fiskaltrust's Solutions for France
NF525: Certified POS Systems
The NF525 standard ensures that all cash register software and POS systems used in France comply with anti-fraud regulations.
Key Requirements of the French Fiscal Law:
- Certification or Self-Attestation: POS software must either be certified by an approved body (e.g. LNE, Afnor) or self-attested by the publisher to meet legal criteria.
- Tamper-Proof Journal: All transaction data must be stored in an immutable and traceable format.
- Digital Signatures: Each receipt must be cryptographically signed to prevent alteration.
- Audit Export: The system must be able to generate a legally compliant export (FEC or similar) upon request.
Key Benefits for Developers
- LNE-Certified Middleware: fiskaltrust.Middleware is officially certified in France, removing the need for additional certification efforts.
- Stable, Open-Source API: One integration point for all fiscal workflows across Europe.
- No Vendor Lock-In: Use any supported hardware or cloud setup without dependency on specific suppliers.
- Automatic Legal Updates: fiskaltrust ensures that your integration remains compliant as laws evolve.
Integration with the fiskaltrust Middleware API
Developers integrate with a single API to handle:
- Receipt signing via an SCU (Signature Creation Unit) tied to the business’s SIRET.
- Secure journaling and data hashing to meet French anti-fraud standards.
- Receipt generation in compliant formats (including HTML, PDF, QR code, and printable ESC/POS output).
- Self-service onboarding, monitoring, and device configuration through the fiskaltrust.Portal.
Compliance Automation
Once connected:
- fiskaltrust.Middleware validates and signs each transaction based on French legal requirements.
- The SCU ensures receipts are tamper-proof and traceable.
- A legally auditable transaction journal is maintained.
- Predefined ReceiptCases help developers structure data based on transaction types (e.g. invoice, refund, deposit).
Continuous EU-Wide Compliance
fiskaltrust monitors French tax regulation changes and updates the system automatically.
- Developers don’t need to update their own POS logic or fiscal modules.
- Middleware enhancements are deployed centrally, minimising downtime or rollout effort.
Stable API. Open source. Audit-proof receipts. No vendor lock-in.
