FlexiGroup chief executive Symon Brewis-Weston said the launch of Apple Pay demonstrated the company's commitment to being a leader in providing consumer finance and an alternative to major banks.
"There is no doubt that Apple Pay leads the way in mobile payment technology and the launch is part of the focus on delivering innovative and tailored financial solutions to our customers," he said.
"We are committed to enhancing our offering to cardholders by providing increased ease and convenience in how they pay for goods and services."
CBS made a second bid for an Apple Pay deal on its own on Friday.
FlexiGroup's announcement means that it joins ANZ and a few other institutions in making Apple Pay available to its customers.
