Barcode scanners

Barcodes have become an integral part of everyday life. These are special lines that contain certain information. 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. In this case errors cannot be ruled out.

The system will provide the following indicators:

All of the above is processed. The information received will be sent to the cash register terminal.
