1D vs. 2D Barcode Scanners
What's the Difference?
Not all barcode scanners read the same types of codes. Understanding the difference between 1D laser scanners, 1D linear imagers, and 2D area imagers can help you choose scanning technology that fits your workflow, environment, and business needs.
Explore the capabilities of each scanner type, compare their features, and find the right solution for your operation.
One Barcode. Different Ways to Read It.
Barcodes generally fall into two categories: one-dimensional (1D) and two-dimensional (2D). Each uses a different format to store information, and the scanner you choose determines which barcode types your business can capture.
1D barcodes use a series of parallel lines and spaces to encode data. Common examples include Code 128 and Code 39.
2D barcodes use patterns of elements arranged horizontally and vertically, allowing them to store more information in a compact space. Common examples include QR Codes and PDF417.
Three Scanner Technologies to Know
From traditional laser scanning to advanced area imaging, each technology offers different capabilities for reading barcodes in your operation.
1D Laser Scanners
Traditional 1D laser scanners read linear barcodes by emitting a laser beam and detecting the reflected light. They are commonly used for straightforward barcode scanning applications where 1D codes are the primary requirement.
- Designed to read traditional 1D barcodes
- Often an economical option for basic scanning
- Requires the laser to pass across the barcode
- Performance can be affected by damaged or poor-quality labels
1D Linear Imagers
1D linear imagers use image-sensor technology to capture and decode linear barcodes. Instead of relying on a laser beam, they take an image of the barcode, which can help them read certain damaged, faded, or less-than-perfect labels.
- Reads traditional 1D barcodes
- Uses image-based scanning technology
- Can read some damaged or poorly printed 1D codes
- Useful for retail, warehousing, and inventory workflows
2D Barcode Scanners
2D barcode scanners, also called 2D area imagers, capture an image of the barcode and decode information from it. They can read both 1D and 2D codes, including QR Codes, Data Matrix, and PDF417.
Many 2D scanners can read barcodes from different orientations and from digital displays, such as mobile phone screens. This versatility makes them useful for workflows that require flexibility beyond traditional linear barcode scanning.
- Reads both 1D and 2D barcode formats
- Supports omnidirectional scanning
- Can read compatible barcodes from screens
- Suitable for applications requiring broader barcode compatibility

| Feature | 1D Laser Scanners | 1D Linear Imagers | 2D Barcode Scanners |
|---|---|---|---|
| Barcode Types Supported | 1D barcodes | 1D barcodes | 1D and 2D barcodes |
| Scanning Technology | Laser-based | Image-based | Area imaging |
| Scanning Orientation | Requires alignment with barcode | Can read 1D barcodes from various angles | Omnidirectional scanning |
| Damaged Barcode Reading | Performance may be affected | Can read some damaged or faded 1D codes | Can read some damaged codes, depending on condition and model |
| Common Applications | Retail checkout, basic inventory | Warehousing, logistics, asset tracking | Healthcare, shipping, mobile payments, kiosks |
| Relative Cost | Often a lower-cost option | Varies by model and features | Varies; offers broader barcode compatibility |
| Mobility Options | Wired and select cordless models | Wired and cordless options | Wired, cordless, and mobile computer options |
Which Barcode Scanner Is Right for You?
If your workflow relies exclusively on traditional 1D barcodes, a laser scanner or linear imager may meet your needs. If your business scans QR Codes, needs to capture barcodes from screens, or requires greater barcode flexibility, a 2D area imager may be worth considering.
The right choice depends on your barcode types, scanning environment, workflow, and future requirements.
