TOPIC: Barcode scanners

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. 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.

You will see on the scanner screen:
- Full item name;
- Price;
- Share.

After that the data processing will be done. The information received will be sent to the cash register terminal.
