There are plenty of smart wearable devices that simply track your daily activity. The mBand is designed to serve as your personal security device. Wrapped around your finger, this ring comes with a Bluetooth connected button to send alerts with your exact GPS location to an emergency response center.
The mBand ring lets you get help when in trouble. It has a failsafe mechanism to make sure you don’t activate it accidentally. You can use the ring to alert both the police and your contacts in case of an emergency. More information is available on Kickstarter.
