Abstract

An apparatus including 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, a portable wireless device proximate the door, the portable wireless device wirelessly retrieves an identifier from the door, wirelessly transfers the identifier of the door and a personal identifier of a person carrying the portable wireless device to the controller, 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 allowing physical entry by the person into the secured area.

Claims

1. An apparatus comprising:

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;

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

a portable wireless device, the portable wireless device wirelessly recovers the identifier of the door from the RFID card, wirelessly transfers the identifier of the door and a personal identifier of a person carrying the portable wireless device to the controller, 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 allowing physical entry by the person into the secured area.

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

3. The apparatus as in claim 1 further comprising a wireless access point that connects the portable wireless device to the controller.

4. The apparatus 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 door.

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

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

7. An apparatus comprising:

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, the portable wireless device wirelessly retrieves an identifier from the door, wirelessly transfers the identifier of the door and a personal identifier of a person carrying the portable wireless device to the controller, 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 allowing physical entry by the person into the secured area.

14. The apparatus as in claim 7 wherein the controller further comprises a security system.

15. The apparatus as in claim 7 further comprising a wireless access point that connects the portable wireless device to the controller.

8. The apparatus as in claim 8 further comprising a radio frequency identification (RFID) card located proximate the door that provide the door identifier to the portable wireless device.

9. The apparatus as in claim 8 wherein the RFID further comprises an encrypted file containing the door identifier.

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

11. The apparatus as in claim 10 further comprising a processor of the portable wireless device that operates under a near field communication (NFC) protocol

12. The apparatus as in claim 11 wherein the portable wireless device further comprises one or more private or public and private encryption keys saved in memory.

13. The apparatus as in claim 12 further comprising a decryption key that decodes the identifier of the door from an encrypted file retrieved from the NFC card.

16. An apparatus comprising:

a security system that protects a secured area;

an access door of the secured area;

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

a controller coupled to the lock;

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

a portable wireless device, the portable wireless device wirelessly recovers the identifier of the door directly from the RFID card; and

a wireless access port, wherein the portable wireless device wirelessly transfers the identifier of the door and a personal identifier of a person carrying the portable wireless device to the controller through the wireless access port, 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 allowing physical entry by the person into the secured area.

17. The apparatus as in claim 16 wherein the RFID card further comprises a near field communication (NFC) card.

18. The apparatus as in claim 17 wherein a processor of the portable wireless device exchanges messages with the NFC card under a NFC protocol.

19. The apparatus as in claim 16 wherein the RFID card further comprises an identifier of the door and an identifier of the security system encrypted with one or more of a private key and public and private keys.

20. The apparatus as in claim 19 wherein the portable wireless device further comprises one or more of a private key and public and private keys saved in a memory of the portable wireless devices that are used to decrypt the door and security system identifier.
