Overview
A shop assistant or stockroom clerk can switch between a cordless radio link and a USB cable on this handheld laser scanner. An indicator shows battery level, and the lithium polymer cell comes in the box.
Dual connection modes mean the scanner can keep working when the battery runs low, simply by plugging in the cable. Battery level is visible at a glance. Wireless distance is not stated, and linear codes are the only type described.
Who it's for
Shopkeepers, inventory staff and office users feeding a desktop or laptop will plug the receiver in and scan. The wired mode helps a dead battery moment. Buyers needing phone screen reading or long range should look elsewhere.
Pros and cons
- Wireless and USB wired modes
- Battery level indicator

- Wireless range not listed
- 1D codes only
- Only desktop and laptop named
Performance notes
A laser sweep reads the bar widths and the scanner sends the result over the chosen link. Wired use draws on the cable, so the battery matters only in wireless mode. The indicator warns before the cell runs flat.
