A statement from the two companies said the Mastercard digital identity service would be progressively made available to all Optus six million customers who have downloaded the My Optus app.
"Optus' partnership with Mastercard provides our customers with the option to embrace the benefits of a digital identity, not only when they interact with us, but with other organisations too," said Vaughan Paul, Optus vice-president, Digital Consumer.
"ID solves pain points for our customers, such as protecting their identity, while at the same time simplifying the verification of their identity, giving them more control over their personal information and streamlining transactions."
"By using ID to verify a customer's identity for such requests, Optus joins a small group of proactive, multi-national organisations that are implementing biometrics to safeguard SIM registrations," the statement said.
"Mastercard and Optus are working closely to engineer a truly unique experience for customers that will better protect their personal identity information while enhancing their seamless onboarding and checkout experience," said Richard Wormald, division president, Mastercard Australasia.
"Bringing Optus, one of Australia's most trusted telco brands, into the ID ecosystem is an exciting step in Mastercard's digital journey. The partnership is a testament to the trust industry leaders and innovators are placing in Mastercard's global framework."
Ajay Bhalla, president, Cyber and Intelligence at Mastercard, said:."This collaboration builds on Mastercard's commitment to improve how people manage and use their digital identity, providing a more efficient way to interact with businesses and service providers in the physical and digital worlds.
"Collaborating with trusted technology providers, such as Optus, is critical for Mastercard as we advance the delivery of a globally scalable digital identity service."
