Barcode scanners are devices and systems that record and translate the barcodes from the recognizable images into the alphanumeric digits. The translated information is then sent into a computer via a wired network or through a wireless transmission. The alphanumeric digits are programmed to refer to a specific item and when the numbers are scanned, the information from the database such as prices, the number of items on stock, the items description and even a reference picture are all extracted.
For a long time,1D barcodes have been in use and are still widely used across the world despite the fact that they have a small capacity to hold information. The 2D barcodes on the other hand stores large information due to their intrinsic combination of horizontal and vertical information storage. The 2D barcode, however, needs an Intermax image scanner whereas the 1D barcode scanner can only deal with linear codes. There are various types of scanners depending on what they use to capture the barcode. Some scanners utilize lasers. others use cameras or lights to scan and capture the barcode images before translating them into electronic codes.
Of all the types of scanners from intermax.com.au/resource-centre/barcode-scanner-guide/. The omnidirectional scanner is the most advanced. It is basically a laser scanner but it has additional lenses and mirrors designed to minimize errors. An omnidirectional scanner is capable of reading crumpled or ripped barcodes which would otherwise be damaged faster than the other types of lasers.
Barcode verification involves grading of barcodes based on their quality and according to established standards. Barcode verifiers are precision devices that are used during the grading of barcodes. Barcode verifiers put the 1-D and the 2-D barcodes in different grades based on quality parameters as stipulated by the industry standards. The industry standards are developed by international organizations such as ANSI/ISO and the various industry groups such as the GS1 and the HIBCC. These standards are geared towards enabling interoperability between scanning systems and barcode printing. The barcode verification helps in confirming that a code produced anywhere in the world will be accepted globally. Barcode verification remains the only way to not only assign a specific grade to a given barcode but is also the most reliable way of diagnosing and fixing errors in during barcode marking.
Barcode verification guides producers through the process of barcode marking so as to produce high-quality codes which are easily readable. This is done by the barcode verifiers which does the analysis of the barcode and before assigning quality grades to them which are typically from A to F or a numerical equivalent ranging from 4 to 0.
