Pick-to-Light order picking technology utilizes light to direct a user to find an item quickly. Used in warehouse fulfillment operations, pick-to-light improves both speed and accuracy when picking. This occurs by eliminating the paper order resulting in fewer potential errors and a faster pick rate. Pick-to-light systems can be located on carousels, carton flow rack, shelving storage, static shelving and batch picking carts, etc. to indicate which items and quantities to pick. The light goes off by pushing a button to confirm each pick.
