CBA app wants your location, biometrics in name of security — CIO Australia — “If we see a transaction coming out of Hong Kong but we know from a customer’s phone they’re in Melbourne or Sydney: straight away that gives us an opportunity to spot a discrepancy and block it straight away… If we’re not sure we’ll pop into the app with a question in real time and we ask the customer to help us, and they can swipe or click to say yep I’m comfortable with this or no this is something I don’t recognise.”
