Pick-to-Light System

When Pick-to-Light is applied to the order picking environment, it enables an order picker to quickly and easy find the correct location by means of lights and LED display. Each tag represents a product in the storage location.

Besides guiding the picker to the exact location, the lights also display the precise amount ordered and requires confirmation while each item is picked.

Put-to-Light System

Put-to-Light usually applies to the batch picking environment. It functions as Pick-to-Light in reserve. Once the items for the orders are batch picked in the warehouse and brought the Put-to-Light System. The picker will scan/input an item and all the locations that need that item will illuminate. The picker will distribute the item to each location and turn off the light.
