Methods, systems, and computer program products for providing time-limited calendar based passcode access to areas, buildings and/or rooms

A system for administering limited-time visitor access passcodes, comprising:

• a computer network with at least one computer having a visitor requestor portal for allowing a user to request visitor access to a restricted area, wherein the visitor requestor portal is configured to allow users to electronically request visitor access for at least one specified visitor to at least one specified location associated with a restricted area on a campus, building, floor, office or room, on a specified date and time in advance of a requested visit time;
• a calendar-based access server in communication with the computer network, the calendar-based access server and/or the computer network configured to generate a time-limited visitor passcode to allow user access to the restricted area in response to a user placing a request for visitor access using the visitor requestor portal;
• a security server in communication with the calendar-based access server and/or the computer network;
• and
• at least one security passcode entry device in communication with the security server and/or the computer network that controls access to at least one restricted access area.

A computer program product for providing time-limited calendar-based access to restricted areas, comprising:

• a non-transitory computer readable storage medium having computer readable program code embodied therein, the computer readable program code comprising:
• computer readable program code configured to generate a time-limited access passcode that is operational for a security system for a limited time duration;
• computer readable program code configured to allow a user to request visitor access to a meeting site in a restricted area at a planned meeting time and date for at least one specified meeting participant using a computer network;
• computer readable program code configured to transmit the generated access passcode to the at least one meeting participant over the computer network;
• computer readable program code configured to accept the access passcode in a security entry control device in communication with the security system to allow a user with the access passcode a time-limited entry to a restricted area;
• and
• computer readable program code configured to reject the access passcode to the restricted area using the security entry control device on a date after a certain time or expiration of a certain time period associated with the planned meeting time and date.
