What is a barcode reader in computer?

A barcode reader (or barcode scanner) is an optical scanner that can read printed barcodes, decode the data contained in the barcode and send the data to a computer. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating for optical impulses into electrical signals.

How a barcode reader reads code into the computer?

The purpose of a barcode scanner is to scan or read a barcode symbol and then provide an electrical output to a computer via a decoder and cable. The decoder recognizes the type of barcode symbology it is seeing, translates the bar and space content and transmits data to a computer in a human readable format.

Is barcode reader an output device?

Like other input devices, a barcode reader is bringing in (inputting) information from the outside world into a computer or other electronic device. If the barcode reader also has a screen that displays (outputs) results or prints results, it would be considered an input/output device.

How does a barcode reader work?

All barcode readers use a light source and sensors to detect and measure the intensity of light reflected back by the white spaces within the unique pattern of parallel bars. The reflected light is detected through a photodiode, producing an electronic signal that corresponds to the barcode pattern.

What is barcode identification system?

Barcode technology is an automatic identification technology generated and developed in computer application and an effective means of data collection designed to achieve the automatic scanning of information. It is widely used in the logistics industry and typically used in the goods sale in supermarkets.

Which software is used in barcode?

What are the advantages and disadvantages of a barcode reader?

6 Advantages and Disadvantages of Barcode Reader | Drawbacks & Benefits of Barcode Reader. 1. Universal . Barcodes are universally accepted technology. They are used behind almost all of the retail items all around the world. Therefore, using 2. Accuracy. Human errors can cause problems in every

How do I use a barcode reader?

Load the program of your choice (database or word processing) where you want to enter the barcode information. Scan your first item with the device–place the red light directly over the middle of the barcode–and wait for the information, including product name, UPC or ISBN number , price, and publisher or manufacturer data, to display.

Why is a barcode reader an input device?

Like all other input devices, a barcode reader is bringing in (inputting) information from the outside world into a computer or other electronic device, which makes it an input device. If the barcode reader also has a screen that displays (outputs) results or prints results, it would be considered an input/output device.

How does barcode reader work?

A barcode reader works by directing a beam of light across the bar code and measuring the amount of light that is reflected back. (The dark bars on a barcode reflect less light than the white spaces between them.) The scanner converts the light energy into electrical energy, which is then converted into data by…
