Westpac customers with an Apple iPhone, Samsung Galaxy S5 or Note 4 incorporating a fingerprint sensor will be able to use the technology to log into their mobile banking app from January 2015, the Australian bank has announced. “This is the next step in moving forward our already successful digital banking service Westpac Live which has been used by over 2.9m customers to manage their accounts on the move,” says the bank’s Jason Yetton.
