If you know when a visitor will be coming you may be able to arrange to get them a temporary credential before or when they arrive. If you have a guard or reception desk where visitors can report this may be a simple solution. If a visitor arrives unexpectedly, intercoms or phones can be used at a central entry point to allow the visitor to communicate with someone so they can be taken care of. Some systems will allow the person that the visitor calls to unlock a door through the phone. Visito management software is also available to handle different scenarios that may arise.
