Today there is no way to do without barcodes. These are special lines that contain certain information. Such ciphers are read with special scanners. There are many retail facilities equipped with them. The equipment facilitates and accelerates viewing of necessary data. If you search the data manually it will take much longer. In this case errors cannot be ruled out. Working principle First take the required item. After that, scan the position for a couple of seconds. (IMG:) You will see on the scanner screen: - Full item name; - Price; - Share.
After that the data processing will be done. Then the information is transmitted to the cash register or terminal. Views of barcode scanners 1. By the method of operation: - Manual - widespread device. A USB cable is required for its operation. The scanner is easy to operate and small enough to be quickly and easily handled. Virtually all handheld bar scanners have an extra stand. Manual scanners are mostly used by small stores and companies dealing with large parcels. Very often the manual scanners are used by logistics companies for scanning parcels and various retail outlets. Stationary scanner is a non-perishable equipment that reads barcodes. In order to interact with it you need to bring it close to the object. This machine has a high productivity. This is due to the high speed of activity. It is used in large supermarkets - Built-in - is installed in the cash register system. Scanning does not require wires. This scanner is very convenient, does not take a lot of space and has high productivity. 2. Based on the scanning method - LED - reads the index by the red beam Information first hits the light, is reflected, then downloaded into the system Main disadvantage is that if you hold a barcode more than 10cm away it will not be scanned. The LED scanner can read only one-dimensional numbers because it was created a long time ago The LED scanner reads only one-dimensional codes, since it was created a long time ago.
Proses of choosing LED varieties: a) beneficial price; (IMG:) durable for a long time; c) good barcode reading ability.
- The principle of laser barcode scanners is exactly the same. The only thing - their light beam is complemented by laser. It's a more sophisticated and innovative device. Benefits: a) accessible even for distorted and small images; (IMG:) suitable for any format; c) large distance of use; d) very fast; e) can work on an inclined plane; f) can be mounted on optional stand
Disadvantages of the barcode scanner: 1) Does not read when the machine is in motion; 2) Doesn't recognize too smooth and shiny surfaces; 3) High cost.
3. Photoscanners barcodes are the latest developments. Principle of operation is that the program takes a picture and recognizes a barcode. The action is very fast for a few seconds. It interacts with all types of data encoding. Reads data from a distance instead of close range. You can also read codes from various gadgets even in a tilted position. It has a robust frame. The only negative factors of this device can be distinguished by its high price. 4. Based on the authorization method - Wireless - connection by cable: standard USB or other types; - Wireless or radio bar scanner. Interaction is established through the Internet and other additional programs
5. Based on barcode type - Linear - single-beam scanner Linear - one-beam scanner It is used in small shops - Two-dimensional - equipped with many infrared beams.
In order to select the right barcode scanner you should know and take into account what it will be used for. If we consider a supermarket that sells cigarettes and alcoholic beverages, in this case it is better to use the photo scanner. Saving money on professional barcode readers for chain supermarkets and big stores is a big mistake. A quality device in the future will facilitate and accelerate the work of staff.
