Description

  The present invention is a radio frequency identification (RFID) tag that can be attached to a product or the like and can write / read individual data of the product or the like to be identified without contact. The present invention relates to an RFID tag with an illegal take-out detection function for detecting take-out without any reason.

  Conventionally, distribution merchandise management is performed by attaching a tag filled with individual identification data of various merchandise and the like to the merchandise and the like and distributing it in the market. For example, we often see barcode data and print data displayed on tags, labels, or packaging containers attached to products.

  In general, products and the like are manufactured in factories and supplied to consumers via wholesalers and retail stores. These products, etc. are distributed and managed with data related to individual products such as product code, size display, brand display, etc. Usually, paper or plastic tags filled with these data are attached to the products etc. Has been.

  In manufacturing plants for products, etc., tags with product codes, size indications, brands, etc. displayed on the products are attached to appropriate parts of the products, etc., and shipping management is performed based on the displayed contents of the tags. ing. In the wholesaler, acceptance inspections, sorting of retail stores, and the like are performed based on the display contents of the tags. Further, in retail stores, inventory management of products, order management, and the like are performed based on the display contents of tags in the same manner.

  In order to process the inventory management, order management, etc. of this product mechanically quickly, it can be attached to the product etc., and individual data of the product etc. that are identification objects can be written / read out in a non-contact manner. It is suitable to use an RFID tag that can be used as the tag (for example, Patent Document 1).

  On the other hand, it is attached to a product, etc., moves with the product, and is detected when it passes through a predetermined gate, thereby managing the product and preventing theft of the product (so-called shoplifting). A tag [EM (Electro Magnetic) tag] is known. The detection tag is attached to a product that needs to be managed in advance. When you purchase this product properly, change the function of the tag at the toll gate, etc., so that you can distinguish the product that you have paid for when you pass through the gate from the illegally taken-out product (shoplifted product) (For example, patent document 2).

However, if the RFID tag has an unauthorized take-out detection function, it is necessary to attach the RFID tag and the detection tag separately, and it is particularly difficult to attach and attach an expensive small product that is easily shoplifted. Note that when the RFID tag is not attached by attachment, the attachment is unstable, and the IC chip in the RFID tag may be damaged depending on the operating environment.

  While various studies have been made by the present inventors to solve the above problem, the identification target and the RFID tag are connected by a magnetic method (EM) wire, so that two pieces of the RFID tag and the detection tag are connected. It was learned that there was no need to attach them separately and that the RFID tag could have an unauthorized removal detection function.

  In addition, when an RFID tag is formed by pouching or laminating an RFID label with an IC chip and an antenna circuit attached thereto using a substrate such as a transparent plastic plate, even under an operating environment that does not normally occur, The present inventors have learned that it is possible to prevent damage to the IC chip and / or the antenna circuit in the RFID tag, and the present invention has been completed.

  Accordingly, an object of the present invention is to provide an RFID tag with an unauthorized take-out detection function that solves the above-described problems.

  The present invention for achieving the above object is described below.

  [1] A radio frequency identification tag including a base having an attachment hole formed thereon and a radio frequency identification label attached to the base, and a magnetic wire inserted in the attachment hole for connecting the base and the identification target A radio frequency identification tag with an illegal removal detection function consisting of

  [2] The radio frequency identification tag with a fraudulent take-out detection function according to [1], wherein the attachment hole of the magnetic wire is formed outside the region where the IC chip and the antenna circuit are formed in the radio frequency identification tag.

  [3] The radio frequency identification tag with a fraudulent take-out detection function according to [1], wherein the magnetic wire has connection means that make a pair with each other at both ends thereof.

  [4] The radio frequency identification tag with a tampering detection function according to [1], wherein the radio frequency identification tag is a pouch structure formed of a base and a radio frequency identification label.

  [5] The radio frequency identification tag with a fraudulent take-out detection function according to [1], wherein the radio frequency identification tag has a laminate structure formed of a substrate and a radio frequency identification label.

  [6] The radio frequency identification tag with a tampering detection function according to [1], wherein the connection form between the base body and the identification object using a magnetic wire is a lowering tag form.

  According to the present invention, since the identification object and the RFID tag are connected by the magnetic system wire, there is no need to attach the RFID tag and the detection tag separately to the identification object, and the RFID tag is illegally taken out. A detection function can be provided.

