The Legoland theme park at Billund in Denmark now has the ultimate attraction — radio controlled kids.

The service is actually a very Nordic, serious-minded and responsible use of Wi-Fi based asset tracking to make sure parents don’t lose their children at the park. And it is accessed by mobile phone text messages.

Visitors to Legoland can hire a Kidspotter wristband, which includes a tag from Bluesoft Inc. If their children stray, the parents text the Kidspotter system and get back a text message, which includes the area the child is in and their exact coordinates on the map.
