Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a crime prevention system that uses, for example, unique identification information recorded on a non-contact IC tag attached to a product, and in particular, prevents malfunction when a product sold externally is brought in and the product is left behind. It relates to effective technology applied to management.
[0002]
[Prior art]
In recent years, non-contact IC tags that have a much larger storage capacity than conventional bar code tags and can read registered information in a non-contact manner and products using the same have become widespread. Since this non-contact IC tag uses electromagnetic waves to read contents from a distance, it is increasingly used for crime prevention and product management.
[0003]
The technology for reading the data registered in the non-contact IC tag and the technology for writing the data have been put to practical use as a non-contact IC reader / writer. Some products can detect a plurality of types of goods when passing through (see, for example, Patent Document 1).
[0004]
In addition, the operation of pasting product management tags and security tags on products during manufacture by a manufacturer called source tagging has been put into practical use, and the operation of using contactless IC tags as product management tags and security tags has also been put into practical use. .
[0005]
In a crime prevention system that uses a non-contact IC tag attached to a product by source tagging for crime prevention, when the product is purchased, a piece of identification information of the non-contact IC tag attached to the product by a non-contact IC tag writer. Purchased processing is performed such as changing part or all or writing information about the purchase.
[0006]
Then, when moving from a specific place, it is determined whether the purchase has been processed by reading the non-contact IC tag attached to the product by source tagging with a non-contact IC tag reader. Execute alarm processing.
[0007]
Further, in a crime prevention system that uses a non-contact IC tag attached to such a product for crime prevention, an alarm process can be performed depending on whether or not the purchase has been completed in the store where the product is sold. However, when a non-contact IC tag is attached to a product sold at another store and brought in from the outside, the alarm operation may malfunction because the processing of the non-contact IC tag at the other store is unknown. .
[0008]
Therefore, conventionally, there has been a technique in which the non-contact IC tag itself cannot be detected in order to prevent malfunction caused by a product purchased at another store (see, for example, Patent Document 2).

[Problems to be solved by the invention]
By the way, as a result of examination of the alarm operation technique in the above-described crime prevention system, the following has been clarified.
[0012]
In operation where non-contact IC tags are pasted to products by source tagging, past non-contact IC tags are not removed after the products are sold. Therefore, products sold through other distribution channels are not contacted IC tags. May be brought into the store with the sticking.
[0013]
In this case, there is a possibility that the purchased process of the non-contact IC tag attached to this product is not correctly performed. If the non-contact IC tag has not been purchased, the non-contact IC tag identification information There was a problem that a false alarm might be issued.
[0014]
For this reason, conventionally, as described in Patent Document 2, some non-contact IC tags themselves are prevented from being detected, thereby preventing malfunctions. However, there is a possibility that the technology may be used for theft. .
[0015]
Conventionally, since the product brought in from the outside is not managed, there is a problem that even if the product brought into the store is left behind, the product cannot be confirmed.
[0016]
The present invention has been made in order to solve such a problem, and malfunction of an alarm operation caused by a brought-in product regardless of a processing state of a non-contact IC tag of a product sold from another distribution channel.

[0031]
The product management database 123 stores non-contact IC tag identification information. Based on the non-contact IC tag identification information stored in the product management database 123, an alarm process or the like is performed. The alarm device 124 performs an alarm process when the merchandise management server 12 detects a stolen product.
[0032]
Next, referring to FIG. 2, a process when bringing a commodity in the crime prevention system in the present embodiment will be described. FIG. 2 is a flowchart showing processing of identification information when a product is brought in from the outside.
[0033]
First, when the product 11 passes from the outside through the gate-type non-contact IC reader 122 and is brought in, the gate-type non-contact IC reader 122 obtains the unique identification information of the non-contact IC tag 111 of the brought-in product 11. Read (S100), and the non-contact IC tag identification information read in S100 is registered in the product management database 123 (S101).
[0034]
Then, it is determined whether or not the business has ended (S102). If it is determined in S102 that the business has not ended, the process returns to S100, and the processing is repeated until it is determined in S102 that the business has ended.
[0035]
By this processing, all the unique identification information of the non-contact IC tag 111 attached to the brought-in product 11 through the gate-type non-contact IC reader 122 from the outside is registered in the product management database 123.
[0036]
Next, referring to FIG. 3, the processing at the time of product purchase of the security system in the present embodiment will be described. FIG. 3 is a flowchart showing processing of identification information when a product is purchased.
[0037]
First, when the product 11 is purchased, the contactless IC reader / writer 121 reads the unique identification information of the contactless IC tag 111 of the purchased product 11 (S110), and the contactless IC tag identification read in S110. Information is registered in the product management database 123 (S111).
[0038]
Then, the non-contact IC reader / writer 121 writes information such as purchased information to the non-contact IC tag 111 of the purchased product 11 (S112), determines whether or not the business has ended (S113), and the business in S113. If it is determined that the processing is not ended, the process returns to S110, and the processing is repeated until it is determined that the business is ended in S113.
[0039]
Through this processing, all the unique identification information of the non-contact IC tag 111 attached to the purchased product 11 is registered in the product management database 123.
