One of the more intriguing features announced with the iPhone 5s is its fingerprint scanner, raising questions around security and how it would actually be used.
The fingerprint scanner uses biometrics - taking your fingerprint (which is unique to you, obviously) and using it as a foolproof password. Or is it?
Will burglars be wanting more than just an iPhone, and go after your extremeties as well?
According to Mashable, the iPhone 5S's fingerprint sensor detects the sub-epidermal layers of your skin, meaning it won't work unless the finger used is also attached to a living human being.
"The [RF capacitive sensor] technology is built in a way that the [fingerprint] image has to be taken from a live finger," Sebastien Taveau, an expert on fingerprint technology told Mashable.
Meanwhile other sources have thrown doubt on the claim, saying that any such assertions are mere speculation until the phone has been released and experts can properly assess what technolgy lies beneath the hood.
