Digital trust services for the automotive industry
Qualified electronic signatures, electronic seals and record signatures for contracts, certificates, test reports, digital product passports and large-scale automotive processes.
SIGN8 helps OEMs, suppliers, battery manufacturers, dealer groups, leasing companies and testing organisations to secure digital documents and data in a legally binding, tamper-proof and scalable manner.











The challenges facing the industry
Digitalisation in the automotive sector
Building trust where it has been lacking
Digital contracts, certificates and product data require new solutions for traceability, integrity and scalability.
Whether in vehicle sales, leasing, MOT reports, the Digital Product Passport or throughout the supply chain: companies need a reliable trust infrastructure that enables documents and data to be digitally secured, validated and processed automatically.
Documents & attestations
Media breaks in purchase and leasing contracts
Risks of tampering with digital documents
- Lack of traceability in product and supply chains
Systems & Scalability
Different systems used by OEMs, dealers, suppliers and testing centres
The need for API-enabled, scalable signature and seal processes
Processes & manual effort
A high level of manual work involved in producing test reports
Large volumes of documents and records
Popular use cases for trust services in the automotive industry
Digital Certificate of Conformity (eCoC)
Structured vehicle data must be electronically signed for registration purposes and made available to the registration authorities in digital form.

Who is this relevant for?
- Vehicle manufacturer
- Suppliers of type-approval and automotive systems
- Vehicle registration offices

What is the challenge?
Vehicle data must be reliable for registration and inspections – yet digital records are susceptible to tampering. A solution is therefore needed that provides unequivocal proof of the data’s origin, integrity and association with a specific vehicle.

What does the use case look like?
Following production, the manufacturer issues an electronic Certificate of Conformity (eCoC) for each vehicle. The structured data record is digitally sealed and transmitted to the regulatory infrastructure. The authorities can then retrieve the vehicle data in a tamper-proof manner and use it for their processes.

Our solution
SIGN8 provides the necessary digital seal certificates and the technical trust infrastructure. Vehicle manufacturers can automatically apply digital seals to eCoC data records, thereby verifiably ensuring the provenance and integrity of the transmitted vehicle data.

Digital Product Passport (DPP)
Every battery, every component and every single attribute in the Digital Product Passport must be more than just an entry in a database. It must be verifiably accurate – in such a way that it stands up to scrutiny by regulatory authorities, customers and the courts.

Who is this relevant for?
- OEMs
- Battery manufacturer
- Suppliers
- DPP platform providers
- Recycling companies

What is the challenge?
In future, batteries, components and individual product attributes must be documented in a way that is digitally traceable, verifiable and trustworthy. It is not enough simply to store data. What is crucial is who created, validated or amended this data.

What does the use case look like?
In the Digital Product Passport, each component is assigned a tamper-proof digital identity – complete with all relevant documentation regarding its origin, properties and life cycle. Trust services safeguard this data: through qualified signatures and seals, they guarantee that the information is forgery-proof and cannot be altered.

Our solution
SIGN8 assists with registration on the DPP Platform. We can also digitally sign or electronically seal individual attributes or entire data sets to ensure that product data is verifiable and tamper-proof.
TÜV documents, test reports and certificates
Technical documents must be verifiably accurate at all times. Electronic signatures and seals help to prove the authenticity and integrity of these documents beyond any doubt.

Who is this relevant for?
- TÜV organisations
- Technical services
- Workshops
- Insurance
- Fleet operators
- Car dealer

What is the challenge?
Test reports, expert opinions and technical certificates are often shared digitally. Recipients must be able to verify that a document is genuine, complete and unaltered.

What does the use case look like?
Technical documents are created digitally and bear an electronic seal to prove their authenticity and legal validity.

Our solution
SIGN8 is authorised to provide legally valid electronic seals in accordance with eIDAS, which can be applied to documents. This can be done both remotely and locally.

Leasing and contracts of sale
Leasing and purchase contracts for vehicles can be legally concluded digitally using a qualified electronic signature – whether at a local car dealership or when ordering online.

Who is this relevant for?
- Car dealer
- Leasing companies
- Online vehicle platforms
- Captive banks

What is the challenge?
Purchasing and leasing processes are often time-sensitive and involve a lot of paperwork and involve several parties. Media breaks lead to delays and a poor customer experience.

What does the use case look like?
All parties involved in a vehicle purchase (e.g. the customer, the dealer and the financial services provider) can sign the necessary documents digitally, in a legally valid manner and without any disruption to the process.

Our solution
Our Signing API enables qualified electronic signatures to be integrated directly into dealer management or leasing platforms, ensuring legally compliant, paperless processes without any disruption to workflows.
Supply Chain, ESG and Attribute Certification
Compliance documentation is created digitally and stamped with an electronic seal. This ensures that the origin and integrity of the document can be verified beyond doubt at a later date.

Who is this relevant for?
- OEMs
- Suppliers
- Battery producer
- Purchasing departments
- Quality management
- Sustainability teams
- Auditors

What is the challenge?
Automotive supply chains are highly complex, and every component must be traceable. Whether it is quality certificates, origin data, carbon footprints or ESG information: all details must be reliable, auditable and traceable throughout the entire product life cycle. Without digital solutions, this is virtually impossible.

What does the use case look like?
Every stage of the value chain – from material procurement through production to recycling – can be verifiably documented using digital signatures. This creates a tamper-proof and auditable data foundation for compliance and ESG reporting requirements.

Our solution
SIGN8 enables the electronic sealing of supplier declarations, certificates and structured attributes. This allows evidence to be digitally secured throughout the supply chain.
