U3
The U3 is the slim-body 1D laser scanner of the U series — a narrower grip on the same laser engine, for teams that scan with gloves on or hand the gun around all shift long.

Staffed at the edges, scanned at the counter.
Unmanned stores are staffed nowhere and everywhere: one support person walks the floor, rescues a stuck self-checkout, and mans the small service counter where membership cards and return items land. That person needs a scanner that handles both paper label and ID card work without wearing the arm out by closing time:
- Rescue duty in one hand — the slim grip keeps the gun usable pinched between fingers while the other hand holds the basket or the return form.
- Labels on the move — shelf audits and restock checks read at the 4 mil class, which covers the mini label strips stores print for the first and last shelf meters.
- One cable, all shifts — USB HID plugs into the counter PC; the same unit works at the self-checkout diagnostics port the moment a jam is reported.
Same bracket, same line
U3 FAQs
Yes — the slim-body variant reduces grip diameter while keeping the same laser engine and 4 mil class; order one sample and let your shift staff vote before the fleet order.
Yes — RS232 mode makes it a service tool for the diagnostics ports on kiosk hardware; the free SDK documents the command set for the FAE to check against your kiosk brand.
MOQ 1 pc means you can hold a cold spare cheaply; the 2-year warranty and 48h FAE line cover the rest.
