About
About this explorer
A payment crosses a border halfway through its life: JSON over HTTPS on the TPP side, ISO 20022 XML on the bank side. This site holds both vocabularies in one catalog.
OpenFinance is published by GeoKing. It is an educational catalog of European payment schemes, infrastructures and ISO 20022 messages. It is not a bank, a payment service, or financial, legal or investment advice.

Mastercard entries describe Open Finance US product vocabulary (Data Connect, FinBanks, Partner Linked). They sit beside EU/UK PSD2 terms so the same catalog covers both dialects — they are not interchangeable legal definitions.
