types has no human readable text based on the specification. The ShowText property has no effect,

when using one of this codes.

Who Uses QR Codes?

Today QR Codes have many uses, including transport ticketing, commercial tracking, entertainment, product labeling, and marketing. In short, you can use a QR code in virtually any situation where you want to send people to a specific website. It is now becoming more common for people to use QR Codes when looking at a product in-store. They often go in-store to look at the physical product and then use their smartphones to compare prices. Depending on how technological the retailer is, they can scan QR codes to find additional information about the products that interest them..

QR Code is one of the many barcode formats currently in use.

A Barcode is a method of representing data in a visual, machine-readable form.

The barcode formats has two categories:

One-dimensional (1D) --- Barcodes represented data by varying the widths and spacings of parallel lines.

Two-dimensional (2D) --- Using rectangles, dots, hexagons and other geometric patterns to represented data.

Check digit:

Calculated according to Reed-Solomon-Error correction, this barocde generate program calculates the check digit automatically.

Alternatively, you can specify the symbol size. Select one of the types with fixed-size for this purpose, e.g. QR Code 45x45. The error correction is selected automatically depending on the amount of data as good as possible.

Comparison of Data Matrix and QR Code

Both Data Matrix and QR Code are two-dimensional barcode, which are able to contain a considerably great volume of information with a small area. However, there are many differences between Data Matrix and QR Code.

Human Readable:

Most barcodes display their corresponding values below them, which makes it possible to human read and manually  enter the barcode values into the equivalent system when the barcode label is worn out and cannot be read by the barcode scanner.

The Advantages of using barcodes:

If you want to reduce costs and save time, using barcodes is a good choice. Whether you are a company or a non-commercial organization, to improve efficiency and reduce overhead, barcodes are a valuable and viable option, which is economical and reliable.

Using Barcode system eliminates the possibility of human error. The error rate of manually entering data is
significantly higher than that of scan barcodes. Barcode scanning is fast and reliable, and it takes much less time than manual data entry. Especially when using a QR code, hundreds of characters can be read and entered into your system instantly.

Using a barcode system can make the working process simple and easy, so it can reduces the employee training time. It only takes a few minutes to master the barcode scanner to collecting data, employees no need to familiar with the entire inventory or pricing process. This also reduces the cost of employee training.

The bar code design and printing cost are low. Generally speaking, no matter how they are used or where they are posted, the cost is not high. They can be customized economically, in a variety of finishes and materials.

The barcode system is very versatile, it can be used for any necessary data collection. This may include pricing or inventory information or management information service system. In addition, because barcodes can be affixed to almost any surface, they can be used not only to track the product itself, but also to track the production process, shipments and equipments.

Using barcode system will improve the inventory control is improved, it can track inventory accurately, inventory levels can be reduced it will lower the rate of eavesdropping. The location of the inventory and device can also be tracked, thereby reducing the time it takes to find the inventory and device.

The barcode system provide better data. Because a barcode can store various information such as inventory and pricing, especially when using QR Code, it can store thousands of characters, so the data stored in the barcode can be quickly obtained by the barcode reader, this fast turnaround ensures that time is not wasted on data entry or retrieval. In addition, the barcode can be customized to include other relevant information as needed. They provide fast and reliable data for various applications.

When barcodes are used in management information systems, they can promote better decision-making. Because data is obtained quickly and accurately, you can quickly obtain a full range of information for the entire company or organization, so it is possible to make more informed decisions. Better decisions can ultimately save time and money.

Barcodes are cheap and user-friendly, providing an indispensable tool for tracking data from pricing to inventory. The end result of a comprehensive bar code system is reduced overhead.

Frequently Asked Questions About QR Code Barcode

What is the origin and development process of QR Code?

QR Code was invented in 1994 by a team led by Masahiro Harada of the Japanese company Denso Wave, based on its original use for marking car parts. It is a two-dimensional matrix barcode that can be used for a variety of purposes.

Later, the encoding and decoding rules of QR Code were formulated into multiple international standards, such as AIM International, JIS X 0510 and ISO/IEC 18004:2015.

