Solving real problems is a good foundation for entrepreneurs. And finally finding what we are looking for is something we all like. StickNFind is a promising solution built on Bluetooth technology together with IOS and Android. You simply put your very small Bluetooth stickers on your keys, pets, children backpacks or whatever you want to keep an eye on. The receivers are similar in size as a quarter-dollar coin and quite thin. The replaceable battery lasts for about a year. When you use the StickNFind mobile app to find things you can even light the label up and make it vibrate to help localize the item. But you can only locate things about 30 meters away. One can also use StickNFind to tell when tagged things are coming within range like the bag at the airport convey belt or getting out of range like your turtle trying to escape. Two labels are sold for $35 US but you can have many more managed from one phone.
