Pick station operators are directed by a flat screen information display of an image of the item to pick and quantity required for each order. An integrated weigh scale at the pick location (optional) checks expected weights, further enhancing accuracy and ensuring that any errors are identified and corrected on the spot. Recognized as one of the most effective methods for increasing productivity and accuracy in picking operations, voice technology features hands-free, eyes-free operation. Operators wear a portable belt-mounted voice terminal and headset. Workers hear instructions and perform tasks without having to look down at a handheld computer screen display or sort through paper lists. The pick-to-light system uses a combination of display units to point operators to specific stock locations. Typically, each SKU has a display with a light, an acknowledgement button, and a digital readout to indicate quantity. Pick-to-light systems in reverse, put-to-light displays point the operator to locations requiring an item to be put, rather than picked. The operator scans an item—either a piece or a case—and then individual displays point out which containers require that item. A display unit at each container location shows how many of the item that container requires. The operator uses an acknowledgement button to confirm each put. Picking staff can be directed to each assignment using handheld RF devices. The operator scans the barcode or UPC code and then performs the order picking tasks. For hands-free scanning, pickers wear a wrist mounted computer with a ring scanner, which enables the pickers to have both hands available for picking products.