The reason why QR Code has to develop multiple standards is to adapt to different application scenarios and needs, such as data encoding method, symbol format, error correction rules, decoding algorithm, etc. Different standards may have different advantages and limitations, such as scanning speed, capacity, compatibility, etc. The development of multiple standards will also help the internationalization and popularization of QR Code, allowing more people to use it.

What is the difference between QR code and 1D barcode?

The difference mainly lies in the encoding method and information capacity.

QR codes use a two-dimensional square matrix, which can store more information and represent more data types.

One-dimensional barcodes use one-dimensional lines, can only store a small amount of information, and can only represent numbers or letters.

There are other differences between QR codes and one-dimensional barcodes, such as scanning speed, error correction capabilities, compatibility, etc.

In some situations, why should QR Code be used instead of one-dimensional barcode?

It is because QR Code has the following advantages:

QR Code can store more information because it uses a two-dimensional square matrix instead of one-dimensional lines. One-dimensional barcodes usually only store a few dozen characters, while QR Codes can store thousands of characters.

QR Code can represent more data types, such as numbers, letters, binary, Chinese characters, etc. One-dimensional barcodes usually can only represent numbers or letters.

QR Code can be scanned and recognized faster because it has four positioning marks and can be scanned from any angle. One-dimensional barcodes usually need to be scanned from a specific direction.

QR Code is more resistant to damage and interference because it has error correction capabilities that can recover partially lost or obscured data. One-dimensional barcodes generally do not have such functionality.

Why are QR codes faster to scan?

The reason why QR codes scan faster is that they can express information in both the horizontal and vertical directions, while one-dimensional codes can only express information in the horizontal direction.

QR codes also have some special geometric patterns, such as positioning patterns, alignment patterns and correction patterns, which can help the scanner quickly identify the position and direction of the QR code.

QR codes also have certain error correction capabilities. Even if part of the QR code is blocked or damaged, the data can still be recovered.

Will QR codes replace one-dimensional barcodes?

Won't.

QR codes and one-dimensional barcodes are two different encoding methods, each with its own advantages and disadvantages.

One-dimensional barcodes can only express information in the horizontal direction, while 2D codes can express information in both horizontal and vertical directions.

One-dimensional codes can only hold 30 characters, while two-dimensional codes have a large information capacity, with a maximum data capacity of 1850 characters.

QR codes can directly store product information without connecting to another database.

The large size of one-dimensional code and low space utilization determines the low information capacity, while the two-dimensional code is relatively small in size (high space utilization) and has the ability to resist damage.

The error correction rates of QR codes are divided into four levels: L, M, Q, and H from low to high. The maximum error correction rates of each level are 7%, 15%, 25%, and 30% respectively, while the one-dimensional codes There is no strong error correction function.

What are the advantages and disadvantages of QR Code?

Advantages:

More data can be stored, including text, addresses, phone numbers, website addresses, videos, maps, etc.

Disadvantages:

Specific scanning software or applications are required, unlike 1D barcodes which can be read with any scanner.

High print quality and clarity are required, otherwise they may not be recognized.

There may be a security risk because users cannot directly see the scanned content or the destination URL.

Is QR Code the only two-dimensional barcode?

No. QR Code is not the only two-dimensional barcode.

According to principles, two-dimensional barcodes can be divided into two categories: matrix type and stacked type.

Common types of 2D barcodes include:

What are the future development prospects of QR Code?

QR Code, like Data Matrix and other QR codes, has broad application prospects.

Two-dimensional barcodes have many advantages that one-dimensional barcodes cannot compare with. Although it is still in its infancy, driven by the constantly improving market economy and rapidly developing information technology, coupled with its unique characteristics, two-dimensional barcodes , countries' demand for the new technology of two-dimensional barcodes is increasing day by day.

Especially in the past two years, two-dimensional barcodes have begun to be applied in many industries, and many far-sighted manufacturers have also begun to get involved in the field of two-dimensional barcodes.

