Key Differences Between 1D and 2D Barcode Scanners

Choosing between 1D and 2D barcode scanners starts with knowing their key differences. Let’s get straight to it.

First, they differ in form and design.

1D barcode scanners typically use laser scanning technology and have a simpler internal structure. They are compact and often designed in a rectangular or elongated shape, making them ideal for quickly reading linear barcodes arranged horizontally. In contrast, 2D barcode scanners use image-based technology, incorporating cameras or image sensors to decode more complex patterns such as QR codes. As a result, they tend to be slightly larger and are usually designed with a more square-like form factor to accommodate the additional imaging components.

Next, consider the scanning technology.

1D scanners use laser beams or linear imaging to read barcodes by scanning a single horizontal line. 2D scanners use imaging sensors to capture the entire barcode at once, similar to taking a photo.

Barcode compatibility is another major difference.

1D scanners can only read linear barcodes like UPC or Code 128. These codes store basic information such as product numbers. However, 2D scanners can handle both 1D barcodes and 2D codes like QR codes and Data Matrix. They also have a key advantage—you can scan digital barcodes directly from screens or mobile phones, something most laser-based 1D scanners cannot do,e.g. UPC or Code 128.

Data capacity also sets them apart.

1D barcodes store limited data, usually short strings of numbers or letters. 2D barcodes can hold far more information, including web links, customer data, and tracking details.

When it comes to scanning performance, 2D scanners clearly lead.

They can read barcodes from any angle, whether horizontal or vertical. 2D models also support long-range scanning—ranging from just a few inches to many feet away—making them ideal for high shelves or distant items. 1D scanners usually require close-range alignment and clear barcodes for accurate scanning.

Finally, let's talk about cost.

1D barcode scanners are typically less expensive and easier to integrate with basic systems like retail POS. 2D scanners, while more costly, deliver greater flexibility and advanced functionality, making them a better long-term investment for complex operations.

In short, 1D scanners focus on simplicity, speed, and affordability for basic needs. 2D scanners offer greater versatility, advanced features, and higher performance across industries.

If you prefer a quick side-by-side view, here’s a simple comparison table to help you see the key differences between 1D and 2D barcode scanners at a glance.
