return the packaging

durable, reusableSeveral years ago, B’zT founder
Kiyeon Nam had what she recalls as
a terrifying experience: she briefly
lost her then 3-year-old daughter in
a mall. The incident spurred Nam to
research child- tracking devices and
then, finding the options lacking, to
create one of her own. B’zT’s trackingdevices—which won a 2019 Edison
Award—are machine- washable and
come embedded in kid-friendly T-shirts
and patches, which start at $19.99.
Parents and teachers can use the
company’s free app to monitor the
locations of kids wearing the devices.

A PHONE, PLAIN
AND SIMPLE
The Light Phone IIFor those who think time spent star-
ing at screens is doing more harm
than good, the $350 Light Phone II
provides a smartphone stripped
down to its essentials. The iPhone 4
look-alike can only call, text and set
an alarm —no camera, email or social
media, though features like a calcula-
tor and music playback are in devel-
opment. “It’s been incredible to hear
user feedback that people are feeling
more calm and content ... because
they weren’t scrolling through their
smartphones,” says co-founder Joe
Hollier. —Patrick Lucas AustinB’zT’s app
