Apple Watch Security Features: It Knows When You're Wearing It

A logical question that has come up since Apple announced the pairing of its new smartwatch with its new mobile payment system has been how users can protect themselves should their Apple Watch get into the wrong hands.

This, it turns out, will not be an issue, as Cult of Mac reports that the device's sensors can tell when a user is wearing it on their wrist and when it is taken off - at which time the device locks down so it can't be used for mobile payments until a security code is entered.

While some may find the process annoying, it's good to know those few extra seconds ensure your security.

The device's battery life, however, could be an issue some users are not anticipating.

As the publication notes, while existing smartwatches including Pebble and MetaWatch can last up to a week, early indications suggest the Apple Watch will need to be charged every day - something that is even irking Apple, Re/Code reports. The report adds that the device's sealed back could mean users would have to completely replace it when the battery dies out.

With the Apple Watch being touted as something you can wear every day for every occassion, the daily charging could limit the device, which may be serving as an around-the-clock health and fitness monitoring service for some users. However, with the smartwatch's arrival not slated until early 2015, Apple still may have enough time to address the issue.

The smartwatch, which starts at $349, will work with iPhone models 5 and newer, meaning over 200 million current users can pair it with their iPhone. The watch will also feature mobile payment integration through Apple Pay.

"Because you wear it, we invented new intimate ways to connect and communicate directly from your wrist and it works seamlessly with iPhone," Apple CEO Tim Cook said. "And it's also a comprehensive health and fitness device."

The Apple Watch will come in two sizes and three collections, allowing users to customize the device to their unique needs for function and style.