[0040]
Next, the process at the time of taking out the goods of the security system in this Embodiment is demonstrated with reference to FIG. FIG. 4 is a flowchart showing a process when a product is taken out.
[0041]
First, when the product 11 passes through the gate-type non-contact IC reader 122 and is taken out, the gate-type non-contact IC reader 122 obtains the unique identification information of the non-contact IC tag 111 of the taken-out product 11. Read (S120).
[0042]
Then, the identification information registered in the merchandise management database 123 is read in one case (S121), compared with the identification information read in S120, and it is determined whether or not the corresponding information exists (S122). If it is determined that all of the identification information registered in the merchandise management database 123 has been confirmed (S123). If it is determined in S123 that all of the identification information has not been confirmed, S121 is determined. Returning to step S121, the processes in S121 to S123 are repeated until all of the identification information registered in the product management database 123 is confirmed.
[0043]
When it is determined in S122 that the corresponding information is registered in the product management database 123, it is determined that the product 11 with the identification number is a take-out permitted product, and the identification number of the corresponding product is deleted from the product management database 123. Then, it is determined whether or not the business has ended (S126). If it is determined in S126 that the business has not ended, the process returns to S120, and the processes in S120 to S126 are repeated until it is determined in S126 that the business has ended.
[0044]
If it is determined in S123 that all of the identification information registered in the product management database 123 has been confirmed, it is determined that a product not registered in the product management database 123 has been taken out, and an alarm is issued from the alarm device 124. (S124), it is determined whether or not the job is completed (S126). If it is determined in S126 that the job is not completed, the process returns to S120, and until it is determined in S126 that the job is completed, S120 is performed. The process of S126 is repeated.
[0045]
With this process, when the product 11 is taken out, and the product 11 whose identification number is registered in the product management database 123 is taken out, information on the corresponding identification number is taken out from the product management database 123 as a take-out permitted product. When a product 11 that has been deleted and whose identification number is not registered in the product management database 123 is taken out, it is determined that the product is a stolen product, an alarm operation is performed, and the non-contact IC tag 111 of the product 11 brought in from the outside is detected. Regardless of the processing state such as sales information, only the stolen product is alerted.
[0046]
Next, with reference to FIG. 5, the product leaving process at the end of the operation of the security system in the present embodiment will be described. FIG. 5 is a flowchart showing a process for confirming whether there is a product left behind after the end of business.
[0047]
First, after the work is completed, one piece of identification information registered in the product management database 123 is read (S130), and it is determined whether there is any identification information of the remaining products registered in the product management database 123 (S131). ).
[0048]
If it is determined in S131 that there is the identification information of the remaining product registered in the product management database 123, it has been brought in and left without being taken out, or has been purchased and taken out as it is. As a product that has been left without being displayed, information that can collect the product that has been left is displayed, or processing such as provision to other systems is performed to carry out the product leaving process (S132), The processing of S130 to S132 is repeated until it is determined in S131 that there is no identification information of the remaining product registered in the product management database 123.
[0049]
As a result of this processing, it is assumed that the product 11 with the identification number that is still registered in the product management database 123 at the end of the business is brought into the store after being brought in or sold. Product leaving processing is performed.
[0050]
In this embodiment, when the product 11 is sold, the contactless IC reader / writer 121 writes information such as sales information on the contactless IC tag 111 of the sold product 11. In the case where management is possible simply by registering identification information in the management database 123, information such as sales information may not be written in the non-contact IC tag 111.
[0051]
Further, the present invention can be applied even if the non-contact IC tag 111 attached to the product 11 is a read-only and non-contact IC tag to which information such as sales information cannot be written.
[0052]
In this embodiment, when the product 11 is purchased, the non-contact IC reader / writer 121 reads the unique identification information of the non-contact IC tag 111 of the purchased product 11, When a product is purchased, for example, when sales processing is performed in another sales management system such as a POP system, the contact information of the contactless IC tag 111 of the purchased product 11 is obtained from the sales information of the system. You may make it acquire unique identification information.
[0053]
【The invention's effect】
As described above, according to the present invention, when a product is brought in from the outside, the non-contact IC reader reads the product-specific identification information recorded on the non-contact IC tag of the product brought in from the outside, and identifies the product. When the information is registered in the database and the product is taken out to the outside, the non-contact IC reader reads the product-specific identification information recorded in the non-contact IC tag of the product to be taken out to the outside. When not registered in the database, an alarm operation is performed. Therefore, even if the product purchase identification information of the non-contact IC tag brought in from the outside is not processed normally, the alarm operation is performed without malfunction. Can be done.
[0054]
Also, when a product is purchased, the product-specific identification information registered in the contactless IC tag of the purchased product is acquired and the identification information is registered in the database. It becomes possible to carry out the same processing as that of the goods brought in at the time.
[0055]
Also, when a product is taken outside, the product-specific identification information recorded on the non-contact IC tag of the product taken outside is deleted from the database, and the identification registered in the database at the end of business Since the information is displayed or provided to other systems as identification information of the goods brought in or purchased and left behind, it is easy to grasp the goods left behind. It becomes possible.