Compared with other automatic identification technologies, 2D barcodes have unique advantages
With the development of science and information technology, automatic identification technology is becoming more and more popular. The key points of automatic identification technology are mainly in improving data quality and input speed and eliminating human interference. Among them, automatic identification technologies that perform well include barcodes, magnetic cards, IC cards and radio frequency identification. However, two-dimensional barcodes have obvious advantages in terms of information carrier cost, information volume, confidentiality, anti-pollution and anti-interference, and standardization, and have good prospects for promotion and application.

First of all, in the application field of automatic identification technology, two-dimensional barcodes have many advantages:

1) The production cost of forms and documents using two-dimensional barcodes is low.

Two-dimensional barcodes can be printed using common inkjet printers, laser printers, and thermal transfer printers, and can be printed on paper, cards, or PVC cards. Therefore, compared with other automatic identification technologies, it is low in cost and has good practical value.

2) Forms and documents using two-dimensional barcodes have good fault tolerance and long service life.

Various forms and documents may be damaged and contaminated to varying degrees during use. Therefore, higher requirements are placed on their service life and machine reading capabilities. The 2D barcode uses an error correction algorithm and has strong error correction capabilities. Even after part of it is damaged, it can still be read by a machine through error correction.

3) Reduced dependence on the main system and network, thereby reducing costs and improving reliability.

The two-dimensional barcode is a portable data file that can carry a large amount of information itself and does not need to be connected to an external database. Therefore, when calculator and database support are not available, the two-dimensional barcode can also be read through a portable data terminal. information in the barcode, thereby reducing dependence on the main system and network, reducing usage costs and improving reliability.

4) The machine-readable function of documents is realized.

The machine-readability and anti-counterfeiting capabilities of documents are the hallmarks of the new generation of documents. Two-dimensional barcodes can encode important information such as the holder's name, certificate number, blood type, gender, etc., and can be automatically read by machines, solving the problem of automatic entry of document data information.

5) Improved the anti-counterfeiting capabilities of documents.

Two-dimensional barcodes have good anti-counterfeiting capabilities. Using two-dimensional barcodes on documents can improve the anti-counterfeiting capabilities of documents by mathematically encrypting the data information represented by the two-dimensional barcodes. Currently, mathematical encryption technology is already a very advanced and mature technology in the world. Therefore, the anti-counterfeiting ability of the document can be greatly increased.

Therefore, the high technology of two-dimensional barcode has great promotion and application value.

Secondly, 2D barcodes have market space.

As a new barcode technology, 2D barcode has been widely used in fields such as national defense, medical care, commerce, finance, and logistics management. Because two-dimensional barcodes have large information capacity, good confidentiality and anti-counterfeiting properties, and low cost, they have very broad application prospects. It is foreseeable that two-dimensional barcode technology will bring considerable social and economic benefits to the development of the information industry and modern economic construction.

Especially products in the pharmaceutical and electronic fields. Medical and electronic products are small and do not have enough space to accommodate traditional barcodes. The high density of 2D barcodes allows automatic identification of these products. For example, some electronic chips are expensive and must be tracked. In addition, the use of two-dimensional barcodes for mandatory controlled drugs in Western countries is also imperative in other countries, so the above technology will become increasingly important.

Two-dimensional barcodes have now entered the stage of systematic application in Western developed countries. Their application fields and usage methods have largely guided the development direction of the world's two-dimensional barcodes. Manufacturers and dealers of 2D barcode related equipment want to enter a wide range of fields, involving a wide range of areas and closely related to people's daily work and life, such as railway transportation, ID cards, household appliances and public utilities. This is almost Involving every family and every person, this indicates that 2D barcodes will enter our lives and penetrate into our lives.

In recent years, information technology and automated management have developed rapidly. Driven by the information industry and commercial automated management, two-dimensional barcode technology, one of the important means of automatic collection of information data, has been rapidly promoted and applied. Since 1998, sales of two-dimensional barcode reading equipment have grown exponentially, and the development momentum is satisfactory. There is no doubt that information technology and modern management are global development trends. As an important part of information technology, two-dimensional barcodes have broad room for development with the development of information technology and modern management, the improvement of people's awareness and deepening of understanding, and the increase in people's anti-counterfeiting requirements for products and various documents.