  In addition, according to the present invention, when pouching or laminating is performed on the RFID label as necessary, it is possible to prevent damage to the IC chip and / or the antenna circuit in the RFID tag even in a poor operating environment.

  Hereinafter, the RFID tag with unauthorized take-out detection function of the present invention will be described in detail by taking as an example a case where it is used in an unauthorized take-out detection system for products.

  FIG. 1 is a schematic view showing an example of an RFID tag with an unauthorized take-out detection function of the present invention. FIG. 2 is a conceptual diagram showing the unauthorized take-out detection system. In FIG. 1 and / or 2, reference numeral 2 denotes an RFID tag with an illegal take-out detection function, which connects the RFID tag 4 and the magnetic tag that reacts to magnetism (hereinafter referred to as EM wire) to connect the RFID tag 4 and the identification object 6. 8).

  As shown in FIG. 1, the RFID tag 4 is subjected to a processing process in which an RFID label 14 to which an IC chip 10 and an antenna circuit 12 are attached is sandwiched by a base 16 such as a transparent plastic plate and bonded and covered. A so-called pouch structure is formed. By forming this pouch structure, it is possible to prevent the IC chip 10 and / or the antenna circuit 12 in the RFID tag 4 from being damaged even in an operating environment that does not normally occur.

  A mounting hole 18 for the EM wire 8 is formed outside the region where the IC chip 10 and the antenna circuit 12 are formed in the RFID tag 4. Specifically, the RFID tag 4 is formed using a base 16 such as a transparent plastic plate wider than the RFID label 14. With this configuration, the RFID tag 4 is formed with a portion without the RFID label 14. Since the IC chip 10 and the antenna circuit 12 are not present in the portion where the RFID label 14 is not provided, the IC chip 10 and the antenna circuit 12 in the RFID tag 4 are damaged even if the EM wire mounting hole 18 is formed in this portion. It will not be done.

  The EM wire 8 has connecting means 20a and 20b that make a pair at both ends. The EM wire 8 is made of a soft magnetic material such as amorphous metal as a core material. Soft magnetic materials have high magnetic sensitivity and are sensitive when passing through the gate. That is, the EM wire 8 has a high unauthorized take-out detection function even if its size is small. The EM wire 8 having a small size does not occupy a space for mounting the mounting hole 18, and as a result, the size of the RFID tag 2 with an unauthorized removal detection function can be reduced.

  It should be noted that by covering the soft magnetic core material with a colorful coating so as to have a decorative property, it is possible to provide concealment to the fact that the EM wire 8 has an unauthorized removal detection function.

  The connection form between the identification object 6 and the RFID tag 4 by the EM wire 8 can take the form of a tag. This lowering tag form is particularly preferable in the case where the identification object 6 is an expensive small product that is easily shoplifted, such as a jewel, a ring, or a watch, because it can be easily mounted and is not easily removed in an operating environment such as a storefront.

  As described above, the RFID tag 2 having the IC chip 10 and the antenna circuit 12 and the unauthorized take-out detection function having the EM wire 8 is an inventory management, order management, etc. capable of non-contact writing / reading of individual data such as products. And a fraudulent take-out detection function.

  In FIG. 2, 22 is a fraudulent take-out detection gate, which is erected on the wall of the exit of a store in the building. As a gate detection method, a magnetic gate (EM gate) is used.

  Reference numeral 24 denotes a recording device provided in a fee payment place (counter) in the store. At this counter, the product taker 26 pays for the purchased product. At this time, the recording content of the RFID tag 4 attached to the identification object 6 is changed by the recording device 24, management data is collected, and the EM wire 8 is detected by the unauthorized take-out detection releasing means 28 such as a bag. The RFID tag 2 is separated from the identification object 6 and left on the counter. As a result, the identification object 6 is released from the unauthorized take-out detection function.

  By performing the unauthorized take-out detection canceling process, the EM gate 22 does not generate an unauthorized take-out detection signal even if the identification object 6 passes through the EM gate 22. On the other hand, if the price of the product has not been paid (if the product is to be taken out illegally), the illegal takeout detection function of the EM wire 8 attached to the identification object 6 has not been released. When passing 22, an unauthorized take-out detection signal is generated to detect unauthorized take-out.

It is the schematic which shows an example of the RFID tag with a tampering detection function of the present invention. It is a conceptual diagram which shows an example of the unauthorized carrying-out detection system of goods using the RFID tag with a unauthorized taking-out detection function of this invention.
