Choose pick-to-light for a defined picking zone when the operation can justify installed displays, their software connection and maintenance at those pick faces. Choose RF handheld picking when workers must follow changing locations or handle a broad, slower-moving assortment with the same mobile device. A mixed operation may need both. Here RF handheld means a network-connected mobile computer used for warehouse tasks; it does not mean an RFID reader. Neither method, by itself, proves that the right item and quantity reached the right order record.
This is a buying decision for a warehouse operations lead, WMS owner and hardware buyer comparing an installed light-directed zone with worker-carried barcode computers. The existing barcode picking-verification guide explains how a scan can confirm location, item and tote. This guide decides where the direction and confirmation equipment should live, which system components must be quoted, and which exceptions prevent an attractive pick demonstration from becoming a usable purchase.
Buy for the order profile, not the demo aisle
Start with recent order lines, the locations they touched and how often those locations changed. A concentrated pick zone with stable faces may justify lights at the locations where workers repeatedly pick. A long tail of slow-moving stock or frequent re-slotting may favor instructions on a mobile computer that travels with the worker. Do not equate “fast moving” with an automatic pick-to-light verdict: the number of active faces, space for displays, replenishment, labor routes and software change work still determine the installed cost.
Dematic’s case and piece picking overview says its application engineers use SKU velocity, lines per order and channel/timing to choose a pick system. It separately describes typical pick-to-light displays at stock locations, RF-device-directed assignments and put-to-light at destination containers. Honeywell’s order-picking technology page presents light, mobile cart, voice and RF handheld paths that can be combined. Those are supplier-specific offerings and selection cues, not measured results for this warehouse or AIDC GO equipment.
Compare complete quotes, not a light against a handheld
Ask each bidder to mark the boundary between its equipment, the WMS or execution software, site installation and ongoing support. An RF quote needs the exact handheld, scanner and input arrangement, application version, network access, charging and spare devices. A light-zone quote needs the displays and controllers, installation and power or communications arrangement, location mapping, software interface, spare modules and a documented method for re-slotting. Neither list implies that AIDC GO sells pick-to-light equipment or warehouse software.
| Decision | Light-directed zone | RF handheld route |
|---|---|---|
| Where direction appears | Light-directed zone: At the installed pick face; quote the actual faces, displays and controller path. | RF handheld route: On the worker’s device; quote its screen, scan/input arrangement and network coverage along the route. |
| When locations change | Light-directed zone: Show how the location-to-display map, physical layout and software assignment are changed. | RF handheld route: Show how updated locations and tasks reach the device and how the worker confirms the physical location. |
| When a component fails | Light-directed zone: Show whether an individual display or controller can be replaced and how work is safely rerouted meanwhile. | RF handheld route: Show a ready spare, application sign-in and how an uncertain pick is resolved before the task continues. |
| What closes the pick | Light-directed zone: Specify what a light-button acknowledgement means, and whether an item or tote scan is additionally required. | RF handheld route: Specify which scan or input becomes an accepted WMS event; a decode beep is not a completed pick. |
Installed light and mobile capture are not mutually exclusive. For example, lights can direct work in a compact high-activity area while an RF handheld serves reserve stock and exceptions. If a proposal combines them, obtain one transaction ownership rule: which action advances the order, and what happens when a worker uses the other interface for the same task? Do not purchase two confirmation paths that can both post the same quantity without a duplicate-control design.
Keep pick-to-light separate from put-to-light
Pick-to-light directs a worker to a stock location. Put-to-light directs a worker to a destination container after goods are presented. In Dematic’s described put-to-light workflow, an item is scanned and displays identify the destination containers and quantities. That is not a synonym for installing lights on every stock shelf. A bid for order consolidation, batch sortation or a put wall must therefore identify where the item is first identified, how the destination order is selected and what acknowledgement closes the put.
If the buying problem is only whether a handheld confirms the correct pick location, item and order tote, improve that workflow using the existing verification guide; do not treat a new light system as the default remedy. The voice-picking guide covers another hands-free direction path, including headset and application acknowledgement. Comparing voice, light and RF may be useful, but each needs its own complete system boundary.
Make exceptions visible before accepting a quote
Run a short scenario using the buyer’s real WMS rules and representative items. This is a proposed evaluation, not an AIDC GO customer case or measured throughput claim. Give the worker one ordinary line, one short pick, a face that was re-slotted, and an item whose barcode or display cannot be used. For each method, observe how the worker knows the current order and quantity, records a short pick, reaches an alternate location, and sees whether the WMS accepted the event.
A light-button press may acknowledge a location without proving the item’s identity. A handheld scan may identify an item while the wrong tote is active. Decide which events require a location, item or container scan in the configured workflow; then compare the accepted server record, not only the display or scanner feedback. The scan-feedback guide develops the distinction between a decode and application acceptance. If wireless service or a controller fails during an ambiguous task, pause or recover under the WMS owner’s documented rule rather than silently repeating a quantity.
A candidate fails the purchase test when required exceptions have no usable path, a re-slot changes the physical face but not its system mapping, a device substitution loses the approved application/input behavior, or the two proposed confirmation methods can create duplicate events. If both candidate paths work, compare their complete installation, retraining, support and expansion costs against the actual order profile rather than importing a vendor’s headline productivity claim.
Route the enquiry to the correct supplier
AIDC GO’s rugged handheld-terminal range is a hardware discussion starting point for an RF route, not a promise that a named model, WMS client or scanner configuration is approved for this warehouse. Use the mobile barcode workflow page and Integration & Support to explain the application, labels, route, network and candidate device. For a light-directed zone, separately engage a qualified light-system and WMS integrator; AIDC GO has not established a pick-to-light supply or integration offer here.
Send a redacted order profile, pick-zone map, exception rules, required handheld application/OS and receiving region through Contact. Ask which documented handheld configuration, accessories and support boundaries can be quoted. Keep the light-zone bidder’s installed bill of materials and WMS change scope alongside it so the two alternatives are genuinely comparable.
