What are the characteristics of 2D barcodes compared to 1D barcodes?

Summary. <>

Hello dear, glad your question What are the characteristics of one-dimensional code and ***?

Features of 1D barcodes:

1) One-dimensional barcode technology is relatively mature;

2) The information capacity is relatively small;

3) 1D barcodes cannot represent Chinese characters or image information.

2D barcodes can capture information in both horizontal and vertical directions.

2D barcodes have the following characteristics:

1) Large storage capacity.

2) Strong damage resistance.

3) High security.

4) Fax and photocopying are possible.

5) Printing diversity.

6) Strong anti-interference ability.

7) The symbology is more abundant.

Hello dear, glad your question What are the characteristics of one-dimensional code and ***? Characteristics of one-dimensional barcode: (1) one-dimensional barcode technology is relatively mature; 2) The information capacity is relatively small; (3) The one-dimensional barcode cannot represent the large-cavity search of Chinese characters or the rolling history of images.

The two-dimensional barcode can obtain information from both horizontal and vertical directions. Two-dimensional barcodes have the following characteristics: (1) Large storage capacity.

2) Strong damage resistance. 3) High security. 4) Fax and photocopying are possible.

5) Printing diversity. 6) Strong anti-interference ability. 7) The symbology is more abundant.

Hello, dear, thank you for your patience, the answer has been found for you, you check it out, ·· Thank you! <>

1.Appearance: 1D code: 1D code is composed of vertical black bars and white bars, black and white, and the thickness of the stripes is also different, usually there will be English letters or Arabic numerals under the stripes.

:*** is usually a square structure, not only composed of horizontal and vertical barcodes, but also polygonal patterns in the code area, the same texture is also black and white, different thicknesses, *** is a dot matrix form.

2.Function: One-dimensional code: can identify the basic information of the commodity, such as the name of the commodity, **, etc., but can not provide more detailed information of the commodity, to call more information, the need for further cooperation of the computer database.

: It not only has a unique identification function, but also can display more detailed product content. For example, clothes, not only can show the name of the clothes and **, but also can show what material is used, the percentage of each material, the size of the clothes, how tall people are suitable to wear, and some washing precautions, etc., without the cooperation of computer databases, simple and convenient.

3.Pros & Cons:

One-dimensional code: mature technology, widely used and less information, only support beam file English or digital, low equipment cost, need to be combined with computer database.

: dot matrix graphics, high information density, large amount of data, error correction ability, coding patent rights, need to pay fees, *** cannot be changed after generation, high security, band mask supports a variety of languages, including English, Chinese, numbers, etc.

The decoding reliability is much higher: it is much lower than the average barcode decoding error rate of 2/10 of a million airfriends, and the bit error rate is not more than 1 in 10 million.

High-density encoding: large information capacity: can accommodate up to 1850 uppercase letters or 2710 numbers or 1108 bytes, etc.

The storage capacity of barcodes is relatively large.

Among the common ***, black and white *** is the more common.

The information flow is large, the coding range is strong, the fault-tolerant energy family has a strong source sail force, the error correction function, the decoding reliability is high, the encryption measures can be introduced, the cost is low, the production is easy to crack, and the durability is durable.

Dear, hello, I am happy to answer your questions about the composition and characteristics of one-dimensional barcodes and two-dimensional barcodes Appearance: One-dimensional code: One-dimensional code is composed of longitudinal black bars and white bars, black and white, and the thickness of the stripes is also different, usually there will be English letters or Arabic numerals under the stripes.

:*** is usually a square structure, not only composed of horizontal and vertical barcodes, but also polygonal patterns in the code area, the same texture is also black and white, different thicknesses, *** is a dot matrix form. One-dimensional code *** function:

One-dimensional code: can identify the basic information of the commodity, such as the name of the commodity, **, etc., but can not provide more detailed information of the commodity, to call more information, the need for the computer database to further close the grip with. ***：

: It not only has a unique identification function, but also can display more detailed product content. For example, clothes can not only display the name of the clothes and the price of the hidden grid, but also show what material is used, the percentage of each material, the size of the clothes, the height of the person who is suitable for wearing, and some washing precautions, etc., without the cooperation of the computer database, simple and convenient. Advantages and disadvantages of one-dimensional code:

Mature technology, widely used Less information, only support English or numbers, low equipment cost, need to be combined with computer database ***: dot matrix graphics, high information density, large amount of data, error correction ability, coding patent rights, need to pay fees, *** cannot be changed after generation, high security, support a variety of languages, including English, Chinese, numbers, etc.
