The Eftpos-friendly regulators at the Payments System Board have put in motion a process bound to give this payments scheme a leg up in negotiations with the industry over digital wallets and "dual-network debit cards".In a summary on matters considered at a meeting on Friday, the Payments System Board said this included "some issues impacting on competition and efficiency that have emerged relating to the use of dual-network debit cards in mobile wallets."The PSB said it "authorised the staff to prepare a paper addressing these issues for consultation with stakeholders."This paper is expected to be published in the coming weeks.At stake is an age old fuss over "choice", to the extent that Eftpos as a payments scheme has any age.Back in 2013 the RBA intervened in what was in essence the same dispute, except that on that occasion the internal industry wrangle involved, not wallet wizardry, but the modernisation of scheme debit card business practices to include the now standard chip.The PSB's language from its announcement in 2013 may provide a guide to its approach in the forthcoming consultation paper.It said then that, after negotiations between the three networks (Eftpos, Mastercard and Visa), "where an issuer [a bank] wishes to include applications from two networks on the same card and chip, the networks have agreed to work constructively with the issuer to allow this."The RBA said the networks had "also agreed not to prevent merchants exercising choice in the networks they accept, in both the contact and contactless environments.""In addition, the networks have agreed not to prevent merchants from exercising their own transaction routing priorities when there are two contactless debit applications on one card."
