Wearable scanning reaches a new level of convenience with the M3 MOBILE UNIV-WERS-U20. Unlike bulky handheld scanners that tie up your hands, this finger-worn ring scanner keeps both hands free for picking, sorting, and packing while capturing 1D and 2D barcodes instantly. Its high-performance imager reads even damaged or poorly printed codes, and the omnidirectional scan angle means you never waste time aligning the device. With Bluetooth 5.0, it pairs seamlessly with Android, iOS, and Windows hosts, acting as a keyboard wedge or serial device. The adjustable strap fits any finger size, and the lightweight design (only 20 g) ensures all-day comfort.

Highlights

• Finger-worn ring design frees both hands for maximum productivity
• Reads 1D and 2D barcodes omnidirectionally with a high-performance imager
• Bluetooth 5.0 Low Energy for reliable wireless connectivity up to 10 m
• Rugged IP65 rating: dust-tight and protected against water jets
• Long battery life: up to 10 hours or 15,000 scans per charge
• Supports HID keyboard emulation and SPP serial profile for easy integration
• Vibration, LED, and beeper feedback for confirmation in noisy environments

In daily use

Slip the UNIV-WERS-U20 onto your index finger, tighten the strap, and you're ready to scan. In warehouse picking, it eliminates the constant pick-up-and-put-down of a handheld scanner, reducing fatigue and speeding up workflows. The 250 mAh battery charges in about 2.5 hours and lasts a full shift, so you can keep working without interruption. When you're out of Bluetooth range, the built-in 1 MB memory stores up to 10,000 EAN-13 barcodes in batch mode, syncing later. The scanner survives drops from 1.5 m onto concrete and operates in temperatures from -20°C to 50°C, making it suitable for cold storage and outdoor use. The IP65 rating means dust won't clog the optics and occasional splashes won't cause downtime.
