There are at least two ways to hack the TouchID finger print sensor in iPhone 5S. One is very easy for your girlfriend or boyfriend to do while the other one involves more effort.
Before we continue, please remember that I DO NOT advocate hacking someone else’s iPhone 5S. You shouldn’t have something in your iPhone that your girl would want to hack your iPhone 5S to find out. But you would be aware that your iPhone 5S isn’t hack proof.

‘Sleep-hack’ iPhone 5S’ TouchID Sensor
Thsi is the easy method. When the owner of that iPhone 5S is already asleep, use his finger to gain access to his or her iPhone 5S.
“The [RF capacitive sensor] technology is built in a way that the [fingerprint] image has to be taken from a live finger,” Sebastien Taveau told Mashable. That means you can’t use a cut or dead finger to unlock an iPhone 5S using the TouchID finger print sensor.
Copy Someone Else’s Finger Print and Unlock His or Her iPhone 5S
You just have to acquire the owner’s finger print from a glass or his own iPhone 5S. Next, Retrieve that print using standard forensic methods and take a photo of it at 2400 dots per inch (dpi). Then, you’ll have to invert the image and print it in a transparency film. After the that, the print is covered with wood glue and set to dry. Finally, cut the dry wood glue to cover your finger and use it to unlock the iPhone 5S.
That’s it! Here’s the video from CCC showing how they did the procedure above.
