What is a Handheld Barcode Scanner?
A handheld barcode scanner is a compact electronic device that reads barcodes—those black-and-white lines you see on almost every product.
How It Works
The scanner shines a light on the barcode. It then reads the reflection using sensors and decodes the information, sending it to a connected device like a PC, POS terminal, or mobile app.
Types of Handheld Barcode Scanners
Corded Scanners
- Connect via USB or serial port.
- Reliable and ideal for fixed locations.
Cordless Scanners
- Connect via Bluetooth or Wi-Fi.
- Great for mobility (warehouses, outdoor use).
1D Scanners (Linear Barcodes)
- Only read barcodes with horizontal lines (e.g., UPC codes).
2D Scanners (QR Codes, DataMatrix)
- Read barcodes from any angle or shape.
Laser vs. CCD Scanners
- Laser: High precision and distance.
- CCD: Close-range and rugged environments.
Expert Tip:
“For retail, a corded 2D scanner is best. For logistics, go cordless with industrial durability.”
