A new app for Android smartphones turns the lock screen into a finger scanner, a feature incorporated by Apple in its latest iPhone 5S. The ICE Unlock Fingerprint Secure adds camera-powered fingerprint scanning to Android’s lock screen and instead of real-time sensors; it relies on matching images of the finger to unlock the phone. The free app initially ‘enrolls’ a person’s fingerprint by taking two photos of a finger and every time one needs to unlock the phone, they need to place the finger exactly the same way within an on-screen oval, and wait for the app to match it with the ‘enrolled’ fingerprint.
