Explain how handheld computers work and what to consider when choosing one

    The main principle of handheld computers is to use the software that comes with the device to identify the characters of the 1D code/2D code, which is a graphic identifier arranged according to certain coding rules to express a set of information. It is mainly used for product tracking, production control and automatic identification. However, choosing the right reader requires understanding your needs and then testing the appropriate reader to know the results. For example, when choosing a handheld computer, consider the following factors:

1. Barcode type and barcode width, such as barcode symbolology, number of digits, density size;

2. The direction and position of the barcode paste, parallel to or perpendicular to the scanning ray?

3. The speed of the assembly line;

4. Scanning distance, distance requirement between barcode and scanner;

5. The vibration of the conveyor belt;

6. The installation of the bracket, whether an adjustable bracket is required;

7. Sensors and alarm devices;

8. What interface is required? Whether it is necessary to form a network to access the same server or PLC;

9. Interface with the background application system;

10. High-speed scanning of barcodes and QR codes in motion, support automatic scanning and command control and other working modes.
