What is a pick-to-light system and how does it work?
A pick-to-light system is a paperless picking method that places a light module with a numeric display and confirm button at each storage location, so lights guide operators to the right item and quantity. With Addverb's Rapido, scanning an order crate's barcode lights the relevant modules, each display shows how many units to pick, and the operator presses the button to confirm. The same hardware supports picking, sorting and kitting. -
What is the difference between pick-to-light and put-to-light?
Pick-to-light tells operators which location to take items from and how many, while put-to-light tells them which order container or slot to place items into, typically at a sorting or consolidation wall. Addverb's Rapido modules handle both, so the same hardware can guide picking in storage zones and order sortation at put walls. Many sites combine the two, picking in batches and then putting to orders. -
Should I choose pick-to-light, voice picking or RF scanning?
Choose pick-to-light for dense, high-velocity pick zones where operators handle many lines in a small area, voice picking for case or pallet picking across large areas with hands-free work, and RF scanning for mixed, low-volume or changing environments. Pick-to-light removes searching and needs very little training. -
How does pick-to-light reduce picking errors?
Pick-to-light reduces picking errors by lighting only the correct location, showing the exact quantity on a display, and requiring the operator to press a confirm button before the next pick is released. Addverb's Rapido modules use four alphanumeric digits and seven LED colours, so several operators or orders can work in the same zone, each following their own colour. Every confirmation is recorded, which gives real-time pick visibility. -
How is a pick-to-light system installed and connected?
Addverb's Rapido pick-to-light modules mount directly on existing shelving or flow racks and run on 24 V DC using power line communication, so data and power share the same cable in a multidrop layout. Each compact module measures 124.6 x 53.9 x 16 mm and carries CE certification. Rapido connects to your warehouse management or execution system, which sends pick tasks and receives confirmations.
