The difference and advantage of scanning gun two-dimensional bar code and one-dimensional bar code

Release Time:2013-06-06

A two-dimensional barcode that stores information in two-dimensional space in the horizontal and vertical directions is called a two-dimensional barcode.
1. High density coding, large information capacity.
2. Wide range of coding.
3. Strong fault tolerance and error correction function.
4. High decoding reliability.
5. Encryption measures may be introduced.
6. Low cost, easy to make, durable.
 
The one-dimensional bar code only expresses information in one direction (generally the horizontal direction), but does not express any information in the vertical direction, and its certain height is usually to facilitate the alignment of the reader.
The application of one-dimensional bar code can improve the speed of information entry and reduce the error rate, but one-dimensional bar code also has some shortcomings:
Small data capacity: about 30 characters
Can only contain letters and numbers
Barcode size is relatively large (space utilization is low)
The bar code cannot be read after it has been damaged

Scanner one-dimensional bar code and two-dimensional bar code in the role of the difference and advantage
The one-dimensional code can identify the basic information of the product, such as the product name, price, etc., but it does not provide more detailed information about the product. To call more information, the further cooperation of the computer database is required.
The two-dimensional code not only has the function of identification, but also can display more detailed commodity contents. For example, clothes can not only display the name and price of the clothes, but also show what materials are used, the percentage of each material, the size of the clothes, and how many people are suitable for height,
 
As well as some washing precautions, without the cooperation of computer database, simple and convenient.
