Several important parameters of barcode scanner

1. Resolution of the barcode scanner
The resolution of the barcode scanner is an important parameter to measure the width of the narrowest bar that is read incorrectly. The full English name is: MINIMAL BAR WIDTH, abbreviated as MBW;
When choosing a scanning gun, it is not that the higher the splitting rate of the device, the better, but the scanning gun with the corresponding resolution should be selected according to the barcode density used in the specific application, because the barcode scanning gun with high resolution will not scan the barcode. The quality also has higher requirements, such as when the barcode quality is not high, it may not have a good effect.
2. the scanning width of the barcode scannerThe scan width indicator refers to the value of the physical length of barcode information that can be read by the scanning beam at a given scan distance.
3. Scanning speed of barcode scanner
The scanning speed refers to the scanning frequency of the scanning beam on the scanning track per unit time.
4. One-time recognition rate of barcode scanner
The one-time recognition rate represents the ratio of the number of tags read in the first scan to the total number of scanned tags. For example, if the information on each barcode label needs to be scanned twice, the recognition rate will be 50%. From the perspective of practical application, of course, it is hoped that every scan can pass, but unfortunately, due to the influence of many factors, it is impossible to require a recognition rate of 100%.
Note: The test index of one-time recognition rate is only applicable to the hand-held light pen scanning recognition method. If the laser scanning method is used, the scanning frequency of the beam on the barcode label is as high as hundreds of times per second, and the signal obtained by scanning is repeated.
5. The bit error rate of the barcode scanner
The bit error rate is an extremely important test indicator that reflects the misidentification of the barcode scanner identifiable label system. The bit error rate is equal to the ratio of the number of false identifications to the total number of identifications. For a bar code system, the bit error rate is a more serious problem than the low one-time recognition rate.
