Portable ring scanner for mobile workflows

The Adesso NuScan4300B is a lightweight 2D ring barcode scanner built for warehouse logistics retail and mobile scanning. It reads QR Code PDF417 Data Matrix MicroQR and common 1D barcodes using an advanced CMOS engine. Bluetooth 5.0 and 2.4GHz RF wireless technology connect to iOS Android Windows and MacOS devices up to 50 feet away. The compact design weighs under three ounces for comfortable all-day wear.

Simple pairing with occasional interference

Pairing uses standard Bluetooth 5.0 or the included 2.4GHz RF dongle for plug-and-play setup on supported operating systems. The 12-inch scanning depth and 24-inch per second motion tolerance capture codes quickly even during continuous movement. In crowded RF environments the 2.4GHz band can experience interference so the Bluetooth link is often more stable. The scanner survives drops up to 5 feet reducing downtime from accidental impacts.

Verify host device and barcode requirements

Confirm the host device runs iOS Android Windows or MacOS with Bluetooth 5.0 or an available USB port for the RF receiver. Ensure the barcodes in use are QR Code PDF417 Data Matrix MicroQR or standard 1D symbologies because other 2D formats are not supported. The 12-inch maximum read range suits close-range tasks but will not reach labels mounted farther away. No charging cradle is included so plan for USB charging access during shifts.
