Support for refunding is a part of the "standardized" authorization process. However, the Saturn scheme is probably not particularly interesting from a W3C perspective since it *cannot be implemented using existing Web technologies*. OTOH, Saturn appears to be in "good company" together with Android Pay, Apple Pay, and their hundreds of lesser known "cousins". The [anticipated] next project phase is getting support for security hardware since it doesn't seem worthwhile introducing anything that already on the "drawing board" is worse than *shipping* state-of-the-art products like Apple Pay. This project is fortunately "neutral" [*] and not in any way tied to Saturn. If successful, it could become a replacement for the currently dormant Hardware Based Security Services CG. Anders *] In fact, all the underpinning technologies used in Saturn were designed to be neutral, with the aim enabling the market creating competing schemes as well.

I say “organized” because the merchant is not supposed to get the IBAN of the payer but its bank knows it. So the merchant could ask its bank to send a credit transfer to the payer. > > - For the SEPAmail system, the refund is organised using the JADE application in the backoffice of the merchant using the same identifier used in the payment transaction (QXBAN) > > - For the SEPA direct debit, it is even simpler because the merchant knows the IBAN of the payer so he could sent a credit transfer > > - Other systems, I don’t know > > > > I think that a merchant gets enough information during the payment phase to organize later a refund.
