Barcode scanners

Barcodes have become an integral part of everyday life. They are just strips with various information on them. Such ciphers are read with special scanners. 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. In this case errors cannot be ruled out.
Working principle
First select the desired item. Scanning takes a few seconds.

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

All of the above is processed. Then the information is transmitted to the cash register or terminal.
Views of barcode scanners
1. By the type of service:
- 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. In order to interact with it you need to bring it close to the object. The productivity of this variety is large. All due to the fact that it works very quickly. It is used in large supermarkets https://teklynx.com
- Built-in - is installed in the cash register system. No wires are needed for its operation. This scanner is very convenient, does not take a lot of space and has high productivity.
2. Based on the reading process
- The LED barcode scanner scans the code 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.

The advantages of LED bar scanners:
a) beneficial price;
b) long life;
c) suitable for the smallest barcode sizes.

- Laser - the essence of work is 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) suitable for any format;
c) large distance of use;
d) high speed;
e) does not crash when tilted;
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. Principle of operation is that the program takes a picture and recognizes a barcode. The scanning process lasts about a couple of 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 - through different kinds of cords;
- Wireless or radio bar scanner. Interaction is established through the Internet and other additional programs

5. Based on barcode type
- Linear - has only one beam Linear - has only one beam It is used in small shops
- Two-dimensional - 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. 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. While such equipment greatly speeds up and optimizes the work of the company as a whole.
