What are the characteristics of barcode technology?

The characteristics of barcode technology are: \x0d\( 1) simple. Bar code symbols are easy to make and scanning operation is simple. \x0d\(2) The speed of information collection is fast. The keyboard input speed of an ordinary computer is 200 characters per minute, while the information input speed of bar code scanning is 20 times that of keyboard input. \x0d\(3) The amount of information collected is large. With barcode scanning, information of dozens of characters can be collected in turn. Choosing barcodes with different codes can increase the character density and double the information collected. \x0d\(4) Strong reliability. The error rate of keyboard input data is 1: 300, and the error rate of optical character recognition technology is about 1: 10000. However, through bar code scanning, the error rate is only one in a million, and the first reading rate can reach over 98%. \x0d\(5) Flexible and easy to use. As a means of identification, bar code symbols can be used alone, or can be combined with related equipment to form an identification system to realize automatic identification, and can also be linked with other control equipment to realize automatic management of the whole system. At the same time, when there is no automatic identification device, manual keyboard input can be realized. \x0d\(6) Large degree of freedom. The degree of freedom of the relative position between the recognition device and the barcode label is much greater than that of optical character recognition (OCR). \x0d\(7) The equipment has simple structure and low cost. Bar code symbol recognition equipment is simple in structure, easy to operate and does not need special training. Compared with other automation technologies, the cost of popularizing bar code technology is lower.
