A barcode scanner is a reading device used for reading information written in codes. It is used in retailing like inventory management and sales. It is a small device that can be called the eyes of a point-of-sale system where products are produced for billing.
Types of barcode scanning devices
Technology has made it possible to make a device for every business like a big warehouse and a small retail store. Depending upon your needs and budget, you can buy a laser scanner, image, or CCD laser scanner.
It is a high-tech tool that works with laser technology. Laser light travels through a series of mirrors before reaching the barcode. It is sophisticated technology used for reading 1d barcodes. And it can read the codes even from a distance of 2 feet. But this POS barcode scanner requires much care as it contains multiple fragile plastic parts.
The device comes with a high-end digital camera to capture and scan an image. The captured image is uploaded on the computer the device is attached to and the decoding is done by the computer. It is a useful device as it requires little maintenance. But you will need to take the camera closer to a code you want to scan.
2D Area Imagers
It is an advanced device as it can scan all codes – 1D, 2D, and stacked. Also, it can read the codes from the front, sides, upside, and downside. This way provides much freedom from holding the device before the code as you do with others. While a regular device can read codes only when the codes are placed horizontally, this advanced POS hardware provides the freedom to read the codes swiftly from every direction.
Charged Coupled Devices (CCD) devices come with miniature sensors that generate waveforms corresponding to the codes scanned and decode the information before sending the information to the point-of-sale system. Here the decoding is done inside the scanner instead of the computer.
It is a reading device equipped with a light source and a photodiode. Drag the tip of the device across a code to generate a waveform that correlates to the code scanned. It also decodes the code and sends the information to the computer it is attached to. But you should know more about barcode scanners for sale in India.

It is also a stationary device used for quick reading of barcodes. Since it is embedded on a checkout counter, it is called an in-counter scanner. This POS barcode scanner is useful in grocery stores where customers do self-service. But it isn’t popular in India, where there are little to no self-service grocery stores.
