Abstract

There are provided an identification and surveillance device, a system and a method using active RFID technology to accurately and automatically track inventory at the item-level across the supply chain in real-time and at a distance. The device is provided with an attaching device for attaching to the item and a radio-frequency device securely mounted with the attaching device. The radio-frequency device comprises storage for storing data therein, the data comprising individual tag-related information, a transmitter, an antenna and a power source for powering the device. The radio-frequency device, with the help of the transmitter, is able to communicate with a corresponding radio-frequency receiver for tracking the item.

5. The device according to claim 1, wherein said radio-frequency device comprises an active chip operatively connected to the power source and a passive chip.

6. The device according to claim 1, wherein said radio-frequency device comprises a motion sensor for detecting motion of the inventory item, the radio-frequency device operating in a dual-transmission interval mode, a longer transmission interval detection when the item is stationary and a shorter transmission interval detection when the item is in motion.

7. The device according to claim 1, wherein said identification and surveillance device further comprises a global positioning system embedded therein.

8. The device according to claim 1, wherein said tag-related information comprises a unique pre-programmed identification code.

9. The device according to claim 1, wherein said radio-frequency device communicates with the corresponding receiver in a frequency range between Low Frequency and Micro Frequency, within approved radio spectrum frequency allocations.

10. The device according to claim 1, wherein said radio-frequency device communicates with the corresponding receiver at a frequency of 433 MHz.

11. The device according to claim 1, wherein said attaching device is provided with an anti-tamper and an anti-theft mechanism.

12. An identification and surveillance system for independently tracking a plurality of individual inventory items, said system comprising:

a plurality of identification and surveillance devices, each of said devices being attachable to a respective one of said plurality of items and comprising;

an attaching device for attaching to a corresponding item; and

an active radio-frequency device securely mounted with said attaching device, said radio-frequency device comprising;

storing means for storing data therein, said data comprising individual tag-related information;

a transmitter;

an antenna; and

a power source for powering said active radio-frequency device;

wherein each radio-frequency device, with the help of its transmitter, is able to communicate with a corresponding radio-frequency receiver for tracking one of said items and for providing loss prevention information in response to a potential loss event without requiring an interrogating signal, said loss prevention information including a time stamp, and wherein each attaching device and its active radio-frequency device are reusable;

a radio-frequency receiver capable of communicating with each of said active radio-frequency devices for receiving each of said corresponding data; and

a software product suite with application software loaded into a host computer and adapted to read, process and store each of said data with the help of said radio-frequency receiver for tracking each of said corresponding inventory items.

13. The system according to claim 12, wherein the radio-frequency device comprises a firmware provided with an anti-collision algorithm for allowing identification of a plurality of identification and surveillance devices by the radio-frequency receiver at the same time.

14. The system according to claim 12, the system being implemented in a retail store environment.

15. The system according to claim 14, the system providing an automated physical inventory of said retail store environment.

16. The system according to claim 14, further comprising additional radio-frequency receivers distributed in said retail store environment for tracking a presence of each of the radio-frequency devices.

17. The system according to claim 14, wherein the retail store environment comprises a plurality of distinct zones, the system further comprising additional radio-frequency receivers distributed in said zones for providing zoning information and for tracking a presence of each of said radio-frequency devices.
