It seems unlikely that any sensible system would use fingerprint data for security, given how easy it is to spoof. You leave your fingerprints everywhere and can't protect them once you've left the area. Authenticator + smart phone is not ideal but it's still better than fingerprints. It's harder to steal a phone from somebody, while it's almost impossible to prevent the theft of your fingerprints.
