Many people have questions about jewelry with GPS tracking. There are usually 2 reasons for this question:
When it comes to jewelry, there is a number of brands that offer jewelry with GPS capabilities. Cuff jewelry was founded by Deepa Sood. The Cuff collection includes necklaces, bracelets, and key chains. The brand announced that a fitness collection will be coming in 2016. All Cuff items are available in a variety of finishes and textures. Each jewelry piece has a slot for a small rectangular GPS recording sensor component called the “CuffLinc.” CuffLinc works as the alert system.
First, a user needs to install the Cuff app on his or her smartphone. Using the app, a user can set up a trusted network of friends that will be notified in case of an emergency. If the person wearing a piece of Cuff jewelry presses the CuffLinc activating button for three seconds or more, a smartphone sends a text message to the trusted network. Wearers of Cuff will know for sure that they’ve sent an alert, because when they do so, the jewelry vibrates.
Once an alert has been sent, people in the trusted circle can click on the link in the text message to be taken to the Cuff app. The app will show them the location of the person who pressed the button. Cuff GPS sensor works without any charging. There are no cords to plug in. Cuff sensor will stay charged for 6-12 months before it needs a replacement. It is important to understand that all the work is basically done not by jewelry, but by a smartphone: it is a smartphone that sends a message and tracks location. The jewelry insert basically serves as a remote panic button for a smartphone. Cuff jewelry connects to a smartphone using Bluetooth technology, so in order for it to work, the jewelry needs to be located within 20-30 feet of the smartphone it is paired with. The smartphone, in its turn, needs to be connected to the Internet, cellular service or Wi-Fi.
If you want to track someone with jewelry without them knowing, the situation is not so good. GPS location reader size is the biggest problem. There are no sensors on the market small enough to fit into a piece of jewelry yet. The size requirement comes from the fact that in order to be fully operational, a GPS device needs a power source. Product available on the market as “World’s Smallest GPS Device” is currently similar in size to half of a cigarette lighter. While there are GPS ring prototypes being developed, they have not hit the market yet.
