A statement from Mastercard said the service had been extended this month to verify credentials for students who were taking exams online.
Secure connections and integration with services from other providers like Australia Post were tested in the latest trial.
"The rising demand for, and myriad challenges of, premium online education is accelerating the implementation of new solutions for the global higher education sector," said William Confalonieri, chief digital officer at Deakin University.
During the pilot. students created digital identities in Australia Post's Digital ID app and used them to access Deakin's exam portal. Having been successfully integrated into both platforms, ID was able to orchestrate the sharing of verified identity data.
"As the number of online transactions grows, so does the need for individuals and organisations to have access to a safe, convenient and uniform way to verify a person's identity in both the physical and digital worlds," said Australia Post Identity Products and Services general manager Christian Seely.
"By collaborating with other industry leaders such as Mastercard, we can help grow adoption of digital identity in Australia, tackle fraud and improve trust in online interactions."
Mastercard Australasia division president Richard Wormald said: "Digital identity must be built on a framework of trust, partnership and consumer choice.
"Demonstrating this level of inter-operability points to the huge potential for more partners across more sectors – such as telecoms, retail, banking and government – to provide greater value and impact.
"Integrating with ID's highly secure network enables these services to extend the reach of their existing offering, while enabling consumers to stay in complete control over where their identity data is stored and how it is used."
