One little-known risk when it comes to phone security is that an often-unlocked touch screen may have smudges showing the security code needed to access the device. SUNZs is a buckle for any wristwatch that has an NFC chip inside that can be tapped on the screen to unlock the phone, access key features, and can be programmed as a quick launcher for up to eight apps. The product is pitched in an infomercial style, and claims to be “the coolest and most useful tool ever,” which may be overstating things a bit. Of course, since it requires NFC, the iPhone is out for now. SUNZs is available in six colors, and will ship out in August for backers who pledge $13.
