Barcode Scanner Types: 1D, 2D, Corded, 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 best barcode scanner for your business.
1D Barcode Scanners
Reads traditional linear barcodes. Common in supermarkets, pharmacies, and retail. It's economical and fast, but can only read horizontal line barcodes and not QR/square codes.
2D Barcode / QR Readers
Reads both 1D and 2D codes like QR/DataMatrix. Essential for e-invoice QR codes, mobile payments, and pharmaceutical tracking (ITS/QR code) applications. Capable of reading from screens (e.g., phone screens).
Wired vs. Wireless
Wired scanners are reliable and maintenance-free for fixed checkout points. Wireless (Bluetooth/2.4GHz) models are ideal for warehouse, inventory, and large in-store mobility, but battery life and range should be considered.
Handheld, Fixed, and Industrial Models
Handheld scanners are the most common. Fixed (hands-free) scanners are suitable for high-volume checkout points. Industrial scanners are resistant to drops, dust, and moisture, and are designed for manufacturing and logistics environments.
Frequently Asked Questions
What kind of scanner do I need to read the e-invoice QR code?▾
A QR/DataMatrix code is a 2D code; therefore, a 2D (imager) barcode reader is required. 1D laser readers cannot read QR codes.
Can I scan the barcode on the the phone screen?▾
Yes, but this requires an imager (2D) type scanner. Laser (1D) scanners cannot read from a glowing screen.
