Use cases · Public aid and subsidies
Tens of thousands of aid applications, self-declared documents to verify, and fraud discovered after payment?
Paying public aid at scale, without fraud and with the proof.
Trustia already operates the mass processing of electric-mobility aid funded by a State scheme: the electric-vehicle purchase premiums that come from energy savings certificates. The same building blocks apply to any aid or subsidy scheme: eligibility verified against official sources, document fraud blocked before payment, payment to a verified account, a full audit trail for inspection.

In plain words
The words of the scheme.
- CEE
- Energy savings certificates: a State scheme that has energy sellers fund energy savings. Among other things, it funds a premium for buying electric vehicles.
- KYC
- Know Your Customer: verifying a person’s identity, with their ID document, a liveness check and the asset-freeze lists.
- KYB
- Know Your Business: verifying that a company exists, is active and is up to date with its obligations.
The problem.
What we put in place
The journey, step by step.
An applicant journey that matches the scheme.
On mobile, one document at a time, with automatic reminders. The applicant always knows what is missing.
The tax notice verified with the tax authority.
Tax number, notice reference and 2D-Doc code: the reference tax income and the number of tax shares come from the source, not from the document. An altered notice does not get through.
Identity verified (KYC).
Document read and MRZ strip checked, liveness check through a certified provider, France Identité proof, asset-freeze lists.
Cross-checks with public databases and external data.
Sirene, Base Adresse Nationale, land register, vehicle registrations, professional qualifications, and comparison of the documents with each other: an inconsistency blocks the file.
Payment to a verified account.
The holder’s name is confirmed by their bank, the account details matched with the identity, the transfers go out in batches.

A real case
Electric-vehicle purchase aid, at national scale.
On electric-vehicle purchase aid schemes, Trustia processes about 300,000 files a year on behalf of carmakers, distribution networks and funders.
Each file goes through verification of the tax notice at the source, a check of the ID document, cross-checks of the documents with each other and verification of the bank account before payment.
Result: €1bn in secured financial flows and 10 million documents processed per year, with fraud blocked before payment.

Your questions
What we are asked most.
Can you respond to a call for tenders?
Yes. Our references cover national aid schemes at scale; we provide a technical proposal, security guarantees and a reversibility plan.
Where is the data hosted?
In France, with a European hosting provider, with backups and regular restore tests.
Can you absorb a peak of several tens of thousands of applications?
Yes: processing is automatic, only doubtful cases go to an officer.
What do you do with detected fraud?
The file is blocked before payment, the proof is attached, and reporting follows the rules you set.
Do you verify identities yourselves?
The document, the lists and the consistency of the file, yes; face matching and the liveness check are run by a certified provider, built into the journey.
