The use of these devices has become very popular and almost no retail outlet can do without them. Barcode scanners have become main tools labor of modern sellers. The speed of performance of their duties, and hence the income of the outlet, directly depends on the competent selection of the device.
The use of these devices significantly increases the speed of data processing, maximally excludes the possibility of errors when entering them.
What you need to know when choosing a device?
Before purchasing devices, it is required to determine what barcode scanners being purchased should be able to do, because they vary considerably in their capabilities. First, you need to know what codes the device should recognize. If you need barcode scanners to automate a retail outlet, it is more profitable to purchase one-dimensional. But already for the receipt /checkout of goods, you will need a two-dimensional one (besides, they can read 1D codes).
Barcode Scanner Resolution
Inexpensive modifications of devices are not able to recognize codes in case of poor print quality. And also they often do not read small and even slightly damaged codes. Thus, we can conclude that there is a direct dependence of the cost of the device on the subsequent speed of the trading zone, and hence the profit from it.
Barcode Scanner Types
Several of the following types of devices are presented:
- multi-surface reader;
- "Light pen" for recognition from flat surfaces;
- multifunctional devices with built-in memory and processor;
- slot-type devices.
A distinction is made between handheld and desktop scanners, as well as in a combined version. Stationary multi-plane vertical and horizontal models are widespread, they are equipped with outlets with a small number of customers.
Distance required to recognize codes
Most cheap devices have a major drawback that makes them less attractive, despite the price. This often applies to contact scanners. More expensive models allow scanning from an interval of up to 76.2 cm. Special devices have been developed that have the ability to recognize codes from 2-3 m.
Additional features
Some devices, in addition to the basic functions, are equipped with IR sensors that can automatically read codes. There are devices with light and sound alarms that confirm the correctness of recognition.
The "scan button" function is very convenient for identifying product information that has
