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. There are many retail facilities equipped with them. The equipment facilitates and accelerates viewing of necessary data. When you manually enter the information it takes too long. 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;
- Share.

All of the above is processed. The information received will be sent to the cash register terminal.
Views of barcode scanners
1. By the type of service:
- The manual barcode scanner is the most popular device of all other types. 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.

2. Based on the reading process
- 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:

- The principle of laser barcode scanners is exactly the same. But the beam is illuminated by laser. The model is more modern, so it's improved.
Benefits:
