The Commonwealth Bank of Australia (CBA) has announced a trial of a redesigned banking app that it says has been backed by "world-leading" machine learning, data analytics, and behavioural science. The bank said its app boasts 5.3 million unique users and more than 6.5 million log-ons per day. It expects the redesign will provide the "first completely personalised and smart digital banking experience in Australia, backed by world-leading application of machine learning technology". According to chief digital officer Pete Steel, CBA has a "unique ability to use technology and innovation capabilities to support good financial habits". "We're using a combination of cutting edge machine learning technology, data analytics, and behavioural science to develop smart banking features to create a highly personalised digital banking experience," he said.
