Today there is no way to do without barcodes. They are just strips with various information on them. Such ciphers are read with special scanners. They are in almost all commercial facilities. The equipment facilitates and accelerates viewing of necessary data. If you search the data manually it will take much longer. It is also possible to make mistakes.
Process of reading data
First take the required item. Scanning takes a few seconds.

The system will provide the following indicators:
- Full item name;
- Price;
- Possible discount offers.

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 - is a stationary mechanism. You need to hold it against the goods in order to operate it. This machine has a high productivity. This is due to the high speed of activity. It is used in large supermarkets https://teklynx.com
- 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 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) low cost;
b) long life;
c) good barcode reading ability.

- The principle of laser barcode scanners is exactly the same. But the beam is illuminated by laser. It's a more sophisticated and innovative device.
Benefits:
a) can read even damaged small barcodes;
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 scan shimmering objects with glitter;
3) Prices high.

3. Photoscanners barcodes are the latest developments. The device works by reading the data from the picture. The scanning process lasts about a couple of seconds. Supports all existing encodings. 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. There are no disadvantages, only a high price in the market.
4. Based on the type of connection
- Wireless - connection by cable: standard USB or other types;
- Wireless - another name for radio scanner. Interaction is established through the Internet and other additional programs

5. Based on barcode type
- Linear - single-beam scanner Linear - has only one beam It is used in small shops
- Two-dimensional - with many infrared beams.

Selecting a certain barcode scanner depends a lot on the purpose for which it will be used. If we consider a supermarket that sells cigarettes and alcoholic beverages, in this case it is better to use the photo scanner. Shops with high sales turnover and customers should not save on such equipment. While such equipment greatly speeds up and optimizes the work of the company as a whole.
