2. Description of the Related Art At present, there is an increasing need to identify a person in various situations. For example, in a retail store, there is a demand for promptly knowing whether or not the customer currently visiting the store is a customer, and if the customer is, what kind of name and consumption trend the customer has. There is. If the salesclerk contacts the customer after grasping such data, the customer can be properly serviced.

As a result, it is possible to expect an increase in sales and also to improve the customer's impression of the store. In addition to the customer management of retail stores as described above, promptly determine whether the person who is going through the entrance or reception is an employee of the company or an outside person at the company etc. There is a demand to identify.

Conventionally, in order to identify such a person, a member's card such as a magnetic card or a memory card, an identification card, etc. have been distributed in advance to a specific person such as a customer or an employee. When a retail store or the like needs to identify a customer or the like, they are required to present these cards, and further, these cards are read by a reading device to read the contents of the cards.

[0005]

However, it is troublesome for a cardholder such as a customer to present a card or put it on a reading device each time. For this reason, it is difficult to ask the card owner to present the card, etc., unless the card owner feels the need or the cardholder can expect some benefit from using the card. .

On the other hand, the person who wants to manage may want to know the contents of the card even if there is no particular merit to the owner. For example, if the customer can be identified at the time of coming to the store as described above, it is possible to provide detailed service to the customer. However, it is troublesome for the customer to present the card just after visiting the store.

According to the present invention, even if the owner of the card does not present the card or put it on the reading device, the owner only carries the card and carries it.
It is an object of the present invention to provide a system capable of transmitting / receiving the contents of a card as an encrypted signal and knowing the contents.
The present invention further provides:
By performing information processing such as calling the card owner's data from the data accumulated in the past and displaying it, a system that can provide a detailed service based on the data to the card owner It is intended to be provided.

[0008]

In order to achieve the above-mentioned object, the present invention is a portable device which is owned by a specific person and activates itself by receiving a signal from the outside, thereby transmitting a preset cipher. The mold transmitter is incorporated into a card or the like. Then, this card or the like is distributed in advance to a specific person such as a customer. In addition, a transmitting device that transmits a signal for activating the portable transmitting device and a receiving device that receives the signal from the portable transmitting device and demodulates and reproduces the cipher are provided at a predetermined location such as an entrance of a store or a company. Installed at a location to configure a wireless encryption transmission / reception system.

Further, according to the present invention, an information processing device is connected to the output side of the receiving device of the wireless cipher transmitting / receiving system. Then, this information processing device performs information processing such as selecting the data already collected based on the information obtained from the receiving device and displaying the content of the selected data on a display or the like. This constitutes a management system for identifying and managing the person who owns the portable transmission device.

[0010]

According to the above means, when the owner of the portable transmitter incorporated in a card or the like tries to enter the store or company, the portable transmitter can pass near the place where the transmitter and the receiver of the wireless cipher transmission / reception system are installed. Becomes At this time, the portable transmission device is activated by receiving a signal from the transmission device and transmits a preset cipher to the outside. This cipher is received by the receiving device, demodulated and reproduced, and data relating to the cardholder is displayed on an appropriate display according to the contents of the cipher.

In this way, the management side can read the contents of the card or the like simply by the customer or employee trying to enter the store or company while wearing the card or the like.
Therefore, the management side can obtain the necessary data without burdening the customer or the like. Further, an information processing device may be further connected to the output side of the receiving device, and the data accumulated in the past can be selected and read according to the contents of the demodulated and reproduced cipher, and this can be displayed. As a result, various data such as past consumption trends can be known on the spot regarding customers who have visited the store.

(Embodiment 1) A specific example of the wireless cipher transmission / reception system of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the entire system. A human body detection sensor 1, a trigger signal transmission device 2, an encryption signal reception device 3, and a display device 4 are installed at the entrance of a store, a company, or the like. The human body detection sensor 1 is composed of an infrared sensor. When the human body approaches, the human body detection sensor 1 detects infrared rays emitted by the human body and outputs an output. With this output, the trigger signal transmitting device 2 and the cipher signal receiving device 3 start operating. It should be noted that the human body detection sensor 1 can also obtain a signal from an automatic door instead of the infrared sensor.

The trigger signal transmitting device 2 generates a predetermined frequency when activated by the output of the human body detecting sensor 1. The generated signal of a predetermined frequency is radiated to the outside from the transmitting antenna 5 as a trigger signal. The output of the human body detection sensor 1 is also input to the cryptographic signal reception device 3 to activate it. When the cipher signal receiving device 3 is activated, the cipher signal receiving device 3 enters a state in which it can receive the cipher transmitted from the cipher transmitting device described later.

