Westpac New Zealand customers will soon be able to log into their mobile banking app using fingerprint scanning.
In a world first, the bank has been taking advantage of the new Samsung Galaxy S5 handset's fingerprint sensor to carry out proof of concept testing.
If the system meets security standards, by the end of the year customers will be able to swipe their finger on their S5 to access their account.
WestPac says that it hopes to bring the feature to other handsets, notably the iPhone 5S. However, Apple has yet to open up its phone's fingerprint scanner to third parties.
PayPal is also using the Galaxy S5's biometric capabilities, letting customers login and shop at merchants on mobile and in-stores with their fingerprint.
Meanwhile, US Bank has been piloting voice biometrics technology which allows customers to access their accounts by speaking into their mobile phones.
