A barcode reader also called barcode scanner or price scanner is a machine that can read data from a barcode and send it to your computer as an input information. Barcode reader can connect to the computer via wireless or wired medium. It is composed of a scanner and a decoder.
The data which barcode send to the computer can make an information by a software system. Some barcode reader can store data for further use. There are several types of barcode reader. We will discuss main five types of barcode readers in this article.
Types of barcode reader
The most uses five types of barcode reader is given bellow;
- Pen wand barcode reader
- Slot scanner barcode reader
- CCD scanner barcode reader
- Image scanner barcode reader
- Laser scanner barcode reader
Pen wand barcode reader
Pen wand barcode readers are designed for single user to scan package or another item quickly. This is very simple types of barcode reader and not more expensive too.
It consists of a LED light and photodiode. The photodiode can measure the reflection of light reflected from the barcode when a user passes it over a barcode. Thus, a pen wand barcode reader works.
Slot scanner barcode reader
Slot scanner barcode reader is needed to scan a bank card or employee card. We have to pull the card through the scanner’s slot to scan the information.
There are mainly two types of slot barcode reader. One is visible light barcode reader which is more common today. Another is infrared slot barcode reader which is usually being used for security purpose such as verifying ID cards and so on.
CCD scanner barcode reader
CCD stands for Charge Coupled Device. CCD barcode readers also known as LED scanner which has hundreds of tiny LED lights in a row.
CCD scanners are usually used in retail sales which has a better range than pen wand barcode reader. Normally CCDs are very expensive and gives highly accurate information.
Image scanner barcode reader
Image scanner barcode reader also called 2D camera reader because it has a small camera to capture the image of the barcode. They can hold more data than other types of barcode reader.
The camera works with hundreds of tiny lights as a CCD barcode reader. Only difference is that here lights are arranged in different rows. The captured picture is sent to a software and the software then decodes the information of that barcode.
Laser scanner barcode reader
Laser scanner barcode reader is more advanced which can be handheld or stationary. It works with laser beams of light and can scan from more distance like 25 inches to several feet. It gives more speed than any other barcode reader.
