Method and Apparatus for Upgrading Ink Stain Antitheft Tags with RFID Communications Function

Abstract

The invention provides an RFID circuit for use with new or pre-existing antitheft tags. An RFID pin replaces the current pin on antitheft tags that retailers already own. The RFID circuit is incorporated into or secured to, the pin structure. By replacing the current pin used on antitheft tags with a low cost RFID pin, existing antitheft tags can be inexpensively upgraded to antitheft tags that are also capable of use as inventory management and/or enhanced theft control devices.

Claims

1. A device for deterring theft of articles, comprising: a plurality of ampules; a permanent staining substance to be contained in said ampules, said permanent staining substance is of the type that changes the composition of the article; a housing which encloses said ampules, said housing comprising a base component supporting said ampules and a cover component to cover said base component, said cover component containing a break away element; a means to allow said permanent staining substance to escape if said ampules are fractured; and a pin extending from the housing, the pin further comprising an RFID circuit.

2. The device of claim 1, wherein said base component has a plurality of holes which allow said permanent staining substance to escape if said ampules are fractured.

3. The device of claim 2, wherein said means for attaching said device to the articles to be protected comprises an elongated pin type connecting unit.

4. The device of claim 3, wherein said base component has a centrally located hole which supports said elongated pin type connecting unit.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0028] Before discussing the figures, a brief overview of the invention will be provided. The invention provides an inexpensive way to upgrade ink-stain antitheft tags with RFID circuits such that pre-existing ink stain tags can also communicate with point of sales terminals, etc. The invention provides an upgrade to pre-existing ink stain antitheft tags in the form of an RFID pin that replaces the prior art securing pin. The RFID pin contains an RFID circuit that is incorporated into the securing pin. When an antitheft tag is upgraded, the prior art securing pin is replaced with an RFID pin. As a result, the upgrade pf a simple inexpensive part eliminates the necessity of replacing the entire ink stain antitheft tag with new antitheft tag. This substantially reduces the cost of adding new function to pre-existing antitheft tags. In large merchants, there may be a very large number of pre-existing tags in use, and as a result, the cost of replacing the entire tag inventory would be prohibitive. Of course, for new ink stain antitheft tags, the RFID pin would be installed at the point of manufacture. We turn now to a discussion of the figures.

[0029] FIG. 1 is a transparent bottom view of a prior art ink stain antitheft tag 1 with a securing clip 3 attached to the ink stain antitheft tag 1. In this embodiment, the body 2 of the antitheft tag 1 is shown with a securing clip 3 attached to the securing pin 5 (shown below in FIG. 2). For ease of illustration, the body 2 of antitheft tag 1 is shown as a transparent view to illustrate the location of the ink ampules 4 that are inside the body 2. In normal use, the securing pin 5 is inserted into an article 7 (shown below in FIGS. 6 and 8) to be protected and then secured to the article 7 by securing clip 3.

[0030] FIG. 2 is a transparent bottom view of the prior art ink stain antitheft tag 1 shown in FIG. 1 with the securing clip 3 removed to show the ink ampules 4 and the securing pin 5. In this figure, the antitheft tag 1 is shown having a substantially rectangular shape. However, those skilled in the art will recognize that any suitable shape can be used, such as circles, irregular shapes, etc. In prior art ink stain antitheft tags, the pin is placed in the antitheft tag such that if the tag is forcibly removed, the ink ampules will be broken and the ink released, As a result, the attached article is no longer usable by the thief.

[0031] FIG. 3 is a transparent edge view of the prior art ink stain antitheft tag 1 of FIGS. 1-2 with the securing clip 3 removed to show the ink ampules 4 and the securing pin 5. In this figure, the securing clip 3 is not shown. For ease of illustration, it should be understood that the shape, dimensions and size of the antitheft tag 1 can vary to suit design choices.

[0032] FIG. 4 is a transparent bottom view of a preferred embodiment of the ink stain antitheft tag 1 with the securing clip 3 removed and showing the ink ampules 4, the RFID pin 6. By replacing the prior art securing pin 5 with an RFID pin 6, a prior art antitheft tag 1 can be upgraded to an intelligent antitheft tag 1 that can transfer information to external devices, such as cash registers, point of sale terminals, theft detection devices, etc. As a result, merchants desiring to add new function, such as an RFID based inventory control function to their antitheft tags, can do so at minimal cost. Without the upgrade capability provided by the invention, the addition of the RFID feature would require a complete replacement of the antitheft tag 1 at much greater cost. For large merchant enterprises, using many thousands of these devices, the total cost can be significant.

[0033] FIG. 5 is a transparent edge view of an ink stain antitheft tag with the securing clip 3 removed and showing the ink ampules 4, and an RFID pin 6. For ease of illustration, the article 7 that is protected by the antitheft tag 1 is not shown in this figure.

[0034] FIG. 6 is a transparent edge view of an ink stain antitheft tag 1 showing the ink ampules 4, and a securing clip 3 that attaches to the RFID pin 6. In addition, the article 7 is also shown.

[0035] FIG. 7 is a transparent edge view of an alternative preferred embodiment of the ink stain antitheft tag 1 with the securing clip 3 removed and showing the ink ampules 4, and an RFID pin 6 with embedded RFID circuit 8.

[0036] FIG. 8 is a transparent edge view of the embodiment of FIG. 7 showing the ink stain antitheft tag 1 with the securing clip 3 attached and showing the ink ampules 4, the RFID pin 6 with an RFID circuit 8 embedded inside the RFID pin 6. Article 7 is also shown.

[0037] As can be seen from the foregoing, existing conventional antitheft tags 1 can be easily and inexpensively upgraded to a dual function antitheft tag that serves its original antitheft purpose while simultaneously providing an additional inventory management function. This is accomplished by merely replacing the prior art securing pin 3 with the enhanced RFID pin 6 provided by the invention. As a result, the merchant does not have to incur the costs of replacing the entire antitheft tag 1 when upgrading the merchant's system.

[0038] It should be noted that the antitheft tag 1 used in the foregoing embodiments was used for the purpose of describing the invention, but the invention can be implemented on any antitheft tag that uses a securing pin, such as the one shown, audible antitheft tags, ink based antitheft tags, etc.

[0039] While the invention has been described with respect to a preferred embodiment thereof, it will be understood by those skilled in the art that various changes in detail may be made therein without departing from the spirit, scope, and teaching of the invention. For example, the material used to fabricate the device can vary, etc. Accordingly, the invention herein disclosed is to be limited only as specified in the following claims.
