Description: A visitor log is a document or system that collects information about individuals entering a facility, such as office buildings, schools, hospitals, or events. This log may include data such as the visitor’s name, time of entry and exit, purpose of the visit, and, in some cases, contact information. The importance of a visitor log lies in its dual function of security and privacy. On one hand, it allows organizations to monitor who accesses their facilities, which is crucial for physical security and risk management. On the other hand, it also raises considerations about privacy and data protection, as the information collected must be handled responsibly and in accordance with data protection regulations. The implementation of a visitor log can be manual, using paper forms, or digital, through automated systems that facilitate data management and storage. In a world where security and privacy are increasingly relevant, a visitor log becomes an essential tool for balancing access to facilities with the protection of individuals’ personal information.
