Short answer: Consider pick-to-light for a defined zone with stable pick faces and a supported installation. Use Android PDA Barcode Scanners when instructions need to travel with workers across changing locations. Here RF means a network-connected warehouse handheld, not an RFID reader.
Compare the order profile and the whole installation
Use recent order lines, active locations, SKU movement and re-slotting frequency. A compact zone with repeated visits to stable faces can justify installed displays. A broad assortment or changing locations may suit instructions carried on a handheld. Neither conclusion follows from a demonstration aisle alone.
An RF quotation should include the exact handheld, scan and input arrangement, application, network access, charging and spares. A light-system quotation needs displays, controllers, installation, power or communications, location mapping, software connection and replacement modules. Compare complete systems and ongoing support.
Distinguish picking from putting
Pick-to-light indicates a stock location. Put-to-light indicates a destination container after goods are presented. Identify where the item is first recognized, where the order is selected and which acknowledgement closes the action.
A mixed installation can use lights in one zone and handhelds for reserve stock or exceptions. It needs one clear transaction rule when both interfaces touch the same order. Two confirmation paths must not post the same quantity independently.
Test the exceptions that affect a purchase
Give each proposed system a normal pick, a short pick, a re-slotted location and an unreadable label or unavailable display. Observe how the worker identifies the order, enters the actual quantity, finds an alternate location and sees the WMS result.
A light-button press can acknowledge a location without identifying the item. A handheld can identify an item while the wrong tote remains active. Define which location, item and container confirmations the task requires, then compare the stored result. Repeat-control testing helps when one action appears twice.
Include failure and change costs
Ask how work continues when a display, controller, handheld or wireless connection fails. Check spare-device sign-in and unresolved transaction handling. Demonstrate how a location change updates both physical identification and the system map.
Compare installation, retraining, support and expansion against the actual order profile. Send a redacted route map, application requirements, label samples and exception rules through Contact for a handheld quotation. Keep the light bidder’s installed equipment and WMS change scope beside it.
Device options for this task
Compare AIDC GO HX-21 and AIDC GO HX-27 for keypad-based barcode picking. Give the supplier the WMS client, label samples and required keys; obtain the light system and its software connection from the relevant system integrator.
