Warehouse Wearable Ring Scanner for Order Picking – Case Study of a Leading Korean Logistics Company
A leading logistics company in South Korea was looking for a wearable ring scanner to improve productivity in its warehouse order picking and parcel sorting operations. Warehouse operators needed to scan shipping labels continuously while handling cartons and packages. Because both hands were frequently occupied, the customer required a hands-free barcode scanning solution that could improve workflow efficiency without restricting worker movement.
However, many shipping labels were poorly printed, damaged during transportation, or had low contrast, resulting in inconsistent scanning performance and frequent rescanning. The customer also required a rugged scanner capable of withstanding the demanding conditions of daily warehouse operations.
Challenge
The customer was looking for a wearable barcode scanner that could:
• Improve first-pass reading of damaged or low-quality shipping labels
• Reduce rescanning during warehouse order picking
• Support hands-free barcode scanning to improve worker productivity
• Pair wirelessly with warehouse mobile computers via Bluetooth
• Withstand dust, splashes, and everyday warehouse environments
• Maintain stable performance throughout long working shifts
Solution
Based on the customer's warehouse workflow, NUMA customized the NRS-68 Bluetooth Wearable Ring Scanner to improve barcode reading performance for damaged and low-quality shipping labels. The NRS-68 combines Bluetooth wireless communication with a lightweight wearable ring design, allowing operators to keep both hands free while scanning. Firmware optimization further enhanced decoding performance for challenging logistics labels, reducing the need for repeated scans. Designed for demanding warehouse environments, the NRS-68 features an IP54-rated housing for protection against dust and water splashes, while Bluetooth connectivity ensures reliable communication with warehouse mobile computers throughout the workday.
Result
After deploying the customized NRS-68 solution, the logistics company achieved several operational improvements:
• Improved first-pass reading of damaged and low-quality shipping labels
• Reduced rescanning during warehouse order picking and parcel sorting
• Increased worker productivity through hands-free barcode scanning
• Simplified daily warehouse workflows
• Maintained reliable Bluetooth communication throughout warehouse operations
• Delivered stable scanning performance during long working shifts
