Columbus Regional Airport Authority /global/scaled/5184x2255x15x577x1000x435/Other-assa-export-solutions-references-ref-airport.jpg The Columbus Regional Airport Authority (CRAA), which operates three airports in Columbus, Ohio, selected CLIQ® to secure its airports. An airport can measure hundreds of acres, with buildings containing thousands of doors to secure and unsecure areas. Thousands of people need to be assigned various authorization levels. “We have the CLIQ® system in administrative offices that store sensitive material,” says Christopher Hinds, manager of airport operations and aviation security. “Event logs show who had access to the office.” Since CRAA combines CLIQ® and ASSA’s Twin system, a building can have high-security mechanical cylinders in doors with lower security requirements, while electronic cylinders are used on doors needing greater security. If security needs change, it’s easy to expand the system.
