Worry about losing something important, like your keys, pet, or kid? Samsung wants to help give you peace of mind.

The company on Monday unveiled Connect Tag, a small, cellular-connected fob that lets you keep track of loved ones and valuables. Samsung said this is the first consumer mobile product to use narrowband technology (aka NB-IoT or Cat.M1), a "specially designed cellular communication standard for small data utilization, low power consumption, and the ability to securely connect to the Internet for optimal location services."

Samsung is planning to initially launch the Connect Tag in Korea before expanding it to additional countries in the coming months.

The device works with GPS, Wi-Fi-based positioning, and Cell ID technologies to fetch location information both indoors and outdoors. Measuring just 4.21 cm wide and 1.19 cm thick, Connect Tag is water and dustproof and lasts a full week on a single charge.

"It can be attached to a young child's backpack so his or her whereabouts can be tracked, clipped to a dog's collar so it won't go missing, and secured to keys so they are never lost," Samsung wrote in a news release.

It also works with Samsung's SmartThings ecosystem to enable some cool, futuristic experiences. You can, for instance, set up your Connect Tag to trigger specific smart devices like lights or your TV to turn on when you approach your home. Or, you can set up a geo-fence around your kid's school so you get a notification on your phone when they arrive or leave that area.

The device will send "periodic location notifications," letting you track your loved one's location record for peace of mind. There's also a "Send my location" function that lets your loved one easily beam you their current location. This way, "even a young child can let you know exactly where he or she is and [you] can go pick him/her up safely," Samsung wrote.
