Auto-capture palletized product data with Neuralstack, a novel, powerful Al-based vision platform. Neuralstack leverages exceptional 2D image quality and 3D data through the newest generation of Apple iPhones. Case counting, barcode reading in batches, OCR text extraction and classification, and critical pallet and case features are digitized, cross-referenced and transferred with lightening speed into your inventory tracking system. No Manual Data Entry: Neuralstack auto-populates your critical inventory data points into your ERP I WMS | WES platform. Implementing two-way data flow with your inventory system allows for exceptions handling through data matching. Accurate Counting: Neuralstack counts palletized product inventory by SKU in inbound and outbound processes, critical for accounting accuracy and avoiding shrinkage. Barcode Bulk Scanning: Neuralstack auto-scans 1D and 2D barcodes in batches from your pallet. That barcode data is then combined and cross-referenced with other inferred data to maximize data collection and tracking accuracy. Detect and Store: The advent of Al-based vision systems allows for better, faster detection of damaged items or important physical features. Neuralstack makes it effortless to flag issues and retain audit trails.
