Database with barcode scanning capability?

Question

Barcodes

It is required to create something like a database into which barcodes will be entered using the scanning method
, and it is necessary to make sure that these barcodes are then written off when they are rescanned on another device in order to avoid rescanning the same code.

Answer 1

A barcode scanner is such a pop-eyed thing with a pen, everyone has seen it in stores. When scanning, it reads the data from the image as text and immediately submits the form. That is, your task is to get this data and enter the number into the database, checking if it is already there.
