https://github.com/largo/swiss_qr

Parses the payload of the Swiss QR Code on a Swiss QR-bill (QR-Rechnung, QR-facture, QR-fattura; Switzerland and Liechtenstein) per the SIX Swiss Implementation Guidelines for the QR-bill ("SPC"/"0200") into immutable value objects: account and QR-IBAN, creditor and debtor addresses, amount, currency, QR/creditor reference, message, Swico S1 billing information and alternative procedures. Validates every rule of the guidelines, including IBAN, QR reference and ISO 11649 check digits. Optionally reads the QR codes from images and PDFs with the qr_reader gem.
