How Do Barcodes Work

What is Barcode?

A barcode or Universal Product Code can be a way of representing data during a visual, machine-readable form. Initially, barcodes represented the data by varying the width and spacing of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), are often scanned by specialized optical scanners, called code readers. Later, two-dimensional (2D) variants were developed, using rectangles, dots, hexagons, and other geometric patterns, called matrix codes or 2D barcodes, although they are not intrinsically using bars. Huh. 2D barcodes are often read or deconstructed using application software on mobile devices with inbuilt cameras, like smartphones.

History of Barcode

In 1948, Bernard Silver, a graduate student at the Drexel Institute of Technology in Philadelphia, Pennsylvania, president of a local organic event, listening to the Food Fair, had one of the deans to automatically read product information for checkout. Asked to research the system. His friend Norman Joseph Woodland spoke of the request, and said that he started demonstrating on the spread of the system. Ultraviolet ink was used in his first work system, but the ink faded very easily and was expensive.

Noting that the system was practical with further development, Woodland left Drexel, moved to his father’s apartment in Florida, and continued to perform on the system. His next inspiration came from Morse, and he created his first barcode from the sand on the beach. “I just extended the dots and dashes downwards and made narrow lines and wide lines of them.” To read them, he adapted the technology from optical soundtracks into films, employing a 500-watt incandescent light bulb through paper on an RCA 935 photomultiplier tube (from a film projector). He later decided that if it was printed as a circle instead of a line, the system would work better, allowing it to be scanned in any direction.

How Does Barcode Reader Work?

In short, a barcode can happen thanks to encoding information in a visible pattern (those black lines and white spaces) that a machine (barcode scanner) can read.

The combination of black and white bars (also mentioned as elements) represents different text characters that follow a pre-established algorithm for that barcode (more on the type of barcode later). A barcode scanner will read this pattern of black and white stripes and translate them into a line of tests that your retailing system can understand.

Types of barcodes

1. Dimensional (1D) barcode

The 1D barcode is a series of black and white bars that will store information about the type, size, and color of a product. You will find 1D barcodes on the highest universal product codes (UPCs) of a product’s packaging. It helps track packages through UPS and package delivery service providers such as FedEx, US Mail and Canada Post.

2. Dimensional (2D) barcode

2D barcodes are more complex than 1D barcodes. They will include more information than just text, such as price, inventory level, and even product image. There are many barcode scanners that support 2D barcodes. While not all barcode scanners can read 2D barcodes, Light speed Retail POS is compatible with many wireless barcode scanners that support 2D barcodes

Barcode Generator

Our barcode generator can be a simple tool that you will use to create QR, UPC-A, EAN-8, EAN-13, code39, code128 and ITF barcodes. These symbiology’s cover a wide range of use cases including product identification, logistics, inventory management, purchasing and advertising. Use the following instructions to get started:

EAN-13 and UPC-A Barcodes

Create a UPC-A code by entering 12 digit digits (example: 038678561125). Enter the code EAN-13 by entering 13 digits (example: 3033710074365).

EAN-8 Barcode

Create an EAN-8 code by entering an 8 digit (example: 30337100).

QR Code

Create a QR code by entering any text or URL (example: “Hello world” or “”). Note that the URL must start with “http: //” to be recognized internally.

How Do QR Codes Work?

An active QR code is one that a QR code scanner is in a position to easily scan, prompting users to click on external links when scanning. The external link provides relevant information that the user is trying to find.

How to scan QR Code

To scan a QR code on Android and iPhone,

  • Open the camera
  • Point camera to QR code
  • View its content displayed on the smartphone or click on the link to view its content.

To learn how to scan a QR code on an iPhone, read this blog post. To learn more about how to scan QR codes using Android, read the blog post.

The modern QR code may look very generic to the eye but in fact it consists of 7 element parts. Like bar lines and patterns in 2-D barcodes, each part of the QR code serves a specific purpose. Each of them forms a sort of crossword puzzle-like pixel pattern. Exact elements contain information such as direction, time, error tolerance, spaces. Learn more about these elements of a QR code below.

