Spanish Fiscalization: Mandatory Hashing for Billing, Registration, Cancellation, and Event Log Records

• Spanish fiscalization rules require certain digital documents to include a unique “hash” or digital footprint.
• The hash requirement applies to all records from Computer Billing Systems (SIF), including billing, registration, and cancellation records.
• Non-verifiable systems that generate event logs must also include a hash for those logs.
• The hash serves as a digital seal to detect any tampering or manipulation of records.
