Various Types of Barcode Scanners.
Another name for a barcode scanner is a barcode reader. It is a gadget that is electronic that reads and output written barcodes to a processor. A barcode is something that can only be read electronically inform of numbers so that it can show the product. A barcode scanner has a lens and a source of light that turns the optical impulses into electric impulses. This device has a decoder circuitry that analyzes the code image provided by the sensor and eventually sends that code’s content to the scanner output port. Most of these gadgets are found in supermarkets and are used in identifying the price of the commodities that a client buys.
There are various types of barcode readers, and hence they can be differentiated through their design. A handheld scanner is a device that has a handle and also consists of a starting button that is started when passing through the barcode.

You hold the pen and go through the system using the same speed. The photo-diode is responsible for creating a wave that examines the length of the bar and the spaces in between the codes.
A laser scanner works as the pen type scanner only that it uses a laser beam as source of light. It also make use of a rotating mirror to read the source of light across the bar-code.
