Barcode scanner – how does it work?

A barcode scanner emits a beam of light that falls onto the barcode, where the light is reflected by the spaces between the black bars. The reflected light returns to the scanner and hits a mirror, which directs the beam onto a photodetector located on the circuit board. Such a code can contain a string of characters that, when correctly matched in a database, can provide information about the product’s name, type, and price, or convey data about a specific person to whom the code is assigned. In our store, you will find both wired and wireless scanners.

Barcode and 2D Code Readers and Scanners

Barcode and QR code readers and scanners are easy-to-use devices used to automate the process of identifying people and objects using a barcode or multidimensional code (QR, AZTEC, Datamatrix) that is read by a scanner. Such a code can contain a string of characters that, when appropriately assigned in a database, can inform about the name, type and price of a product or convey a message about a specific person who has their code assigned.
