How Barcode Scanners Read Barcodes: An Overview

Discover how barcode scanners work and the methods used to read barcodes effectively.

0 views

The method used to read a bar code is a barcode scanner. There are two main types: 1D barcode scanners and 2D barcode scanners. The scanner emits a beam of light that reflects off the barcode. The scanner measures the reflected light and converts it into electrical signals, which are then decoded into data using specialized software. This data typically includes product information, pricing, or inventory details.
