1D vs 2D Barcode Scanner: Differences & How to Choose
The short answer: 1D vs 2D barcode scanners
A 1D barcode scanner is designed for linear, one-dimensional barcodes—the familiar lines printed on many retail products. A 2D barcode scanner reads those 1D codes and can also read two-dimensional codes such as QR codes. If your business needs to scan QR codes, screen-based codes or both barcode types, start by checking a 2D scanner's published specifications.
The best choice is not automatically the most expensive scanner. It is the model that reads the codes used in your stock and works reliably with the counter, connection and POS software you use.
What 1D and 2D refer to
1D barcodes store information along one direction and are commonly used for product identification. 2D codes store information across two directions; QR codes are a familiar example. A 2D scanner can be useful when customers, suppliers or your internal workflow present codes on a phone or another screen, but compatibility should still be confirmed for the specific software and use case.
- 1D: linear product barcodes
- 2D: QR codes and other two-dimensional codes
- Check whether codes are printed, shown on a screen, or both
Choose by scanning position
Handheld scanners suit staff-led scanning where items are brought to the counter. Desktop scanners can suit a fixed counter position and a repeatable presentation workflow. Wireless scanning can be useful where the operator needs more freedom of movement, provided the connection, charging process and intended POS setup are suitable.
For a busy counter, also consider where the scanner will sit, the distance from the terminal, and whether staff need to scan larger or awkward items. These practical details affect day-to-day speed as much as barcode type.
Confirm before buying
Do not choose based only on price or the word barcode. Confirm the barcode symbologies, connection method, operating system and POS-software compatibility. Test or confirm how the scanner will enter data into the software if the workflow has any special requirements.

Frequently asked questions
What is the difference between a 1D and 2D barcode scanner?
A 1D scanner reads linear barcodes. A 2D scanner can read 1D barcodes as well as two-dimensional codes such as QR codes. Confirm the supported symbologies in the model specifications before purchase.
Can a 2D barcode scanner read normal product barcodes?
A 2D scanner commonly reads both 1D and 2D barcode types, but the published specifications for the individual model should be checked before ordering.
Do I need a 2D scanner for QR codes?
A 2D-capable scanner is normally required for QR codes. Confirm the code type, whether it is printed or displayed on a screen, and the scanner's specifications for your workflow.
Which barcode scanner is best for a POS counter?
Choose based on the codes you scan, counter layout, connection method and POS software. Handheld, desktop and wireless models suit different workflows; BISON can help confirm the requirements before purchase.
