According to SamMobile, ‘highly credible sources’ inform the site Samsung’s next fingerprint sensor implementation on the upcoming Galaxy S6 will move to a touch-based sensor, just like Touch ID on the iPhone, instead of their current crappy swipe sensor:

Nonetheless, highly credible sources tell SamMobile that Samsung is ditching the swipe-based fingerprint sensor for a touch-based sensor for its next generation Galaxy S device. Furthermore, the sensor will work in the same manner as on the Huawei Ascend Mate 7 and the iPhone 5S / 6 / 6 Plus, sources confirm. Which means you will be able to enroll an entire fingerprint, unlike the swipe-based sensor, which only partially registered a fingerprint.

Honestly, what took Samsung so long to do this? The company must be falling behind!
