Samsung is allegedly heavily beefing up its Galaxy Note line
with features designed to blow the competition out of the water.
The Korean tech giant has recently filed a patent in South
Korea that pertains to a stylus that uses Ultrasound technology. According to
the patent application, the stylus will send out ultrasound waves, which will
be picked up by sensors on the side of the phone.

The use of ultrasound, should help future phone models to do
away with a screen digitizer which will allow for lower costs and a thinner
assembly. Apart from the improved stylus, future Note 4 models could also sport
a retina scanner.
The scanner will allegedly be used for unlocking the device
although it can also be used in making or receiving virtual payments much like
how PayPal has utilized the fingerprint reader on the Galaxy S5 for online
transactions.
