Abstract

A theft prevention system includes an RFID reader configured to read an RFID tag to authenticate access to a predefined area, a laser scanner configured to scan the predefined area and detect an object in the predefined area, and a security component configured to initiate a security action when the detected object is at least one of an unauthenticated object and an unauthorized object.

Claims

1. A theft prevention system, comprising:

an RFID reader configured to read an RFID tag to authenticate access to a predefined area;

a laser scanner configured to scan the predefined area and detect an object in the predefined area; and

a security component configured to initiate a security action when the detected object is at least one of an unauthenticated object and an unauthorized object,

wherein the laser scanner is configured to be activated with an authorized individual being within the predefined area, and the security component is configured to initiate the security action when the authorized individual is no longer detected as being within the predefined area and the RFID reader has not detected exit from the predefined area by the authorized individual.

2. The system of claim 1, wherein the laser scanner has a scan zone, and the predefined area comprises a secure zone defined within the scan zone.

3. The system of claim 2, wherein the RFID reader has a read zone.

4. The system of claim 3, wherein the read zone is established at an access point to the secure zone.

5. The system of claim 1, wherein the RFID tag is associated with an individual having authorized access to the predefined area.

6. The system of claim 5, wherein the RFID tag is configured to be on the person of the individual having authorized access to the predefined area.

7. The system of claim 5, wherein the RFID reader is configured to monitor entry into and exit from the predefined area by the individual having authorized access to the predefined area.

8. The system of claim 1, wherein the laser scanner is configured to be inactivated in response to an authorized individual being within the predefined area.

9. The system of claim 1, wherein the laser scanner comprises a time-of-flight laser scanner.

10. A theft prevention system, comprising:

a laser scanner having a scan zone and a secure zone defined within the scan zone;

an RFID reader having a read zone;

an RFID tag associated with authorized access to the secure zone; and

a security component associated with the laser scanner and the RFID reader,

wherein the laser scanner scans the secure zone to detect an object in the secure zone,

wherein the RFID reader reads the RFID tag to authenticate access to the secure zone, and

wherein the security component initiates a security action when at least one of the object detected in the secure zone is unauthorized for access to the secure zone and the object detected in the secure zone is unauthenticated for access to the secure zone,

wherein the object comprises an individual having authorized access to the secure zone, and the security component initiates the security action when the authorized individual is no longer detected as being within the secure zone and the RFID reader has not detected exit from the secure zone by the authorized individual.

11. The system of claim 10, wherein the read zone of the RFID reader is established at an access point to the secure zone of the laser scanner.

12. The system of claim 10, wherein the RFID tag is associated with an individual having authorized access to the secure zone.

13. The system of claim 12, wherein the RFID tag is to be on the person of the individual having authorized access to the secure zone.

14. The system of claim 12, wherein the RFID tag is read by the RFID reader to monitor entry into and exit from the secure zone by the individual.

15. The system of claim 10, wherein the object comprises an individual having unauthorized access to the secure zone.

16. The system of claim 10, wherein the object comprises an authorized object.

17. The system of claim 10, wherein the object comprises an unauthorized object.

18. A theft prevention method, comprising:

reading an RFID tag to authenticate access to a predefined area;

scanning the predefined area to detect an object in the predefined area; and

initiating a security action when the object detected in the predefined area is at least one of an unauthenticated object and an unauthorized object, including initiating the security action when an authorized individual as the object detected in the predefined area is no longer detected within the predefined area and reading of the RFID tag to detect exit from the predefined area by the authorized individual has not occurred.
