Apple’s iPhone 5S comes with a built in fingerprint scanner that Apple calls Touch ID, Touch ID is used to unlock your iPhone when you place your finger on the sensor.
There have been concerns that this could possibly be hacked, although the data on your fingerprint is actually stored on the device and not on Apple’s servers.

Now it would appear that Apple has added an extra layer of security into its Touch ID, and hasn’t told anyone about it. Each fingerptint sensor is tied to one device.
This was discovered by repair company mendmyi and the guys from iMore, and what this means is that each individual Touch ID is tied to an individual handset, a Touch ID from one iPhone will not work in another.
Apple’s Touch ID communicates with the iPhone 5S A7 processor when you unlock your device, and it is thought that the individual Touch ID has been made to work only with one iPhone to stop any sort of interception between the sensor and the A7 processor.
So it looks like Apple’s Touch ID has an extra layer of security protection on top of what Apple has already announced, you can find out more details over at iMore.
