Samsung's wearables could employ fingerprint sensor
Considering that it is Synaptics and not Samsung making this revelation, it could be a matter of the supplier just "talking its position," especially when it doesn't seem so clear how such a feature could be of much use on a fitness band or smartwatch. Synaptics also believes that other companies besides Samsung, will start using biometrics on their wearable devices.
Apple is expected to expand its roster of Touch ID devices. According to connected KGI analyst Ming-Chi Kuo, all of Apple's new devices this year will feature the embedded fingerprint scanner, including this year's version of the both the 9.7 inch and 7.9 inch Apple iPads. There is no word on whether the Apple iWatch will offer such a feature.
