Types of Barcode Scanner

Consumers utilise barcodes and scanners when shopping, renting cars, attending large events, flying, and even going to the doctor. They’re on storefronts and social media. Barcodes are more than product lines and spaces: Barcode scanning systems track massive data, improving productivity and efficiency. Understanding barcodes and how to use them with a good barcode scanner will help your business.

The Barcode

Barcodes are widely utilised for encoding data in a visual pattern that barcode scanner machines can decipher. Barcodes have a wide range of applications, one of which is the centralised recording of product information in a computer software system. The Wrigley Company’s packet of chewing gum had the first barcode in June of that year. These days, you can scan a barcode and instantly know the price and availability of any product in a store or warehouse, even though the largest retailers in the world, small and home-based enterprises who ship products online rely on barcodes and scanners to maintain track of their deliveries. Both linear and two-dimensional barcodes exist.

The Universal Product Code (UPC) is the most widely recognised, a linear barcode consisting of two parts: the barcode itself and a 12-digit UPC number. The barcode’s first six digits are the manufacturer’s unique serial number. The item’s number is the following five numbers. The final digit is a check digit, and the scanner uses it to determine whether or not a valid barcode was scanned. A linear barcode often holds text information. A 2D barcode, on the other hand, is more involved and may store more data, such as a price, quantity, URL, or even an image. Information contained in a 2D barcode must be read using an image scanner rather than a linear barcode scanner. The ubiquitous QR codes are unique 2D barcodes that can hold more data than their 1D counterparts.

The Barcode Scanner

In most cases, a barcode scanner will have three main components: the light source, the sensor, and the decoder. A barcode scanner “reads” a barcode by shining a red light, converting the code’s black and white components into matching text. A barcode scanner’s light sensor picks up the red light reflected from the barcode and converts it into an analogue signal for transmission to the decoder. The check digit is used to verify the barcode, and the decoder translates the signal into text. The computer software system that keeps track of every product’s maker, price, and amount in circulation receive the transformed text from the scanner. Due to differences in reading distance and work volume capacity, some Barcode Scanners for Sale are better suited for different industries. A handful of the barcode scanners that may be found on the market today are described below, along with some background information on how they function.

  • Pen-type Reader: The end of the pen has a light source and a photodiode.
  • Laser Scanner: Similar to a Pen-type Reader, but uses a laser beam.
  • Camera-based Reader: A barcode reader with a camera and image processing to read barcodes.
  • CCD Reader: has several light sensors to read barcodes.
  • Omni-Directional Barcode Scanner: incredibly advanced and effective at decoding poorly printed, creased, and even ripped barcodes on merchandise.


Barcodes are an efficient and straightforward method of information storage. Numerous ways exist for transforming, storing, and monitoring this information to enable eCommerce businesses to function smoothly and effectively.
