Swiss QR Validator

The Swiss QR Validator analyzes the payload encoded in a Swiss QR-bill to verify data integrity and readiness for posting. It accepts the raw payload text extracted from the QR code and returns a machine-readable summary of field values, plus a list of detected issues. This supports finance teams, auditors, and developers by validating payload structure, mandatory data, and reference correctness before processing payments. Conceptually, it parses the payload into creditor data, IBAN, amount, currency, and reference, then applies deterministic checks such as IBAN validity, mandatory presence of beneficiary data, reference type consistency, and optional currency checks when an amount is present. It provides a clear, extractable results schema that downstream systems can consume. Unique value comes from precise field extraction combined with explicit error reporting and guidance for fixes, enabling pre-validation in accounting workflows and automated data-entry pipelines. Core features include input validation, field extraction, presence and format checks, reference-type recognition (QRR/SCOR), currency checks for CHF, and an exportable results schema. It also reports edge cases such as missing mandatory lines, invalid IBAN checksums, unsupported reference types, and inconsistent currency-amount pairs. The tool supports Swiss locale standards and adheres to ISO references where applicable, while remaining agnostic to external banking systems and live data.
