Check in objects

and digitally understand

markUID's check-in system enables seamless, tamper-proof documentation of all interactions and states of an object - from the start of production to the last use.

With markUID's check-in functionality, every physical object becomes a carrier of dynamic, context-related information. In addition to the static identity from the UID master record, a simple API call allows relevant event data to be added: Who acted when and where? What were the environmental conditions? Which measured values were recorded? This information - supplemented by user-defined metadata - is cryptographically linked to the UID. An integrated ledger system also automatically logs passive interactions such as scans. All data is accessible via the web application or via API - in real time, audit-proof and fully traceable. This creates a digital image of your property's life cycle - for maximum transparency, efficiency and trust.

Smart Traceability

in every scale

With markUID, you can capture all relevant product data in a structured and automated way. This allows you to analyze trends and optimization opportunities across your entire company, from individual UIDs to entire batches and product lines.

Every physical object contains information - markUID makes it visible and usable. Standardized, structured data collection along the entire supply chain creates a consistent data pool that goes far beyond simple traceability. Individual check-ins become building blocks of a larger picture: they identify trends in quality, correlations between location and defect frequency or systematic weaknesses in production lines. Thanks to the standardized format, these findings are also accessible to small companies for the first time - without expensive IT projects. The easy-to-integrate API, flexible metadata fields and scalable platform enable a step-by-step introduction - from pilot projects to the global linking of all products. With markUID, every object biography becomes a source of business insight - big data, without the complexity.
