When you are operating a barcode scanner, usually the four cases in above photo happen mostly.
Dia. 1 : The distance between barcode scanner and targeted barcode is proper.
Dia. 2 : The distance is same as Dia. 1, but the barcode size is larger, so the scan width of scanner does not cover all the barcode. This is just like a people standing very close to an elephant, he can see clearly the elephant’s skin, but he can not see the full view of elephant.
Dia. 3 : Same barcode size as dia. 2 with longer scanning distance. In this case, your scanner may not still decode the barcode. It’s like a people stands farther from an elephant for seeing the full view, but the distance is too far to see the detail of its’ skin. In this case what you need is a long-range scanner.
Dia. 4 : The barcode size is too small with large data, so the barcode resolution is high. In this case, your scanner may not read this kind of barcode. We can imagine that when we read a letter, and the words are written too small. The closer our eyes approach the words, the fuzzier words we see. In addition, the small-sized barcode might be printed by a commercial ink-jet printer, not industrial. So the black dots might be feathering, which may cause a reading error. ( For 1D barcode, you can see some black bars spreading out and covering white bars’ area. )
CANMAX now has various solution for above mentioned situations. This year, we will be promoting more new 2D models which carry Honeywell’s powerful 2D engine – N6703. With our own developed firmware, our 2D solutions can meet most of your requests. Today, we already have passport / barcode reader, CM-2D700 ( which we call it “Swan”. ) By the end of 2019, we will have wireless and handheld solutions with powerful long-range engine. This new generation also performs impressively.
To give our users a better experience, CANMAX will keep our technology at the top of barcode industry.
