New data from Commonwealth Bank in Australia reveals customers are increasingly reaching for their smartphones instead of their wallets at the checkout, with user growth up 35 percent in the past six months, according to a press release.

With five million CommBank app users, tap and pay transactions have numbered 16.8 million for the six months to June 2018.

Today's announcement comes as Visa cardholders can now make contactless payments via CBA's Tap & Pay functionality in the CommBank app. Samsung Pay and Google Pay are also now available for Visa cardholders as well as payments via Fitbit and Garmin's payment-enabled smartwatches.

Michael Baumann, CBA's acting Executive General Manager, Everyday Banking, said that by enabling Visa across the suite of CBA supported digital wallets the bank is combining choice and convenience for more customers.

"Since 2013, our customers have been able to use their smartphones to make payments," he said. "By extending the suite of CBA supported digital wallets to our Visa cardholders, we're providing our customers with even more options to make a payment at the point of sale, whether that be through the CommBank app or their smartwatch."
