Physical Handover Evidence
Evidence is created at the moment responsibility changes between people, machines or autonomous systems.
Multiple equivalent perspectives
Each participating device creates its own, secure perspective of the physical interaction.
Unified Digital Evidence
The object, visible condition, participants and transaction context are linked in a verifiable record.
The Principle behind Visual Handshake
Conventional documentation often starts after a physical handover has already taken place. The resulting image may show an object, but it does not reliably connect the documentation to the actual interaction or the participating parties. Visual Handshake creates the evidence directly during the handover. The participating devices capture independent perspectives of the interaction and cryptographically link them to the object, visible condition and transaction context. The Trust Layer protects the integrity of each digital record. Visual Handshake connects those records to the physical event, creating a verifiable Chain of Custody.
Built for Verifiable Physical Handovers
The Trust Layer extension connects independently captured perspectives to the same physical handover, creating evidence of the physical interaction that remains verifiable across devices and systems.
Event-Bound Evidence
The evidence is created as part of the handover process and linked to the corresponding transaction.
Cryptographically Linked Perspectives
The independently secured records of the participating devices are linked to the same physical interaction.
Cross-Device Integration
Visual Handshake can run on smartphones, logistics handhelds, industrial cameras and robotic systems, supporting human-to-human, human-to-machine and machine-to-machine handovers.
How It Works
Two participating devices create independently verifiable evidence of the same physical handover: Verifiable evidence of who or which system handed over what, to whom, when, where and in what visible condition.
01
Capture
Each device captures the object, its visible condition and a live signal from the participating counterparty or system.
02
Bind
The evidence is signed and cryptographically linked to the participating devices, transaction context, time and location.
03
Verify
After the handover, authorized systems can independently verify the integrity, provenance and relationship between the secured records.
