Here’s a killer little gadget. The Bluetooth-powered nio Tag [$64.88] prevents the loss of your smartphone and other valuables. It’s the first Bluetooth-powered security tag. You simply attach the nio Tag to any item you want to keep track of while en route (i.e., luggage, briefcase, child, pet, etc.) or you can carry the nio Tag to secure a smartphone or iPad. Should you become separated from the item, an alarm will alert you – acting as a buddy system or an invisible, electronic leash.
