Have You Ever Wondered How Barcode Scanners Work? You Can Now Look at This Short Guide

Nowadays, it is hard to find an industry that doesn’t use barcodes, and therefore barcode scanners. So surely you’ve used one, hunted down barcode scanners for sale, and maybe even needed barcode scanner repairs, however, have you ever stopped to wonder how a barcode scanner works? 

1) The head of the barcode scanner shines a light – either LED or laser – onto the barcode. This light scans one part of the barcode at a time. 

2) This light then reflects back to the scanner and is detected by a light sensor known as a “photoelectric cell”.  Photoelectric cells, or “photocells”, are the part of the device that is designed to read reflected light. The white parts of the barcode reflect light back while the black part reflects almost no light, creating a distinct message. 

3) This sequence of black and white (reflected and non-reflected light) is converted into a series of 0s and 1s by the machine – white stripes becoming 0s and black stripes 1s. 

4) This number series is now sent as data to a computer, where the code is analyzed by a software program and converted into relevant information, such as an item’s price.
