What is a Bar Code Reader?

As the title itself suggests, a bar code reader can scan barcodes that have been printed onto an object or are digitally available as an image. Barcode readers tend to be an electronic device that reads and outputs to a computer. In most situations, the online barcode scanner will also include a decoder, which will help scan the encoded data.

What are the Different Types of Barcode Readers Online?

Barcode readers are usually categorized by the type of technology they use. Also, each type of barcode scanner online may be designed to decode certain codes, but not all. Some common types include pen-type scanners, laser scanners, LED or CCD readers, camera-based readers, and omnidirectional online barcode scanners.

Check this short video and find out what information is stored on a BARCODE:

At times, barcode readers are also classified according to the kind of “housing” or functionality they have. These are commonly separated into handheld scanners, wand scanners, stationary scanners, cordless or wireless scanner, and PDA scanner as a few examples. Our barcode online reader can be considered a wireless scanner, along with a camera scanner as well. The method of connection used is wireless, giving you complete freedom from cords and confusing setups.

Why Use ByteScout’s Barcode Scanner Online?

Experience our Online Barcode Reader. It only requires permission to access your webcam or an existing file in order to instantly test and read a variety of barcodes. Our app supports all the popular formats, including the original UPC. It is simple to use, providing users with a friendly interface that allows for quick work to be accomplished. It is an informative and useful tool to have for those emergency situations where you require any type of barcode scanning and testing to be done.

The ByteScout barcode reader is very easy to use. It is one of the online barcode scanners with the help of which users can directly scan from their webcam or a current file present on their computer. There are different barcode types and the following is an explanation of some of the major codes.


How to Read Barcodes from Images


You will need a device that has the capability of scanning the code and a system for the interpretation of the data.

Scanning an item using the store’s barcode scanner will produce product details like the name and the item’s price. The reason is that the app is designed to interpret a specific barcode sample or format( most likely a UPC barcode). It is also linked to the products’ database where a specific barcode represents each product.

Do you know that if you use that store scanner to decode the ISBN barcode of a book, you will encounter an error? Why? The device is not connected to the required database to enable the interpretation of the data scanned. Thus, it is a different digit for a different framework.

One-Dimensional Barcode vs Two-Dimensional Barcodes

Barcodes can be categorized into two:

One Dimensional Barcodes

These are the 1st set of codes that store data by leveraging white and black lines of distinctive thickness and length. Examples are UPC, EAN, ISBN, as well as Code 39.

Two-Dimensional Barcodes

These are also known as 2d code or matrix code. They are the latest generation of barcodes. 2D codes are most times in square shape and have the capacity to store more information compared to one-dimensional codes. Examples are Data Matrix, Aztec code, QR code, and AR Code. You can decode them easily with any barcode scanner online.

How to Read Barcodes using the Bytescout Barcode Online App

You can read 2D barcodes as well as 1D barcodes using ByteScout Barcode App.

  • Open Barcode reader (don’t forget to bookmark it).
  • It will automatically launch your webcam. Once you open the Barcode reader online, your webcam will discover and capture any code in the view.
  • You can allow the app to read an existing file containing a barcode on your PC or device. With the Webcam on, you can hold any item like toothpaste or a magazine that has a barcode. The webcam will show it clearly. As soon as it beeps, it means the barcode has been read.
  • The app also permits you to tweak some settings like which of the codes you want to read-one dimensional or two-dimensional code.

What is a Webcam Barcode Scanner?

It is a scanner that affords you the opportunity of encoding different types of barcodes by leveraging the webcam on your PC.

The laser gun framework set up to identify products in local stores is without a doubt, too expensive to set up. If you want to cut costs, it is advisable to get a free system that has a webcam and use it as a barcode reader. What an exciting way to reduce costs in your new business!

How Does the Barcode Scanner Online Work?

Follow these instructions to use your webcam scanner:

Step one: Configure your webcam

You will need to configure your webcam on your PC or device. Your device or PC must be able to recognize it, and you must have installed the driver on your device.

Step two: Scan Barcode Online

Immediately you launch the Bytescout barcode reader online, bring the barcode you intend to scan closer to the webcam to ensure the image is not blurred. The recommended distance is about two to three inches or 5-8cm.

Some webcam is embedded with a manual focus mode. This enables you to focus on the picture manually or in closer proximity.

Step three: Read Barcodes

The scanner will show the alphanumeric code on your screen.

Click on the ‘scan’ button and eat some popcorn while the Bytescout Online scanner performs its magic.

As soon as it detects any barcode, it will list it on the decoding history screen.

Scanning a QR code

You will need an app or camera to scan QR(Quick Response) codes. If you work with an online barcode scanner using mobile camera and it is malfunctioning, then you will need to use the app.

