The Tensor Monitoring of Contractors and Visitor System, also called WinMCVS.NET, is a web-based software that enables better management of visitor monitoring within the site. Through the app on the computer or the internet browser, it is possible to book in advance the visitor meetings, both single and multiple day appointments, and with one or more participants. After reservation, all the parties receive an email with all the details about the appointment such as the date, the time, and location. Among the many features of this visitor management software, one that massively streamlines visitor control activities is the appointment diary. It displays the scheduled daily, weekly and monthly appointments, splitting out them in pending, late, or missed, allowing you to set new appointments and check-in or out visitors.
