The new locator band is waterproof, making it durable also in extreme weather conditions. A special tool must be used to remove the locator from one’s wrist – ensuring that children will not ‘escape’ easily. These measures help tighten security, so that the locator wristband is removed only when the parents decide it is no longer necessary. 

Although some parents may consider the device as a nuisance for the children, its minimal dimensions (38x50x16mm) and light weight (54 grams) make it appear and feel just like a regular wristband. The device makes used of two positioning systems, one based on GPS and the other based on GSM. The device also includes a clock and an alarm, enabling intransigent parents can set a return time for their children. 

According to Keruve, the unit’s Lithium-ion rechargeable battery will supply the necessary power for 3.5 days without recharging, while the locator’s battery should be sufficient for 2 days. Besides tracking children, the new GPS locator could be used for Alzheimer patients, who often get lost. The company has yet to announce the GPS locator’s price. 

TFOT covered the world’s smallest GPS tracker, VELO, developed by UK Company TariffMan, and the Nike+ Sportband athlete wristband, which collects information during running, jumping, or any other physical activity. Other related TFOT stories include the GPS photo finder, which allows users to easily find the location in which a picture was taken, and the Carbon Hero, a new device that uses GPS technology to track users' traveling distance, thus enhancing their awareness to their carbon footprint. TFOT has also covered two small object GPS tracking devices - RoamEO and Loc8tor.