Generate your barcodes

In its simplest form, a barcode is simply an image that represents numbers, text, or both. This image is often read by a scanning device and therefore this information is transmitted to a computer almost immediately.

You have two main options when it involves fixing your small business goods with barcodes. You can either create your own barcode using a barcode font (or a web service like the one from ID Automation) or purchase an existing barcode from a universal database like UPC.

If you are using a barcode system internally, then you are just about to use any barcode type. The most common is known as code 3K 9… You will generate code 3 of 9 barcodes using a web barcode generator or perhaps a barcode font. You will print these on standard label stickers, paste them on your product and set you all up!

If you are a manufacturer and you would like your products sold on Amazon or any major retailer, then you want to insist on 9PCs. You will buy UPC from a reseller or directly from the source, GS1.

The Benefits of Using Barcodes

While barcodes were originally developed to speed up the process of sales and transactions, they are available with many other benefits.

  • Better accuracy

Using barcodes to process a product’s data is far more accurate than manually entering that data to a sales associate, which is susceptible to human error.

  • Real time data

Due to the speed at which knowledge is processed, data about inventory levels or sales are immediately discarded.

  • Training requirements reduction

Thanks to the simple use (just point and click) of barcode scanners, employees do not require much training on how to use one.

  • Better inventory management

With improved accuracy and real-time data, retailers enjoy faster cycle counting and more accurate inventory turnover estimates.

  • Low cost of implementation

Generating barcodes is quick and straightforward, as well as potential savings due to improved transaction speed, as better accuracy of inventory and sales data allows retailers to anticipate subsequent implementations of savings…

How to Read a Barcode?

As explained within the article “What are barcodes” , universal product codes are symbols that are made up of similarities black lines that are found on product packaging, bottles, parcels, if with a “barcode reader” Numeric or alphanumeric code that has been “scanned”.

If you are not conscious of how to read barcodes, then you should know that there are many free solutions that allow you to try to do this in the form of a smartphone app or “PC barcode scanner”.

On this page we will examine how to identify the 2 most commonly used barcodes: the 12-digit UPC (Universal Product Code) and therefore the 13-digit code EAN (European Article Number).

Read Barcode UPC Code

UPC bar codes are typically registered and used in the US and Canada, therefore, do not indicate a rustic identifier.
The UPC Universal Product Code consists of 10 middle numbers, and at the vertex of the code are two numbers, the last being the check number

1. Lines and spaces of Barcode

Barcodes are not just made up of black lines, but white spaces are also important.

2. Different thicknesses

The first thing we see is that the lines can have 4 different thicknesses.

3. Beginning and end of the barcode

Codes begin with code 101 (Fine Line Black - Fine Line White - Fine Line Black)
Road is 01010 in exactly half the code

What information does a barcode hold?

To understand what information is stored on a barcode, you first want to know what a barcode is and the way the barcode works. A barcode is an encoded image, usually displayed with black and white lines of varying widths containing important information easily readable by a machine.

Barcodes store information using symbols that vary from lines to dots, such as within matrix barcoding. There are several types of barcodes, such as one-dimensional and two-dimensional barcodes, which determine the exact type of data that will be encoded.

When the machine fails to read the barcode, the person can enter the barcode number and obtain the necessary knowledge; It is often seen in supermarkets and stores.

Also, knowing what barcode information is stored on the selected code will depend on what kind of object the barcode is printed on. A barcode found on a grocery item will have different data than a barcode on your driver’s license, for example.

Food barcode information usually contains a brief product description that refers to line pricing in many automated checkout systems. Most products that you simply have available for contact on a day to day basis will have encoded information that allows for the store’s checkout system to quickly and easily find and register the goods being purchased, the current price, Modify the number on the database and apply for any existing sales or promotions.
