Receipt Configurator for France
NF 525
France's Loi anti-fraude requires all POS systems to use certified software meeting NF 525 standards. Receipt Configurator's France compliance pack helps you meet these requirements through chaining, sequential numbering, and immutable audit trails.
NF 525 Requirements
Transaction Chaining
Every transaction must be cryptographically chained to the previous one with SHA-256 hashing — creating an immutable chain.
Sequential Numbering
Receipt numbers must be strictly sequential with no gaps. Validation runs on every render and flags any anomaly.
Data Immutability
Receipt data must be stored in an unalterable form. Any change requires a documented compensating transaction.
Certification Readiness
NF 525 certification requires audit logs and reproducible receipt rendering — both built in.
How Receipt Configurator Handles It
Chain hash injection
Each render includes the previous receipt hash and the new chain hash in fiscal metadata.
Sequential validators
Pre-publish checks ensure no gap or duplicate in numbering per terminal.
Audit-ready exports
Daily and on-demand exports of fiscal payloads in the NF 525 expected format.
Locked fiscal zones
Required fields are locked from designer modification.
