Tensor can supply Access Control and Visitor Management Systems (VMS) to businesses in order to increase their security. VMS is a low cost computer based Visitor Management and Visitor Pass production system. On arrival at a site, a full colour photograph is taken and personal details are recorded and digitally stored. Optionally, the visitor's fingerprint details can be electronically enrolled to provide a future check of their identity. Once the details are safely stored within the PC, an inexpensive bar coded pass is then issued containing a photograph, name and validation dates.
