Through its arrangements with credit unions and mutual banks, Cuscal will make Samsung Pay available to 1.7 million Australian cardholders.
Cuscal joins Westpac, Citibank and American Express as partners of Samsung Pay in Australia.
Samsung Australia vice president Richard Fink said, "Every partner we bring onboard, whether it be a financial institution or retail brand through our Samsung Pay loyalty functionality, brings us a step closer to helping customers replace their wallets with their Samsung smartphone or smartwatch."
Samsung now has arrangements with more than 40 payments card brands in Australia and has 100 different types of loyalty cards loaded onto Samsung Pay.
Cuscal general manager of product and service Robert Bell said, "Our aim is to allow all of our clients to offer their customers the newest and best payment options available, to help them compete with much larger players."
