How Does a Barcode Scanner Work?

A typical barcode scanner consists of three main components: A light source A sensor A decoder The scanner emits light onto the barcode, which reflects back into the sensor. The sensor captures this reflected light and converts it into electrical signals. Then, the decoder processes these signals and translates them into readable data such as product IDs or serial numbers. This data is then sent to a system via USB, Bluetooth, or other connection types.
