Who's Who Around the Office
Keep track of who's coming & going for a safety's sake
Have a receptionist or security guard near the doors to welcome guest. Closed-circuit cameras and intercom systems may also be used with locked entrances, so that personnel can identify visitors before allowing them in.
Keep a visitors' log.
When visitors arrive, have them sign in and note their time of of arrival and who they're coming to visit. When they leave, make sure they log out and note what time they left.
Issue temporary badges to visitors.
Print brightly colored "VISITOR" stickers or badges for guest, so that they stand out.
Don't let visitors wander the facility escorted.
Have an employee accompany them to their destination and make sure they are not forgotten.
Require employee ID badges.
If your company is large enough that every employee may not know everyone else, issue photo badges for employees and contractors, so workers are easily identified.
