Barcode Scanner Types: 1D, 2D, Wired and Wireless
Barcode scanners differ by 1D/2D scanning technology, connection type and use case. Learn what to consider when choosing a scanner for your business.
1D Barcode Scanners
Reads traditional linear barcodes. Common in supermarkets, pharmacies and retail. Economical and fast, but only reads linear barcodes, not QR codes.
2D Barcode / QR Scanners
Reads both 1D and 2D codes such as QR/DataMatrix. Required for e-invoice QR codes, mobile payments and pharmaceutical tracking (İTS/DataMatrix). Can read codes from screens, including phone screens.
Wired vs Wireless
Wired scanners are reliable and maintenance-free for fixed checkout points. Wireless (Bluetooth/2.4GHz) models suit warehouses, stocktaking and movement within large stores; consider battery life and range.
Handheld, Fixed and Industrial Models
Handheld scanners are the most common. Fixed hands-free scanners suit high-volume checkouts. Industrial scanners withstand drops, dust and moisture and are designed for production and logistics environments.
Frequently Asked Questions
Which scanner is needed to read an e-invoice QR code?▾
QR/DataMatrix is a 2D code and requires a 2D imager barcode scanner. 1D laser scanners cannot read these codes.
Can I scan a barcode from a phone screen?▾
Yes, but an imager (2D) scanner is required. Laser (1D) scanners cannot read from a lit screen.
