When Apple announced the iPhone 5s, one of the key features of the handset was its Touch ID fingerprint sensor. As the sensor could be used to unlock the phone and make purchases on the iTunes App Store, it is understandable that Apple did not want developers accessing the Touch ID sensor. In fact Apple got a lot of flack over the security of Touch. However it seems that despite all those concerns, Samsung has decided to open up its fingerprint scanner on the Galaxy S5 to developers.
