Buying Guide of Barcode Reader

The use of barcode reader goes into the public theses. No matter to the retailers or big companies, the prominent ability of automatic recognition and convenience operating do great contribution to management. With the help of it, the level of company managing and working efficiency is maintained.

 

However, it is not an easy job to choose a suitable barcode scanner. Now, let’s see several keys you should know before making the deal.

 

To the barcode scanning system, resolution is right decoding minimal bar width. It is a mistake that the higher the resolution, the better the device. A rational customer should choose corresponding resolution decoding device by the condition of real application. In the using progress, if the resolution is very high, the effect of dirty and deinking will be serious.

 

Scanning depth of field is the range of fastest decoding distance and shortest decoding distance, or we can say it is the effective working rage of a barcode scanner. Some scanning device manufactures don’t provide this parameter in the instruction but the scanning distance (the shortest distance).

 

Scan width is the available length of barcode. If you need to scan very long barcode, you need to keep an eye on this parameter. Scan speed is the frequency of lighting on the scanning track.

 

Once passed ratio represent the ratio of reading tag counts and tag sum in the first time. For example, if the times of reading barcode are twice, then the once passed ratio is 50%. In the consideration of application, everyone wants 100%. But it is pity that for the reason of barcode and reader, it is impossible. In fact, only if the tool is made by inferior manufacture, the once passed ratio is high enough for using. This testing target is only applied to the light pen handheld barcode reader.

Code error rate is a very important target of the wrong decoding. It is equal to the ratio of wrong decoding times and sum decoding times. To the scanning system, it is a more important factor than the once passed ratio.

 

After reading so many parameters about the barcode reader, have you learned to know find out the best one? In fact, to provide convenient and reliable products, our Koolerbuy workers have chosen the bests one of them for you. You needn’t to worry about complex parameters. Hope you will find a reliable companion for your work.
