The project.

OpenPISP is an open direct bank-to-bank payment scheme for the UK market. The protocol is open. The reference implementation is open. The Scheme Authority is governed independently of the participants who build on the network.

The goal is not to displace card networks. It is to make them optional — to give merchants and payers a credible alternative when they want one, and to let that alternative grow on its own merits rather than through any single operator's market position.

This site is the Scheme Authority's public presence. The reference implementation lives in a separate repository and is published under an open licence.
