Dutch bank ING Netherlands has become the first European bank to deploy voice biometrics on its mobile banking app.After installing an update available from today, customers can authorise transactions by conversing with a virtual assistant on their phone.Previously the assistant, called “Inge”, could only carry out basic tasks such as check their bank balance.However, it has now been integrated with additional voice biometric security developed by Nuance – Inge is the Dutch equivalent of the company's “Nina”, a virtual assistant with whom customers can engage in conversational speech.The bank says that feedback from early users has helped refine the application to the extent that it now feels confident to extend deployment to payments initiation, describing it as smart, intuitive alternative to PINs and passwords.Jeroen Losekoot, Internet & mobile marketing manager at ING, says: “Thanks in part to the inclusion of biometric applications, we are able to make banking faster, smoother and easier for our customers and improve access.”Last November, ING became one of the first European banks to install fingerprint authentication on its app, deploying it in Belgium and using Apple's TouchID.
