9 Best Shopify Barcode Scanner Apps 2025

How Do Barcodes Actually Work?

Barcodes are those little black-and-white stripes you see on almost every product you buy. They might look like just a bunch of lines, but they’re actually a super handy way to store information that can be read quickly by a scanner. Here’s how they work in a way that’s easy to understand:

1. What’s a Barcode?

• Visual Code: A barcode is basically a visual code made up of lines (bars) and spaces. Each combination of bars and spaces stands for a specific number or letter. The most common types of barcodes you’ll see in stores are UPC (Universal Product Code) and EAN (European Article Number).
• Information Encoded: Think of each barcode as a secret message that holds information like the product’s ID, which a computer can understand when it’s scanned.

2. How Does a Barcode Store Information?

• Patterns of Lines: The width of the bars and the spaces between them represent different numbers. For example, a group of lines might stand for the number “7” while another group stands for “3.”
• Check Digit: Some barcodes also have a special digit called a “check digit.” This is used to make sure the barcode was read correctly by the scanner.

3. How Does a Scanner Read a Barcode?

• Light and Reflection: A barcode scanner shines a light on the barcode. The black bars absorb the light, while the white spaces reflect it back.
• Decoding the Pattern: The scanner picks up the pattern of reflected light and dark bars and translates it into the numbers or letters the barcode represents.
• Instant Data: Once the barcode is read, the scanner sends the information to a computer system. For example, at a checkout, it tells the system what product you’re buying and its price.

4. Why Are Barcodes Useful?

• Fast and Accurate: Scanning a barcode is much faster and more accurate than typing in numbers by hand. This is why cashiers can quickly ring up your purchases.
• Inventory Management: Barcodes also help businesses keep track of their stock. Every time an item is scanned, the system updates how many are left in the inventory.

5. Different Types of Barcodes

• 1D Barcodes: These are the traditional barcodes with just lines and spaces. They’re great for storing things like product IDs.
• 2D Barcodes: You might know these as QR codes. They can store a lot more information, including web links, and are read in both directions—horizontally and vertically.

6. Why Barcodes Are Everywhere

• Convenience: Barcodes make shopping quicker and inventory management easier. They’re cheap to produce and incredibly efficient.
• Versatile: From tracking packages to checking out groceries, barcodes are used in so many ways that help businesses run smoothly.

In a nutshell, barcodes are a simple but genius way of storing and reading information quickly. The next time you see a cashier scan a barcode, you’ll know that those little stripes are doing some pretty important work!

How Were Barcodes Invented?

The story of how barcodes were invented is pretty cool, and it all started with a simple need: speeding up the checkout line. Back in the late 1940s, grocery stores were getting busier, and cashiers had to manually punch in prices for every single item. This process was slow and often led to mistakes. Store owners were desperate for a faster way to handle all those customers and keep track of inventory.

Enter Norman Joseph Woodland, a bright grad student at Drexel University. Woodland was inspired by Morse code—you know, the dots and dashes used in telegraphs. He figured if dots and dashes could communicate information, maybe lines could do the same thing. So, he teamed up with his buddy Bernard Silver to create the first barcode design. But instead of the rectangular barcodes we see today, their initial design was a circular one that looked like a bullseye. The idea was that a circular code could be scanned from any direction, which was pretty forward-thinking for the time.

In 1952, they got a patent for their idea, but there was a catch: the technology needed to actually scan these codes didn’t exist yet. So, their invention sat on the shelf for about 20 years until technology caught up. Fast forward to the early 1970s, and the retail industry was looking for a way to automate checkout processes. That’s when the Universal Product Code (UPC) was born—a more practical, rectangular barcode that could easily be printed on products and scanned at the register.

The big moment came on June 26, 1974, when the very first barcode was scanned at a supermarket in Troy, Ohio. The item? A pack of Wrigley’s Juicy Fruit gum. This simple act marked the beginning of a new era in retail, and barcodes quickly became the go-to method for tracking products, managing inventory, and speeding up checkout lines.

Today, barcodes are everywhere, from groceries to packages and beyond. They might seem simple, but they’ve completely changed how businesses operate—all thanks to a grad student who thought, “What if we could use lines like Morse code?”

What Kinds of Barcodes Are There?

1. 1D Barcodes (One-Dimensional)

• UPC (Universal Product Code): Probably the most familiar, UPC barcodes are used mainly in retail to identify products. They’re made up of 12 digits and are great for tracking inventory.
• EAN (European Article Number): Similar to UPC, EAN barcodes are used worldwide and typically have 13 digits. They’re common on products sold internationally.
• Code 39: This barcode can encode both numbers and letters, making it versatile for things like name tags, inventory labels, and more. It’s often used in military and automotive industries.
• Code 128: Known for its high data density, Code 128 is used in logistics and transportation for tracking shipments and pallets. It can encode all 128 ASCII characters.
• ITF-14: This barcode is used for packaging, especially in shipping. It’s often printed on cartons and boxes that contain multiple units of a product.

2. 2D Barcodes (Two-Dimensional)

• QR Code (Quick Response Code): QR codes are square barcodes that can store a lot of information, including URLs, text, and contact details. They’re popular in marketing, ticketing, and mobile payments because they can be easily scanned with a smartphone.
• Data Matrix: This small, square barcode is often used in manufacturing and healthcare to mark small items, like electronic components or medical devices. It’s highly reliable for tracking items even in tough environments.
• PDF417: A stacked linear barcode that can encode large amounts of data, including photos and fingerprints. It’s commonly used on identification cards and in shipping labels.
• Aztec Code: Often found on train tickets and airline boarding passes, the Aztec Code is compact and can be scanned even if it’s partially damaged.

3. Specialty Barcodes

• MaxiCode: Developed by UPS, this barcode is used for tracking packages during shipment. It looks like a bullseye with dots around it and is designed to be read quickly by scanners.
• Codabar: This barcode is often used in libraries, blood banks, and photo labs. It’s easy to print and scan, making it suitable for applications where simplicity is key.

4. GS1 DataBar

• DataBar: This barcode can hold more information in a smaller space than a traditional UPC, making it useful for identifying small items like fresh produce. It’s also capable of encoding additional data like expiration dates.

5. Postnet/Intelligent Mail Barcode

• Postnet/Intelligent Mail: Used by the U.S. Postal Service, these barcodes encode postal routing information to automate mail sorting and delivery.

Key Differences Between 1D and 2D Barcodes:

• 1D Barcodes: Are linear and only hold a limited amount of data, usually numeric or alphanumeric. They require more space to encode more data.
• 2D Barcodes: Are two-dimensional and can hold much more data in a smaller space. They can store not only numbers and letters but also URLs, images, and more complex data. They’re also more resistant to damage.
