Barcode Scanner Types: 1D, 2D, Wired, and Wireless
Barcode scanners vary based on 1D/2D reading technology, connection type, and usage scenario. Here's what you need to know to choose the barcode scanner best suited to your business.
1D Barcode Scanners
Reads traditional linear barcodes. Widely used in supermarkets, pharmacies, and retail settings. Economical and fast; however, it only reads horizontal line barcodes and cannot read QR/square codes.
2D Barcode / QR Code Scanners
It reads both 1D barcodes and 2D codes such as QR/DataMatrix. It is required for e-Invoice QR codes, mobile payment, and pharmaceutical tracking (ITS/QR code) applications. It also has the ability to scan directly from a screen (such as a phone screen).
Wired vs Wireless
Wired scanners are reliable and maintenance-free for fixed checkout points. Wireless (Bluetooth/2.4GHz) models are ideal for warehouses, inventory counts, and extensive in-store mobility; battery life and range should be taken into consideration.
Hand-Held, Fixed, and Industrial Models
Handheld readers are the most common. Fixed (hands-free) readers are suitable for high-volume checkout points. Industrial readers are drop/dust/moisture resistant and designed for manufacturing/logistics environments.
Frequently Asked Questions
To scan the e-Invoice QR code, which reader do you need?▾
QR Code (QR/DataMatrix) is a 2D code; a 2D (imager) barcode scanner is required. 1D laser scanners cannot read QR codes.
Can I scan a barcode displayed on my phone screen?▾
Yes, but this requires an imager (2D) type reader. Laser (1D) readers cannot read from a glossy/reflective screen.
