The fingerprint sensor made by Authentec, was the centerpiece of a Motorola Moto X1 and slated to be in Google's Nexus 6 before Apple bought their supplier, effectively preventing the release. That's why those devices were released with a dimple where the fingerprint sensor was going to be, even though there was nothing in that spot where the finger rests.

That is to say, TouchID capacitive fingerprint scanning was going to be shipped in Android first and Apple delayed the market introduction with a strategic acquisition.

Prior devices like the Motorola Atrix and Toshiba G500 also had fingerprint biometrics.
