Abstract

An apparatus is provided that includes an access door of a secured area, a lock that controls access into the secured area through the door, a controller coupled to the lock, and a portable wireless device proximate the door, wherein the portable wireless device wirelessly retrieves an identifier from the door and wirelessly transfers the identifier of the door and a personal identifier of a person carrying the portable wireless device to the controller, and wherein the controller compares the received personal identifier with a list of identifiers of persons authorized to enter the secured area, determines that the received personal identifier matches an identifier of the list of identifiers, and activates the lock, thereby allowing physical entry by the person into the secured area.

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, and

wherein 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.

2. The security system as in claim 1 wherein the controller further comprises the security system.

3. The security system as in claim 1 further comprising a wireless access point in communication with the controller that wirelessly connects the portable wireless device to the controller.

4. The security system as in claim 1 further comprising a processor of the portable wireless device that uses a near field communication protocol to exchange information with the RFID card and to recover the identifier of the access door and the identifier of the security system.

5. The security system as in claim 4 further comprises a decryption processor of the portable wireless device that decrypts the encrypted file from the RFID card using one or more encryption keys to recover the identifier of the access door and the identifier of the security system.

6. The apparatus as in claim 1 wherein the RFID card is embedded in a frame of the access door.

7. 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 (RF) 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 RF 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 RF 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 identifiers, wirelessly transmits an encrypted file including the identifier of the access door and the identifier of the security system back to the portable wireless device proximate the access door,

wherein the portable wireless device retrieves 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, and

wherein 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.

8. The security system as in claim 7 wherein the RF card further comprises a radio frequency identification (RFID) card located proximate the access door that provides the identifier of the access door and the identifier of the security system to the portable wireless device.

9. The security system as in claim 8 wherein the RFID card further comprises the encrypted file containing the identifier of the access door and the identifier of the security system.

10. The security system as in claim 9 wherein the RFID card further comprises a near field communication (NFC) card.
