What is a bar code reader?

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

What are the different types of barcode readers online?

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

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 online barcode scanner 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.

QR Code

The QR Code is a two-dimensional variant of the barcode. It is also used in online barcode scanner and 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 QR Code by ByteScout 2d barcode scanner online.

Code 128

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

Code 39

Code 39 is a standard barcode class used for different classifications such as name brands, record, 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 barcode 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 free barcode reader online works to decode code 39.

The ByteScout free barcode reader online also decodes EAN barcode 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 the appliance stores.


The ByteScout barcode reader online camera instantly identifies 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 barcode 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.

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, in 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 on 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 barcode supports the design SDDDDDDE. The method in which a 6-digit UPC-E correlates to a 12-digit UPC-A is defined by UPC-E digital model and UPC-E equality model. The following image is displaying how 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 it works.

Interleaved 2 of 5

Interleaved 2 of 5 (ITF) is a constant two-width barcode encoding symbols. 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.

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 extents in the barcode endure 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 extents is not decisive but it usually has the same breadth of a small bar.

Code 93

The Code 93 barcode is a modernized, more stable and dense variant of the Code 39 barcode, 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. The Code 93 cannot be shipped in conventional ASCII characters and each character is denoted by a specific numerical value.