When the cryptographic signal receiving device 3 receives the cryptographic signal, the display device 4 displays that the cryptographic signal has been received. If further necessary, the specific person code which is the content of the encryption is displayed. Reference numeral 6 denotes a member's card 7 distributed to a customer or an employee in advance or an encryption transmission device incorporated in an identification card. This card 7
Etc. are carried when a customer visits a retail store or when an employee is about to enter the company.

The details of the cipher transmission device 6 are shown in FIG.
The cipher transmission device 6 includes a reception antenna 8, a trigger signal detection unit 11, a trigger signal generation unit 12, and an oscillation circuit control unit 1.
3, an oscillator circuit 14, a transmission antenna 15, and a power supply circuit 16. Of these, the oscillation circuit control unit 13 and the oscillation circuit 14 are operated by being supplied with power from the power supply circuit 16, but in a normal state, the power supply from the power supply circuit 16 to these circuits 13 and 14 is cut off. There is.

Next, the operation of the system configured as above will be described. In a normal state, since the output of the human body detection sensor 1 is not input to the trigger signal transmission device 2 and the cipher signal reception device 3, both of them do not operate. On the other hand, when a person approaches the entrance of a store, a company, etc. where the system is installed, the human body detection sensor 1 detects the human body and outputs a detection signal to the trigger signal transmission device 2 and the encryption signal reception device 3. To do.

The trigger signal transmission device 2 starts its operation by the output of the human body detection sensor 1, and transmits a radio wave of a specific frequency from the transmission antenna 5 as a trigger signal. Here, when the approaching person owns the cryptographic transmission device 6 incorporated in the card 7, the reception antenna 8 of the cryptographic transmission device 6 catches the radio wave emitted by the trigger signal transmission device 2. When the trigger signal detector 11 detects this trigger signal, the trigger signal generator 12 generates a trigger signal for the oscillation circuit controller 13.

When this trigger signal is supplied to the oscillation circuit control unit 13, the oscillation circuit control unit 13 connects the power supply circuit 14 to the oscillation circuit control unit 13 and the oscillation circuit 14, and supplies power to these circuits 13 and 14. Is supplied. As a result, the cryptographic transmission device 6 is activated and starts operating. in this way,
Normally, the power supply circuit 16 is disconnected and connected when necessary, so as to minimize the consumption of the internal battery of the power supply.

The oscillator circuit controller 13 controls the oscillation of the oscillator circuit 14 to generate a preset encrypted signal, that is, a specific person code, and transmits it from the transmitting antenna 15. This cryptographic signal may be generated only for a certain period after receiving the trigger signal, or may continue to be generated during the period during which the trigger signal is received. The cipher signal transmitted from the cipher transmitted by the cipher transmitter 6 is picked up by the receiving antenna 16 of the cipher signal receiver 3. The cipher signal reception device 3 receives this cipher signal and demodulates and reproduces the cipher.

In this way, when the encrypted signal receiving device 3 demodulates and reproduces the encrypted signal, the display device 4 displays that the encrypted signal has been received. Further, if necessary, the content of the received cipher can be displayed on the display device 4. Accordingly, the salesclerk of the retail store or the receptionist of the company monitors the display device 4 to determine whether or not the person passing near the place where the system is installed is the customer or the employee. It is possible to easily determine whether the person is an external person.

FIG. 3 is a block diagram showing the entire system of this example. In the figure, components having the same functions as those of the first embodiment are designated by the same reference numerals, and duplicated description will be omitted. This example differs from the first example in that an information processing device 21, a data memory 22, and a display device 23 are provided on the output side of the encrypted signal receiving device 3.

Also in this example, the cipher transmission device 6 shown in FIG. 2 is used, and the cipher signal unique to the owner is demodulated and reproduced by the cipher signal reception device 3. Based on the content of the demodulated and reproduced encrypted signal, that is, the customer code, the information processing device 21 selects and reads the data corresponding to the encrypted signal from the customer data stored in the data memory 22 in the past. The read data is displayed on the display device 23.

According to this embodiment, when the customer enters the store, the display device 23 displays various data such as the name of the customer and data of shopping performed by the customer in the past. Therefore, the store clerk can deal with the customer by taking this data into consideration. As described above, understanding the past data of the customer to deal with the customer can recommend an appropriate product to the customer, promote sales, and improve credit of the store.
