The fourth quarter of 2017 is now the slated time for Australia's New Payments Platform to lurch into action.Paul Lahiff, chair of NPP Australia, rattled through a few topics yesterday with Banking Day."We're still running to schedule," he said, parrying a query over the sector's tendency for holdups when some collaborator or other drags the chain."The central build, which SWIFT is working on, is running to schedule."The 13 participants are running to timetable and we're still keen to open the doors to other players."Lahiff said the number of organisations connected would "more likely … be in the 80s or 90s by the time we go live" with many niche ADIs networked through payment gateways such as Cuscal, Indue and ASL."You've got to be able to settle with the RBA," Lahiff said, a choke on new entrants supervised by APRA."You need an exchange settlement account with the RBA and you need an APRA ADI licence."Allowing for the ADI collar the NPP platform has an open structure, described as "layered.""I think we'll see a pretty vibrant secondary market develop over time," Lahiff said.The overlay rollout is as before. Bpay, owned by the big banks is working on the first overlay."This will be the initial convenience service," Lahiff said."This will be a speedy payment, cleared and paid in a matter of seconds."There will be no need for a BSB, with modern addressing options central to the build, Lahiff said."An email is ok, a mobile number ok, an alias, an ABN."Banks and the NPP are counting on a long used messaging standard to play catch up, ISO 20022 guidelines rendering bank data in the latest design.Payments are getting a genuinely new platform in Australia, a build out in a way of SWIFT's global network, with a ton of decay resistant local plumbing.ISO 20022 "allows a lot of information to go with each payment message," Lahiff said, and will be a radical reform when it arrives."We'll see more overlays developed over 2017, 2018 and 2019," he said."I expect to see a fertile environment," Lahiff said, pointing to the many bank skunkworks.
