The GS5's Home button is actually a miniature Synaptics Natural ID capacitive sensing device. Using software embedded in the fingerprint settings panel, the device scans the subcutaneous skin patterns of as many as three fingers (or thumbs) from multiple angles and stores them for later comparison. Actual fingerprints are not stored, nor do scans ever leave the device. For the enterprise, Samsung's device can be used for more than simply securing device access, as is one limitation of the scanner in Apple's iPhone 5s. The GS5's scanner can be tied to in-app authentication, such as for commerce apps and to secure certain portions of the device's storage.