QR Code

The QR Code is a two-dimensional code. It is also used in 2d barcode scanner online tools. It is recognized from product covering. For the scanner to identify a QR Code, the code must perpetually be square. A sign of extra factors guarantees that the data is held accurately. It is also known as Quick Response (QR) Codes. The following image is displaying the decoding of the QR Code by ByteScout.

Code 128

This type is procured from the ASCII 128 set. It is used largely for packaging purposes. Code 128 highlights a programmed switching context that enables users to configure it for the barcode unit. It treats confirmation via checksum digit and byte equality testing. The ByteScout barcode reader online tool uses Code 128 type effectively. Scan barcode online easily by using our tutorial. The following image is displaying how ByteScout works to decode Code 128.

Code 39

Code 39 is a standard barcode class used for different classifications such as name brands, records, and manufacturing applications. The code set is the combination of numbers 0-9, upper-case letters A-Z, the space character, and various other symbols.

The ByteScout barcode reader online camera can be used to scan Code 39 type when users give the necessary permission to access the camera for scanning the image. As mentioned earlier, it is the combination of alpha-numeric barcodes to apply and is intended for character self-checking, thus excluding the requirement for character counts. The following image is displaying how a free barcode reader online works to decode code 39.

The ByteScout free barcode reader online also scans EAN code efficiently. The EAN, International Article Number (also identified as European Article Number) is a rule representing a barcode symbology and valuation method applied in business to recognize a particular local product sample, in a particular packaging form, from a distinct producer. It is also suitable for the U.S.A. and Canada and JAN of Japan. It is a general code throughout the world. EAN is applied in a POS system that is popular in appliance stores.


ByteScout instantly scans the EAN-8 to decode it swiftly. An EAN-8 is an EAN/UPC symbology barcode and is obtained from the higher Universal Article Number code. It was proposed for application on little packets where an EAN-13 would be too big. The best examples are small packets like smokes, streaks, and chewing gum packages.

EAN-8 is a compressed version of the EAN-extended code. It holds a 3 figure country code, 4 or 5 information digits, and a checksum number. The main objective of the EAN-8 code is to implement a short space. The following image is displaying how barcode number reader online works to decode EAN-8.

Read EAN Codes


The ByteScout barcode number reader online tool can also be used to decode the UPC codes. The UPC code is identified as the Universal Product Code. It is generally accepted in the United States, Canada, UK, Australia, New Zealand, Europe, and other nations for hunting sale products in markets. UPC contains 12 digits that are distinctively allocated to a particular sale product.


UPC-E is another variant of the UPC code. UPC-E barcodes are applied to smaller boxes, where a full 12-digit barcode is too large. It is a ‘zero-suppressed’ variant of UPC  in which the digit, all tracing zeros in the business code, and all foremost zeros in the product code, are subdued.  UPC-E supports the design SDDDDDDE. The method in which a 6-digit UPC-E correlates to a 12-digit UPC-A is defined by the UPC-E digital model and UPC-E equality model. The following image is displaying how the ByteScout online barcode reader decodes the UPC-E.

The Codabar barcode is the traditional code and is applied for transportation/drawing, printing direction, and delivery as well as for managing state equipment. This symbology enables the encoding of series of up to 16 digits, 10 number digits, and 6 special characters like “+” (plus), “-” (minus). There is also 4 starts/stop code options when applying the Codabar. The characters (A, B, C, or D) must be inserted at the start or end of a series. The following image is displaying how the tool scans a barcode online.

Interleaved 2 of 5

Interleaved 2 of 5 (ITF) is a constant two-width barcode encoding symbol. It is applied on 135 films, for ITF-14 barcodes, and on packages of some items, while the items bounded are marked with UPC or EAN. ITF encodes combinations of digits; the leading digit is encoded in the five black lines, while the next digit is encoded in the five white lines interleaved. This is how it works.

Read BarCode Types

Standard 2 of 5

Standard 2 of 5 is a pretty uncomplicated symbology. In this, encoding data is encoded in the breadth of the bars. The extent of the barcode endures only to divide the bars themselves. Also, a bar may be broad or small, a broad bar usually being 3 times as broad as a small bar. The accurate size of the extent is not decisive but it usually has the same breadth as a small bar.

Code 93

The Code 93 barcode is a modernized, more stable, and dense variant of the Code 39 code, which is suitable to understand both letters and numbers. It is applied in the military and automotive domains. It is shorter and more effective than Code 39 and has bigger data repetition, to give greater protection. It also incorporates 5 unique figures that Code 39 does not have. Code 93 cannot be shipped in conventional ASCII characters and each character is denoted by a specific numerical value.

The following image is displaying the decoding of Code 93 by the ByteScout barcode online scanner.
