What are the advantages of bar code technology?

Bar code is by far the most economical and practical automatic identification technology. Bar code technology has the following advantages.

1, input speed: compared with the keyboard input, bar code input speed is 5 times of the keyboard input, and can achieve "real-time data input".

2, high reliability: keyboard input data error rate is one in three hundred, the use of optical character recognition technology error rate is one in ten thousand, and the use of bar code technology error rate is less than one in a million.

3. Large amount of information collection: the traditional one-dimensional barcode can collect dozens of characters of information at a time, and the two-dimensional barcode can carry thousands of characters of information, and has a certain ability of automatic error correction.

4, flexible and practical: barcode identification can be used as a means of identification alone, but also can be composed of a system to achieve automatic identification and identification equipment, can also be connected with other control equipment to achieve automatic management.

In addition, bar code labels are easy to make, there are no special requirements for equipment and materials, identification equipment is easy to operate, no special training is required, and the equipment is relatively cheap.
