Barcode scanners

Today there is no way to do without barcodes. They are just strips with various information on them. Detect such information with special equipment - a scanner. They are in almost all commercial facilities. With the help of barcodes you can find necessary information much faster. When you manually enter the information it takes too long. It is also possible to make mistakes. Working principle First take the required item. After that, scan the position for a couple of seconds. https://i.ibb.co/wwswx2Q/logo.png The system will provide the following indicators: - Product name; - Price; - Possible discount offers.

After that the data processing will be done. The information received will be sent to the cash register terminal. Views of barcode scanners 1. By the method of operation: - Manual - widespread device. Connects via USB. 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 - is a stationary mechanism. In order to interact with it you need to bring it close to the object. This machine has a high productivity. All due to the fact that it works very quickly. It is used in large supermarkets [https://teklynx.com]

- Built-in bar code scanner is used in the cashier's shops. 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 Data is read when it hits the light beam, then sent to the terminal The only negative of this scanner is that the code will not be read if more than 10cm away from the scanner itself. 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; b) long life; 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; b) scans any code format; c) reads data from long distances; d) high speed; e) can work on an inclined plane; f) mounts on stand

Disadvantages of the barcode scanner: 1) Not resistant to shock and vibration; 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 scanning process lasts about a couple of seconds. Supports all existing encodings. Reads data from a distance instead of close range. Can scan codes directly from phone or tablet screen even at an angle. The design is sturdy, shockproof. The only negative factors of this device can be distinguished by its high price. 4. Based on the type of connection - Wireless - connection by cable: standard USB or other types; - Wireless - another name for radio scanner. Connection is via Internet, Wi-Fi, Bluetooth

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.

Selecting a certain barcode scanner depends a lot on the purpose for which it will be used. For example, for trade with excise stamps (alcohol and tobacco products), the model of apparatus with photo system is suitable. Shops with high sales turnover and customers should not save on such equipment. A quality device in the future will facilitate and accelerate the work of staff.
