In construction, radio-frequency identification devices, or RFIDs, are used for security purposes to monitor jobsites and track workers. At Peru's Port of Callao, the largest port on the Pacific side of South America, RFID technology is being used to avoid collisions between workers and loading equipment.
"In most ports all over the world, there has, for many years, been a problem to effectively separate the men from the machines," says Henrik Kristensen, APM Terminals chief executive in Callao, whose company worked with RFID manufacturer Avonwood Developments Ltd., U.K., to perfect the ZoneSafe proximity warning system at the port.
