FULLY ENGAGED: Employees of Zizai Technology at work on September 30

In today's fast-paced world it is easy to lose sight of essential details—a shortcoming one Beijing-based entrepreneur has sought to address with the invention of a novel kind of tracker.

Tian Lin, CEO of Beijing-based Zizai Technology Co. Ltd.

"The product helps customers find missing objects and reminds them not to forget to take important items such as keys before leaving home. It may also prevent children and pets from getting lost," Tian Lin, CEO of Beijing-based Zizai Technology Co. Ltd., told Beijing Review.

The tiny device developed by Tian's company was on display during the Second Beijing Cultural and Digital Industry Fair in late September. The event, hosted by the Beijing Municipal Government along with the Ministry of Industry and Information Technology, aimed to promote the latest products of small and medium-sized local hi-tech companies.

The tracker is a small sound device that can be triggered by smartphone Bluetooth. Users may attach it to their possessions such as keys, and download the Nut app from the company's website. When they cannot find their keys, they press a button on their app and the tracker will produce sounds to help them easily locate the keys. However, a precondition is that the keys and the mobile phone should be within 50 meters of each other—the effective range of Bluetooth. The second function of the tracker is that a user's phone will ring when the tracker and the phone are more than 50 meters apart, reminding the user that he or she has forgotten his or her keys.

Tian, who started his company in March last year, chose to create this gadget in order to meet the needs of those who are forgetful.

Tian said that people today are so busy that they often forget where they've put their things. It is his belief that a product that helps people look for lost things will be very useful in daily life and therefore have a sizable market.
