Mobile Devices will also host apps from Issuers which will enable the Issuer to push authentication to the mobile device. The Issuer App will work natively and support very strong device identification, in ways which are not possible with browsers.
Mobile devices are also ideal for biometrics including fingerprint, face recognition and voice recognition (remember Alexia). With the native support on mobile devices, biometrics will become a mainstream method of authentication.
Issuer Banking Apps will also provide out of band authentication for other payment channels such as browser based payments. Rather than send an SMS, the Issuer Banking App will automatically pop up on the device and a simple press of the OK button or use of biometrics will be sufficient to authenticate.
