This Wristband Helps You Keep Track Of Your Kid

Jan 29, 2014

Keeping track of your kids at a theme park or fair can be a challenge. That’s why Plano parent and engineer Willy Wu created a device called BuddyTag. There’s no GPS involved -- just a phone and a wristband.

 The terror that sparked the idea

Willie Wu, BuddyTag inventor, in his Plano office.

A few years ago, Willie Wu lost his six-year-old, Bethany, at Six Flags in Arlington.

“It was scary, it was 10 minutes, it was bad,” he says.

Wu found her, at the gift shop, but those 10 minutes of terror stuck with him. That same night, he looked for kid safety devices online, but everything was GPS-based and cost more than $100, plus a monthly fee. That’s when he thought about using Bluetooth – the technology that links devices wirelessly and is built-in to most smartphones.

“I don’t need something that’s fancy,” Wu says, just something easy to use, “to alert me if my kid is too far away.”

That's when he began to develop BuddyTag.

BuddyTag features

BuddyTag is a child safety device that helps parents track their child when out and about.

Wu designed a variety of candy-colored, silicone wristbands that look a bit like watches. You slip a small electronic button into the bracelet and that button works with a free app to alert connected phones when a kid is out of proximity.

You can choose the alert tune, and customize the range – for Bluetooth, the maximum is around 120 feet.

There’s also a panic button, which kids can press to alert their parents if they’re in danger.

The wristbands are designed with aluminum coin-screw locks reinforced with Mylar so kids can’t rip them off, and inside each one there's a spot to write down contact information.

Helping Holly keep track

Holly Snow, who lives in Fairview, has six kids to keep track of. She says BuddyTag has come in handy at soccer games, when she wants to watch her older kid on the field, but the toddlers want to play on the sideline.
