Banks may be in a position to better promote the Eftpos scheme along with scheme credit and debit cards, after the Reserve Bank of Australia brokered an agreement between the parties.The RBA's Payments System Board said yesterday that the three networks (Eftpos, Mastercard and Visa) had agreed that "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."Interpretations of what was agreed may vary.Eftpos' managing director, Bruce Mansfield, said in a media release that "the announcement ensures that new or replacement multi-network debit cards can carry the Eftpos function and logo."Whether what the industry is calling dual cards will have to carry the Eftpos logo prominently is in dispute, however.Visa's country manager, Vipin Kalra, said in a statement that "the agreement endorses Visa's long-standing position that we do allow the issuance of dual network debit cards.""We're pleased that it preserves Visa's right to be the exclusive logo on the front of Visa cards, and for Visa payWave to be the primary contactless payment application on all Visa payWave cards."This interpretation allows for the Eftpos logo to be relegated to the back of the card, as it sometimes is today.For Eftpos, the wider opportunity is to make sure that its scheme catches up with the burgeoning use of contactless payments.The wider business issue for banks is the need to cater to choice by merchants on which system they use to process a debit card payment.One solution is to simply route payments over the network that attracts the lowest merchant fee.
