In today’s warehouses, accuracy is everything. Yet a common problem quietly undermines efficiency: double barcodes. A pallet might carry both an old vendor label and a new warehouse license plate, or a carton may have a relocated barcode overlapping the original. The result? Confusion over which code to scan. Left unresolved, double barcode errors lead to mis-scans, delayed shipments, and costly inventory mistakes.
Traditional barcode readers offer safeguards, such as input validation to confirm that the scanned barcode follows the expected format. For instance, readers can often distinguish between a vendor’s label and a warehouse label. While this reduces some errors, it doesn’t solve the bigger challenge: multiple valid barcodes on the same pallet. Even when both codes “check out,” only one is correct for the WMS.
This is where Vimaan’s PalletSCAN suite — including PalletSCAN 360, PalletSCAN Overhead, and PalletSCAN 3D — takes warehouse accuracy to the next level. By layering computer vision and AI on top of standard validation, PalletSCAN ensures that the right barcode is captured every time.
Double barcode scenarios are surprisingly common:
● A pallet arrives with both supplier and warehouse labels.
● A carton has been relabeled, leaving the old barcode still visible.
● Multiple labels are stacked or placed on adjacent sides.
Even with input validation, workers are left to manually decide which code is correct. Handheld scanners slow down workflows as operators walk around a pallet, cover extra labels, and guess which one to capture. Fixed scanners may read whichever code appears first, even if it’s outdated. The result is frequent mis-scans, data entry errors, and rework.
Input Validation Helps, but Only Partially
Barcode readers can flag barcodes in the wrong format — for example, rejecting a vendor code when the system expects a warehouse license plate. But if both labels are in a valid format, the scanner cannot tell which one should be used.
Manual Decisions Remain Error-Prone
Workers must still choose which barcode to scan. Fatigue, time pressure, and human error all increase the chance of selecting the wrong one.
Extra Time Spent
Even cautious workers waste valuable minutes per pallet identifying and re-scanning labels.
Data Integrity at Risk
Once an incorrect barcode is scanned, the WMS records flawed data — showing the wrong location, quantity, or shipment info.
Warehouses need a solution that goes beyond validation: a way to intelligently distinguish between multiple valid barcodes and automatically select the right one.
PalletSCAN 360: Multi-Angle Forklift Accuracy
Mounted on forklifts, PalletSCAN 360 captures every visible pallet face as operators move through aisles. Instead of relying on workers to manually scan, the system uses AI to recognize label formats and context. If a pallet carries both a manufacturer’s barcode and a warehouse license plate, PalletSCAN 360 automatically identifies the correct one for the WMS. Operators keep working at full speed while errors are eliminated in real time.
For receiving and shipping areas, PalletSCAN Overhead units provide coverage where barcodes are most likely to cause delays. Cameras capture labels from the top and sides as pallets move under dock doors or choke points. The AI compares all barcodes, filters out outdated or irrelevant ones, and pushes only the correct data into the WMS. This removes the bottleneck of manual barcode checks during high-volume workflows.
The most comprehensive solution, PalletSCAN 3D captures all five visible sides of a pallet as it moves through a scanning tunnel. Multiple cameras record every label, and AI consolidates the data to identify the correct barcode — even when multiple valid barcodes are present. If conflicting data arises, PalletSCAN 3D applies WMS context or flags anomalies for review, ensuring no bad data slips through.
● Improved Inventory Accuracy – Clean, validated data every time.
● Faster Receiving & Shipping – Seconds instead of minutes per pallet.
● Reduced Labor Costs – No more wasted time covering, re-scanning, or double-checking.
● Higher Confidence & Traceability – Visual proof of every scan for audits and quality checks.
● Seamless Integration – PalletSCAN data flows directly into existing WMS systems.
While input validation reduces obvious barcode errors, it can’t fully solve the double barcode dilemma. That’s because both labels may pass validation but only one belongs in the WMS. Vimaan’s PalletSCAN suite bridges that gap by combining AI, vision, and automation to select the right barcode every time.
By eliminating double barcode mistakes, warehouses gain accuracy, speed, and operational confidence — without burdening workers with guesswork.
