Extended information:

Bar code technology has the following advantages:

1. Fast input speed

Compared with keyboard input, bar code input speed is five times that of keyboard input, and "instant data input" can be realized.

2. High reliability

The error rate of keyboard input data is 3%, that of optical character recognition technology is 1/1, and that of bar code technology is less than 1/1.

3. A large amount of information is collected

The traditional one-dimensional bar code can collect dozens of characters at a time, and the two-dimensional bar code can carry thousands of characters, and it has certain automatic error correction ability.

4. Flexible and practical

Bar code identification can be used as an identification method alone, or it can be combined with relevant identification equipment to realize automatic identification, and it can also be connected with other control equipment to realize automatic management.

In addition, bar code labels are easy to make, and there are no special requirements for equipment and materials. The identification equipment is easy to operate, and it does not need special training, and the equipment is relatively cheap.
