Description
The Newland WD4 Ring Scanner is a small wearable barcode scanner that sits on a finger, so workers can scan while carrying boxes or handling stock. The trigger button is pressed with the thumb, which keeps both hands free for the job.
It reads a wide range of 1D and 2D symbologies with a 640 x 480 CMOS imager, red LED aiming and white LED illumination. Scans are sent wirelessly over Bluetooth 5.0 to Android, iOS and Windows devices.
Hands-free scanning on either hand
The head rotates, so the WD4 fits the left or the right hand. Supported 2D codes include PDF417, QR Code, Data Matrix, Aztec, Micro PDF and Micro QR. Newland lists a depth of field of 55 mm to 145 mm for Code 39 (5 mil) and 30 mm to 195 mm for QR (15 mil).
Wireless connection and offline memory
Bluetooth 5.0 reaches up to 40 m in a wide empty area. The scanner pairs with Android mobile computers, tablets, PCs and smartphones, and with iOS and Windows devices through EasyConnect. 1MB of memory holds more than 16,000 EAN 13 codes, so it can also collect data offline, and EasySet software configures it.
Battery, charging and feedback
A 4.35 V, 670 mAh Li-ion battery is rated for up to 8 hours depending on how intensively you scan, with a charge time of less than 2 hours. Charging uses the supplied USB-A to magnetic connector cable, or an optional 2-slot cradle that can be daisy-chained up to 4 cradles for 8 scanners. A buzzer, LED and vibration confirm good reads.
