1. A security system for providing physical entry by a person into a secured area, the security system comprising:

  • an access door of the secured area;

    a lock that controls access into the secured area through the access door;

    a controller coupled to the lock;

    a radio frequency identification (RFID) card permanently located near the access door containing an identifier of the access door and an identifier of the security system;

    a portable wireless device, carried by the person proximate to the access door, that transmits a wireless entry request message or signal to the RFID card in response to activating, by the person, an access button on a screen of the portable wireless device, wherein the wireless entry request message or signal includes an identifier of the portable wireless device and the identifier of the security system; and

    a processor within the RFID card that compares the identifier of the portable wireless device and the identifier of the security system with one or more authorized identifiers, and, if both the identifier of the portable wireless device and the identifier of the security system match with the one or more authorized identifiers, wirelessly transmits an encrypted file including the identifier of the security system and the identifier of the access door back to the portable wireless device,wherein the portable wireless device decodes the identifier of the access door and the identifier of the security system from the encrypted file and wirelessly transfers an access request including the identifier of the access door, the identifier of the security system, and a personal identifier of the person carrying the portable wireless device to an access processor of the controller, andwherein the controller decodes the access request, compares the personal identifier of the person with a list of identifiers of persons authorized to enter the secured area of the security system, determines that the personal identifier of the person matches an identifier in the list of identifiers, confirms the identifier of the access door being part of the security system by matching the identifier of the access door with a list of door identifiers, and sends an activating message to the lock to activate the lock, thereby allowing physical entry by the person into the secured area in response to confirming the identifier of the security system, the identifier of the access door, and that the person carrying the portable wireless device is an authorized person.
