From Videx, with the CyberKey Remote Validator, users can receive entry authorization each day at the exterior of a building or complex by inserting their key into the communication station. In high-security areas, or in applications with high personnel turnover, key control can be best achieved by setting a frequent expiration date in each user key, for example, at the end of each eight-hour work shift. With the ability to authorize keys on an as-needed basis, Remote Validator eliminates problems associated with lost keys and unauthorized entry. Plus, the system eliminates wrongful entry by someone using a key outside of an assigned work schedule, and prevents key duplication.
