Abstract

A system and method for releasing a security tag from an article automatically at a point of sale without the need fro store employee involvement, assuming a valid sale is occurring. A system and method fro releasing a security tag from an article automatically at a point of sale that tracks the detacher operation and the time and date of such operation.

Claims (19)

1. A system for the automatic detachment of a security tag from an article at a point of sale, said system comprising:

a reader located at the point of sale that reads the security tag to identify the article being purchased;

a detacher, in communication with said reader, said detacher releasing the security tag from the article once said reader has read the security tag;
and a database, in communication with said reader, which stores the identity of said detacher when said detacher releases the security tag.
2. The system of claim 1, wherein said database stores the date and time when said detacher releases the security tag.
3. The system of claim 1, wherein said security tag comprises a locking mechanism that can only be activated by said detacher, independent of any human intervention.
4. The system of claim 3, wherein said locking mechanism comprises displaceable components containing small amounts of ferromagnetic material, said displaceable components being movable to release said locking mechanism only when subjected to magnetic field from said detacher that can interact with said ferromagnetic material to cause said components to be displaced.
5. The system of claim 4, wherein said detacher comprises a displaceable permanent magnet.
6. The system of claim 4, wherein said detacher comprises an electromagnet.
7. The system of claim 4, wherein said security tag comprises:

a first part comprising a pin having a free end, said free end being adapted to pass through the article; and a second part comprising said locking mechanism including a passageway for receiving said free end after it has passed through the article, thereby locking said security tag to the article.
8. The system of claim 1, wherein said reader is a transmitter/receiver pair that emits an interrogation signal.
9. The system of claim 8, wherein the security tag comprises:

a resonant circuit that is tuned to a frequency corresponding to said interrogation signal; and said resonant circuit emitting a response signal whenever said interrogation signal is received by said resonant circuit.
10. The system of claim 9, wherein said frequency is in the frequency range of approximately 5 kHz - 12 kHz.
11. The system of claim 9, wherein said frequency is in the frequency range of approximately 50 kHz - 70 kHz.
12. The system of claim 1, wherein said reader is a radio frequency (RF) reader that emits an interrogation signal.
13. The system of claim 12, wherein the security tag comprises:

an integrated circuit with a memory for storing an article identifier therein;

a resonant circuit coupled to said integrated circuit, said resonant circuit being tuned to a frequency corresponding to said interrogation signal;
and said integrated circuit emitting a response signal, via said resonant circuit, comprising said article identifier whenever said interrogation signal is received by said resonant circuit.
14. The system of claim 13, wherein said frequency is in the frequency range of approximately 100 kHz - 400 kHz.
15. The system of claim 13, wherein said frequency is in the frequency range of approximately 2 MHz - 14 MHz.
16. The system of claim 12, wherein the security tag comprises:

an integrated circuit with a memory for storing an article identifier therein;

an antenna coupled to said integrated circuit, said antenna being tuned to a frequency corresponding to said interrogation signal; and said integrated circuit emitting a response signal, via said antenna, comprising said article identifier whenever said interrogation signal is received by said antenna.
17. The system of claim 16, wherein said antenna is a dipole antenna.
18. The system of claim 17, wherein said frequency is the frequency range of approximately 850 MHz - 950 MHz.
19. The system of claim 17, wherein said frequency is the frequency range of approximately 2.3 GHz - 2.6 GHz.
