Description

  Use of IC tags attached to brands such as papers such as cash vouchers, forms, securities, banknotes, cash cards, credit cards, bags, watches, etc. that require authenticity judgment This is a technique related to a reading device and a manufacturing method.

  The use of IC tags of a size smaller than a grain of rice is attracting attention because it can be put into papers and kept inside leather, and the appearance of articles is not impaired.

  The current IC tag is intended to indicate the attribute and ID of the article to which it is attached, and has high reliability. Therefore, it is not assumed that it is misused. Even in the case of an IC tag having a size smaller than that of a grain of rice, it can be easily detected in which part of paper, bag, etc., it is embedded by light or X-rays. Therefore, the abuser can take out the IC tag from regular papers, bags, etc. and embed it in a fake, so that the reader can determine that the fake is a genuine product.

  Therefore, the dummy IC tag is embedded in paper or a bag together with the regular IC tag.

  The abuse of the regular IC tag can be prevented.

  There are two types of IC tags: contact type, non-contact type (wireless type), read-only type, and read / write type. Although the present invention is not particularly limited, a non-contact type is preferable for use in the present invention as being embedded in paper or a bag, and a read-only type is preferable for use in the present invention for determining correctness.

  A regular IC tag in which a number assigned in advance to paper or a bag is recorded is prepared. For example, if it is a banknote as papers, the IC tag in which the allocation number 0000000-000001000 (binary system) was recorded is prepared as regular IC. On the other hand, an IC tag having an assigned number of 10000000 to 10001000 (binary system) is prepared as a regular IC for a bag of a specific brand. Then, as a dummy IC tag, an IC tag in which assignment numbers 1110000 to 11001000 (binary system) are recorded is prepared. In this way, if different numbers are assigned to the regular and dummy, the reading device can determine the authenticity by reading the IC tag in the normal assigned number range. A dummy IC tag whose number cannot be read may be used. For example, if the IC tag manufacturing process determines that the number cannot be read, it will be reused as a defective product, and the manufacturing yield will be substantially 100%. Get closer. If the appearance or shape of the dummy when viewed using light or X-rays is the same as the regular one, the abuser cannot easily find the regular IC tag. For this reason, it is necessary to take out a plurality of IC tags including a dummy from paper or a bag and embed them in a fake, and a plurality of IC tag removal marks remain on regular paper or a bag. If there are many removal marks, the brand bag or the like will no longer be usable, and the present invention using the dummy IC tag can prevent the abuse of the IC tag. This is especially true if dummy IC tags are randomly placed in papers or bags. Although a conventional defective product can be said to be a good product as a dummy IC, it is referred to as a “defective product” in the present application.

  A reading device that reads an IC tag such as paper or a bag reads not only the number of a regular IC tag but also the number of a dummy IC tag. Therefore, just because the number read first is the number of the dummy IC tag, it should not be output that it is a fake only by looking at it. It must be configured to output that it is a fake only after confirming that all IC tags of the reading object are not within the number range of the regular IC tag. Therefore, for example, if the object to be read is a bag, a plurality of IC tags of one bag are sequentially read by a reading apparatus in which the assignment numbers 10000000 to 10001000 are registered, and the presence of a regular IC tag within the range of the assignment numbers In this case, the fact that it is a genuine product is immediately output. In this case, it is not necessary to read the remaining dummy IC tags, and correctness determination can be made quickly. Of course, after reading all the IC tags, it may be output whether it is a genuine product or a fake product. As an example of a specific operation of the reading device, the reading button is pushed when scanning the reading object, and while the reading button is continuously pressed, the reading operation is performed for one reading object, and until the button is opened. If the presence of the regular IC tag is not found, an output indicating that the read target is a fake is output. If a regular IC tag is found while the button is kept pressed, a message indicating that the product is genuine is immediately output.

  When the object to be read is paper such as banknotes, the reading device is provided with a supply unit that supplies a large amount of paper to the reading unit one by one with a feeder or the like. Since it is necessary to perform association, a determination unit is further provided for determining whether or not one reading target has been read by the reading unit in order to set a break from the next one. This reading apparatus incorporates computer software as determination means for determining whether the numbers read from a plurality of IC tags included in one sheet to be read are all different from the assigned numbers to be read. What is determined to be a fake as a result of the determination must be classified as a regular one. Therefore, the reading apparatus determines that the number read from the plurality of IC tags included in one sheet to be read is different from the number assigned to the paper by the determination unit. Sorting means for sorting one sheet into an abnormal tray different from a normal tray on which regular ones are placed is provided.

  As the dummy IC tag, a defective IC tag determined to be defective in the IC tag manufacturing process may be used. This is because a defective product has the same appearance as a non-defective product. Even if the yield (non-defective product / total number of manufactured products) is low in the manufacturing process, the defective product is used as a dummy IC tag, so that the substantial yield increases. This defective product and non-defective product are sold as a set. The purchaser embeds a plurality of defective IC tags into one non-defective IC tag in paper or a bag.

  When the number of dummy IC tags is larger than that of the regular IC tags, the probability of taking out the regular IC tags is reduced. However, this is a problem of probability, and depending on the value of the article, the number of dummy IC tags may be smaller than that of regular IC tags.

  If a defective product produced in the IC tag manufacturing process with the same assigned number is used as a dummy IC tag, there is a possibility that it may operate normally even if it is determined as a defective product. In that case, the number of the dummy IC tag and the number of the regular IC tag interfere with each other. Therefore, a defective product generated in the IC tag manufacturing process with a different allocation number is used as a dummy IC tag in the set.

  If the manufacturing yield is improved, the number of defective products cannot secure the number required for the dummy IC tag. Therefore, it is preferable to provide a dedicated assignment number for the dummy IC tag. If there is an assigned number, even if the abuser has some reading device, if the abuser does not know the number assigned to the reading target, it cannot be determined whether it is dummy or regular. However, if the abuser has a device that can only determine the appearance or shape of the IC tag, such as an X-ray, the assignment number may not be recorded in the dummy IC tag.

  In addition, if the allocation number of the dummy IC tag is the same in a wide range such as a bag, and the allocation number is different for each brand to the regular IC tag, the target article can be specified by the combination of the regular and the dummy. , Since it can only be abused in combination, abuse can be suppressed.

  It can be used in industries such as the manufacture of paper using IC tags.
