Abstract
For tracking a person such as a security guard at a construction site, RF-ID tags are placed at a plurality of locations at the site. The person carries a portable RF-ID tag reader while visiting at least some of the locations, and the portable RF-ID tag reader detects the presence of the RF-ID tags at these locations and reads tag identifiers identifying these locations. The person is tracked by monitoring a sequence of the tag identifiers read by the portable RF-ID tag reader. For example, the person also carries an Internet capable cell telephone that transmits the tag identifiers over the Internet to a computer at a location remote from the site, and the computer detects when the person deviates from an assigned path at the site.
