Former Apple employee and human interface developer Bruze Tognazzini posted a recent blogthat covers what he thinks the watch would have in the way of functionality.
' The watch can and should, for most of us, eliminate passcodes altogether on iPhones, and Macs and, if Apple's smart, PCs: As long as my watch is in range, let me in! That, to me, would be the single-most compelling feature a smartwatch could offer: If the watch did nothing but release me from having to enter my passcode/password 10 to 20 times a day, I would buy it.
As with passcodes, the watch could be used in conjunction with Find My iPhone, sounding an alert when a user moves out of range of the device.
The NFC chip belongs in the iWatch, not in the iPhone! That way we'll know exactly where it is at all times, strapped to the end of an appendage expressly designed to be waved around at things. How handy! Reach. Touch. Done.
Meanwhile, our iPhone, handling any necessary communication, will stay hidden safely away, and, if someone does manage to get ahold of our watch, it will require reauthorization, having been removed from our arm. Net value to the thief: Zilch. Net loss to us: A whole lot less than an iPhone, with word on the street quickly making it clear there's no point in stealing an iWatch.
Of course, not every merchant will accept NFC right away, so the watch, linked to Passport, will also display QR codes, etc.
