You want to create something like a database, which will be paid barcode scanner scan method
and to do so, then these bar codes when rescanning on another device were written off in order to avoid repetition scanning of the same code.
The database does not scan, it just keeps.
1C is a function, you can search "program to work with scanners SHK" who know how to store the scanned codes. So they are not duplicated, the base should be one and lie in the network.

The barcode scanner is so pop-eyed thing with a handle, have seen it all in stores. When scanning, it reads data from the image into text and then submitit form. That is your task to obtain these data and to bring the room in DB, checking if it's already there.
