Introducing Zebra's RS4000 1D Ring Scanner, a powerful hands-free 1D scanner for Zebra's leading edge WT6000 Wearable Mobile Computer. When you put the small and lightweight RS4000 1D Ring Scanner on the fingers of workers who are using Zebra's WT6000, your workers are free to keep their hands and eyes on the items they are handling. This allows for an increase in worker productivity. The easy-to-use scan line ensures easy aiming for first-time capture of barcodes in virutally any lighting condition. The RS4000 can easily switch from right to left handed operation and the areas of the cable most vulnerable to wear and tear are protected to keep the device looking like new. The RS4000 draws very little power from the wearable mobile computer, preserving plenty of power for full shift operation on a single charge.
