Seamless item-level visibility in one place

Visibility Console

True visibility is to know about the condition of what’s inside the box, not the container or truck itself.

Better visibility to ensure product quality

We provide detailed condition visibility for better quality control in transit by seamlessly integrating our solution with existing enterprise softwares or product database. Our customers can now avoid accountability issues with verifiable audit trail and no longer go through manual product-device mapping work.

Immediate response anywhere anytime

Our visibility console provides visibility into where shipments are at any given moment as well as potential risks associated with them. With user friendly dashboard and customizable alert management feature help our customers minimize any disruption caused by temperature excursion or other unforeseen issues that may arise during transit.

Real-time cargo monitoring dashboard

Workflow management

We also support return management when exceptions occurred and help customers have full control over supply chain on any occasion by automating return and manual process. The item-level data integration allows companies to immediately proceed with the process without cumbersome field operations.

Minimizing human error with digital document management

Without filling out a separate receipt or certificate, electronic shipping certificates are automatically issued based on the temperature history, shipment, and arrival information. Able to store records digitally without the risk of data loss or damage that may occur when storing paper documents.
