Apple, as I'm sure you know, revealed two new iPhone models on Tuesday - the cheaper iPhone 5C and the latest of update of its flagship mobile device, the iPhone 5S.
The most talked about feature of the 5S is the new fingerprint sensor Touch ID, which allows users to replace their passwords by using their fingerprints. Naturally, the privacy and security implications of this have been a constant topic of discussion in the media since the announcement, but Apple has put out a video discussing the feature in hopes that people will get a better idea of how it works.
