Abstract

A secure access system and method is disclosed, the access system utilizing a powered secure card with access rights codes that allows an authorized user to gain access to an elevator, an area behind a door, or a particular floor in a building without requiring the user to retrieve the secure card and physically present the secure card to a sensor. Sensors in the access system communicate with a wireless transceiver in the secure card. Each sensor is capable of reading only the type of access code or codes that the sensor has been authorized for reading. A sequence of sensors for allowing or, denying access to areas or functions for the secure card increases security and prevents illicit copying of the access codes and duplication of the secure card.

Claims

1. An access control system comprising:

a powered secure card comprising a plurality of stored access codes;

an elevator exterior sensor for detecting the powered secure card, for reading an elevator access code from the powered secure card, and for summoning an elevator car if the elevator access code is authorized; and

an elevator interior sensor inside the elevator car for reading a floor access code from the powered secure card and for instructing the elevator car to travel to a floor represented by the floor access code if the floor access code is authorized.

2. The access control system of claim 1, the elevator interior sensor also detecting how many occupants are in the elevator car.

3. The access control system of claim 1, the elevator interior sensor determining if a number of occupants equals a number of powered secure cards and if the number of occupants is more than the number of powered secure cards instructing the elevator car to remain stationary.

4. The access control system of claim 1, further comprising:

a door exterior sensor for detecting the powered secure card, for reading a door access code stored in the powered secured card, and for allowing access to a door controlled by the door exterior sensor if the door access code is authorized.

5. The access control system of claim 1, further comprising:

a door interior sensor for detecting a user in close proximity to the door interior sensor, detecting if there is a powered secure card presently with the user, and notifying the user that the user does not presently have a powered secure card.

6. The access control system of claim 5, the door interior sensor controlling a door to remain unlocked after notifying the user that the user does not have a powered secure card.

7. The access control system of claim 1, the powered secure card further comprising:

a wireless transceiver for communicating with wireless transceivers in sensors.

8. An access control system and method comprising:

detecting a powered secure card by an elevator exterior sensor;

reading, by the elevator exterior sensor, an elevator access code stored in the powered secure card;

summoning, by the elevator exterior sensor, an elevator if the elevator access code authorizes a user of the power secure card to use the elevator;

reading, by an elevator interior sensor, a floor access code stored in the powered secure card; and

traveling, by the elevator, to a floor of a building represented by the floor access code if the floor access code is authorized.

9. The access control system and method of claim 8, further comprising:

detecting a powered secure card by a door exterior sensor;

reading, by the door exterior sensor, the door access code from the powered secure card; and

instructing, by the door exterior sensor, a door controlled by the door exterior sensor to unlock if the door access code is authorized.

10. The access control system and method of claim 8, further comprising:

detecting, by a door interior sensor, a user in close proximity to the door interior sensor;

detecting, by the door interior sensor, if there is a powered secure card presently with the user; and

notifying, by the door interior sensor, the user that the user does not presently have a powered secure card.

11. The access control system and method of claim 10, further comprising:

controlling, by the door interior sensor, the door to remain unlocked after notifying the user that the user does not presently have a powered secure card.

12. The access control system and method of claim 8, further comprising prior to reading the elevator access code:

requesting, by the elevator exterior sensor, to read an elevator access code stored in the powered secure card;

determining, by the powered secure card, if the elevator exterior sensor has authorization to read the elevator access code; and

allowing, by the powered secure card, the elevator exterior sensor to read the elevator access code if the elevator exterior sensor has authorization to read the elevator access code.

13. The access control system and method of claim 8, further comprising prior to reading the floor access code:

requesting, by the elevator interior sensor, to read a floor access code stored in the powered secure card;

determining, by the powered secure card, if the elevator interior sensor has authorization to read the floor access code; and

allowing, by the powered secure card, the elevator interior sensor to read the floor access code if the elevator interior sensor has authorization to read the floor access code.

14. The access control system and method of claim 8, further comprising:

detecting, by the elevator interior sensor prior to reading the floor access code, how many occupants are in the elevator.

15. The access control system and method of claim 14, further comprising:

determining, by the elevator interior sensor prior to reading the floor access code, if a number of occupants is more than a number of powered secure cards and if the number of occupants is more than the number of powered secure cards instructing the elevator to remain stationary.

16. The access control system and method of claim 8, where the elevator interior sensor and the elevator exterior sensor both comprise wireless transceivers for communicating with a wireless transceiver in the powered secure card.

17. An access control system and method comprising:

detecting a powered secure card by an elevator exterior sensor;

requesting, by the elevator exterior sensor, to read an elevator access code stored in the powered secure card;

determining, by the powered secure card, if the elevator exterior sensor has authorization to read the elevator access code;

allowing, by the powered secure card, the elevator exterior sensor to read the elevator access code if the elevator exterior sensor has authorization to read the elevator access code;

reading, by the elevator exterior sensor, the elevator access code from the powered secure card;

summoning, by the elevator exterior sensor, an elevator car if the elevator access code authorizes a user of the powered secure card to use the elevator;

detecting a powered secure card by an elevator interior sensor;

requesting, by the elevator interior sensor, to read a floor access code stored in the powered secure card;

determining, by the powered secure card, if the elevator interior sensor has authorization to read the floor access code;

allowing, by the powered secure card, the elevator interior sensor to read the floor access code if the elevator interior sensor has authorization to read the floor access code;

reading, by the elevator interior sensor, the floor access code from the powered secure card; and

instructing, by the elevator interior sensor, the elevator car to travel to a floor of a building represented by the floor access code.

18. The access control system and method of claim 17, further comprising:

detecting, by the elevator interior sensor, how many occupants are in the elevator prior to requesting to read the floor access code stored in the powered secure card.

19. The access control system and method of claim 18, further comprising:

determining, by the elevator interior sensor, if a number of occupants is more than a number of powered secure cards and if the number of occupants is more than the number of powered secure cards instructing the elevator to remain stationary.

20. The access control system and method of claim 17, further comprising:
