TouchID with Secure enclave plus iBeacon will be central to the whole iOS security system. TouchID secured NFC will be a secondary authentication method for backwards compatibility. iBeacon technology + TouchID authentication will be a much more seamless security system. It will be used for everything from payments to secured area access to alarm systems to ignition systems to a variety of authorizing systems in HomeKit and HealthKit. Time will tell.
