Barcodes are everywhere. They're on books, clothes, and even cereal boxes.
Some people don't realize just how important a barcode can be in the modern world of business, but those who do know that they are a critical part of the retail industry—and one that will only become more ubiquitous as time goes on.
If you're unfamiliar with barcodes or want to learn more about them for your own use, this article will help you get started!
What is a barcode?
A barcode is a series of lines and spaces that represent numbers. Barcodes are used to identify products, services, and other assets.
The bar codes are read by a barcode scanner, which converts the code into the corresponding number.
How do barcodes work?
Barcodes are a type of machine-readable code that a barcode scanner or smartphone camera can read.
If you're unfamiliar with how these work, here's a brief overview: A barcode is essentially a pattern of lines—usually black bars and white spaces—that represent data.
When the barcode is scanned with a device like a smartphone or traditional barcode scanner, the data encoded in this pattern is sent to a computer program where it's decoded into something meaningful (like an item description).
Barcodes can even be read by an optical character recognition (OCR) system like those used by banks and government agencies.
Every barcode has four components, usually arranged in an easily recognizable pattern:
- Quiet zone: This is the area between the start and stops markers. It does not contain any data, but it must be present for the machine to be able to read it.
- Number system digit (NSD): The first character in a UPC code is always '0' or '1'.
- Manufacturer code: This code represents which company made that particular product and differentiates manufacturers from each other within a single product type (e.g., "00" might represent one company while "04" might represent another). In some countries, this also includes information about where the product was manufactured—for example, if a company builds products abroad but sells them domestically under its own brand name rather than licensing someone else's name out on those same products. They would use an 'X' instead of an actual country code here because they're not actually allowed by law to print that kind of detail directly onto their labels without getting permission from whoever owns that particular trademark/branding rights first!
- Product code/barcode number (PCN): This part identifies exactly which type of item has been scanned so that companies can better keep track of inventory levels where needed; there are different versions depending on whether or not your business needs something more granular than just simple SKUs."
Types of Barcodes
Once you have a basic understanding of barcodes and how they work, it's important to know the different types of barcodes.
One type is better suited to your needs than another. The two main types of barcodes are linear and matrix.
- Linear/1D: This type works by breaking down information into vertical stripes of various lengths and widths (also called bars). These stripes are then read by an optical scanner, allowing the machine to decode them into machine-readable data.
- Matrix/2D: This type utilizes two-dimensional symbologies or shapes representing characters out of a set number of possible characters (such as uppercase letters or numbers). These symbols are usually square but can also be rectangular in shape.
Common Product Codes
UPC-A is the original product code system which IBM developed in 1973. It uses a 12-digit number to identify a single product. UPC-E is another form of UPC that's used for smaller items like books and magazines.
EAN-13 and EAN-8 are standardized variants of the 13-digit and 8-digit codes, with some additional data fields added to them; they're mostly used in Europe and Asia, respectively.
ISSN (International Standard Serial Number) is an identifying number that's assigned to each issue of a serial publication such as a newspaper or magazine.
Code 39 uses six bars to represent numbers 0 through 9 plus + (plus), - (minus), / (slash), and blank spaces; it can encode 26 = 64 characters—enough for English letters or digits plus some common punctuation marks or symbols such as !@#$%&*()_+-.
Code 128 can encode all 95 printable ASCII characters from 0x00 to 0x7F (including space) using only two bytes per character so that it can use up less storage space than other barcode types.
What are the benefits of using barcodes?
- Accurate data collection: Accurate data collection is one of the main benefits of barcodes. Barcodes are a quick, efficient way to get information on products. This can be very useful for inventory management or tracking items that have been sold in an online store.
- Reduced costs and improved customer service: Because barcodes require less manual labour than other systems, they save businesses time and money over time—which means you'll have more resources for other important things like hiring more employees or expanding your company's reach into new markets!
- Improved inventory management: Because barcodes allow for more accurate tracking of products throughout their lifecycle (as well as between different companies), companies can better anticipate demand based on historical sales data, which helps them plan ahead, so they don't end up with too much stock being produced at once or not enough when needed most urgently by customers who want fresh supplies quickly instead waiting weeks until next shipment arrives at home depot store near me."
Where can I use barcodes?
Barcodes can be used in many different industries and applications. In fact, barcodes have been widely used since the 1960s. The most common uses of barcodes include:
- Supply chain management
- Healthcare management (e.g., patient IDs)
- Manufacturing processes (e.g., assembly line tracking)
- Retail checkout lanes (e.g., price lookup)
- Shipping and logistics
How to create a barcode?
There are a few options if you're looking to create barcodes for the first time.
You can use one of the many free barcode generator tools available online or buy a barcode scanner at an office supply store and scan existing barcodes.
How Barcodes Help Business
A barcode is a machine-readable label that a computer or an optical scanner can scan.
The logo consists of parallel lines and spaces between them, which represent the data encoded in the barcode.
Barcodes are used in many different industries, including retail and financial services; they help businesses to manage inventory by reducing human error and speeding up processing times.
They also ensure consistency across all product categories, making it easier for customers to find what they want when shopping at stores with multiple locations nearby (such as grocery stores).
Barcodes are also used to track products being shipped around the world. This allows businesses like Amazon Prime Now or Uber Eats to track their supply chains efficiently so that orders arrive on time without getting lost along the way!
History of Barcodes
The world of barcode technology began in the 1960s when it was still referred to as "barcode" or "UPC." Supermarket industry workers used the first barcode to scan and identify products that were scanned at the checkout counter.
Over time, this technology has evolved significantly and is now used in many industries around the world.
In 1976, a French engineer named Claude Elwood Shannon published an article titled "A Mathematical Theory of Communication," which outlined how digital communication systems work.
His research explains how information can be stored in binary form and then transmitted over a channel (such as fibre optic cables).
This concept became known as Shannon's Rule, which has formed the basis for modern-day data storage systems such as CDs/DVDs or computer hard drives.
Barcodes are a critical technology in inventory management.
They are used to track the movement of goods and identify products. The codes can be printed on labels or attached to products, allowing machines to quickly scan them and read the information encoded by that barcode.
The data is then sent over a radio signal or other connection for processing. Using this technology, companies are able to see how many items they have in their warehouses and determine when it's time for restocking.
Barcodes also make it easier for store employees to perform price checks, verify returns, find missing items and more.

FAQ's Related to The Purpose of a barcode
1. What is the difference between a barcode and a QR code?
A barcode is essentially a series of numbers printed in black on an item or packaging. The pattern of bars and spaces is recognized by scanning equipment, allowing them to be identified. A QR code (Quick Response Code) is similar. Still, it uses both black "data" elements as well as coloured "error correction" elements which allow for higher-density information storage than traditional linear barcodes.
2. What is the difference between RFID and Barcodes?
Radio Frequency Identification (RFID) uses radio waves to track items like tractors or pallets with sensors attached directly to them; however, these systems require expensive readers that transmit signals through walls instead of just being able to scan from an angle like you can with a barcode scanner. In contrast, using an iPhone app like Red Laser recognizes any UPC-based tag from afar without needing special equipment at all! It's easy enough for anyone with a smartphone camera—and it works indoors too!
