Generalscan GS R3521 2D Imager Bluetooth Ring Scanner (Zebra SE4107 engine)

The Generalscan R3521 is a Bluetooth ring barcode scanner — a compact, finger-worn 2D scanner, built around the SE4107 scan engine, that pairs to a phone, tablet or wearable computer and leaves both hands free for picking and packing. It reads printed, damaged and on-screen barcodes in a fraction of a second, so warehouse and retail teams keep moving instead of reaching for a handheld gun.

Scan engine — Zebra SE4107 (2D imager)

The Zebra SE4107 is a standard-range 2D imager with strong motion tolerance — it captures 1D and 2D codes quickly while the hand is moving, so pickers keep flowing without pausing to line up each label. We can advise on the right engine for your barcode types, working distances and environment — talk to our team .
