Barcode Scanners

Barcode Scanners at Work in a Retail System

If you delve a little deeper into the countless beeps that exist at a busy point of sale you may be left wondering what exactly is behind each beep to achieve the desired result in a pre-defined way.


To use a barcode or to take advantage of the fact that the barcode is present in the product, the first requirement is a barcode scanner.


What is a barcode scanner?

A barcode scanner also known as a barcode reader is an input device used to capture and retrieve information about the scanner product. 


This helps in the automation of the process and thus increases the accuracy of the speed and efficiency of the business process.


Barcode scanners may be a fixed standard without hands or portable data terminals. Another way of classification can be within image scanners and laser scanners. 


But they use a connection with a computer through a serial port, a keyboard port and a wedge which is an infrared device. Some major brands in the field of POS automation are Nexa Epson Zebra etc.


How It Works?

A barcode scanner uses a light beam that falls on the barcode printed on the product. When this light beam is distracted from the product it is measured based on the fact that the dark stripes on the barcode reflect less light compared to the light spaces between the dark stripes.


 The scanner then converts the light energy into electrical energy. It is further converted by the decoder in the form of data as output. This final output is then displayed on the computer screen.


This barcode scan involves scanning a particular barcode and then searching the database of hundreds and thousands of products to match it to the exact one and display relevant details of that product.


Precautions in choosing a code scanner

Every business has its unique requirements and hence the features and functionality when choosing automation tools make the difference in the way they change the environment. 


When choosing a scanner it is very important to understand your type of use if it requires an internal scan at a particular point or requires an external product scan or both ways. 


Moreover, there are different types of barcode symbols. Between the standard 1D and 2D icons used in barcode, different scanners have different decoding capabilities. The right one depends on the requirements of your business.


If the environment is exposed to chemical debris or extreme heat dust, it is important to choose a particularly durable and rugged scanner. 


In case mobility is one important feature then a wireless scanner is the best choice with which the team can navigate all over the place towards achieving the goal of a barcode scanner.


By choosing the right barcode scanner for your business

The whole purpose of using barcodes and assimilating standardization of the business process comes at work. When barcode scanners beep at your point of sale you can be relaxed while handling larger quantities.
