The co-founder of Apple Computer, Stephen Wozniak, has developed wireless location-monitoring technology that would use electronic tags to help people keep track of their animals, children or property.

WozNet is a simple and inexpensive wireless network that uses radio signals and global positioning satellite data to keep track of a cluster of inexpensive tags within a one- or two-mile radius of each base station and track the location of dozens or even hundreds of small wireless devices that can be attached to people, pets or property.
