colinneagle writes "A lot of people don't password-protect their smartphones, and even those who do employ a simple four-digit passcode to at least keep it a little convenient. Their phones aren't really protected, as the National Institute of Standards and Technology (NIST) recommends a 12-character random password. Those who check smartphones 50 times a day would probably get tired of that. So Motorola developed the Skip, an NFC-based unlocking tool smartphone users can clip to their clothes. Tapping an NFC-enabled phone to the Skip unlocks it. The Skip also comes in sticker form, so users can install one in their cars or at their desks." That's why the muggers want your jacket, too.
