DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lottery system in which a point card and a prize lottery ticket used in a shopping street or the like are realized by one portable recording medium.

[0002]

2. Description of the Related Art In a prize lottery during a sale in a shopping district, a lottery ticket (paper) is obtained for each purchase of a fixed amount, and a lottery is performed at a prize exchange. ing. However, in this method, a lottery ticket is hard to accumulate on the shopper side because the lottery ticket is delivered for each shopping. For example, in the case of a small purchase, a lottery ticket cannot be obtained because it is less than one lottery ticket. Since it is troublesome, lottery tickets will not be accumulated during the lottery period. If the sale period has passed, the lottery ticket will be invalidated. On the other hand, the store that issues the lottery ticket needs to make preparations for issuing the lottery ticket and the like, and has to perform a troublesome operation.

[0003] The present invention is intended to solve the above-mentioned problems, and it is possible for a shopper to reliably secure the right of a lottery when shopping during a sale period, and for a shop side to prepare for the issuance of a lottery ticket. It is an object of the present invention to provide a system that can contribute to the revitalization of shopping streets.

[0004]

SUMMARY OF THE INVENTION The present invention is a system that uses a random number generation function of a portable recording medium such as an IC card to draw a winning number for a prize. This is realized by electronic information stored in a single portable recording medium. Furthermore, a lottery is executed by using the random number generation function of the portable recording medium, so that even when the lottery period has elapsed, the right can be carried over. That is, the shopping points corresponding to the shopping price are stored in a portable recording medium together with time information such as the shopping date and time as calculation data of the number of lottery rights, and when the integrated value of the shopping points reaches a predetermined value, one lottery right is determined. generate. In addition, points within the sale period and points outside the period can be distinguished, and even points outside the period can contribute to the generation of lottery rights at a predetermined rate.

[0005]

Embodiments of the present invention will be described below. In the following, the portable recording medium is I
As long as it has a random number generation function, a memory function, and a calculation function like a C card, it is not limited to an IC card, and any portable recording medium can be applied.

Next, the system configuration of the present invention will be described. In FIG. 1, when a portable recording medium 2 such as an IC card is set in a reader / writer 1 and a PIN (Personal Identification Number) is confirmed,
A command (command) is transmitted from the reader / writer 1 to the portable recording medium 2, and the portable recording medium 2 receives the command.
Interprets the command, executes processing such as writing, reading, and reading, and returns the processing result as a response to the reader /
Return to writer 1. Of course, input of the PIN is not essential, and may be omitted.

[0007] As shown in FIG.
It has a PU 20, a RAM 21, a ROM 22, and a rewritable nonvolatile memory 23. The ROM 22 stores various programs including a program for generating a random number for use in the lottery process. Of course, the generation of the random numbers may be constituted by a random number generation circuit and a program for activating the circuit. When the CPU 20 reads the program stored in the ROM 22 and receives a command transmitted from the reader / writer 1 through the I / O port,
The data transmitted together with the command is read, necessary processing is performed, the result is written in a predetermined file area of the EEPROM 23, and a response is output through the I / O port.

The reader / writer 1 is a host computer 3
The lottery process is performed by activating a lottery process program of the host computer 3. It should be noted that the host computer (personal computer) may be configured to also serve as a reader / writer.

Next, shopping points for obtaining lottery rights will be described with reference to FIG. After receiving a shopping or service at a shopping street, when a point card is presented, points corresponding to the payment amount are accumulated in the portable recording medium. In this accumulation, as shown in the figure, points acquired for each shopping item and time information such as the date and time at that time are stored in association with each other. When this point reaches a predetermined value, for example, 5 points, a right for one lottery is obtained. In that case, the conversion rate to the lottery ticket can be set within the sale period and outside the period, and even the shopping points after the period can contribute to the lottery. For example, a single lottery can be performed with five points for shopping during the period, and one lottery with ten points for shopping outside the period.

In the lottery process, when the portable recording medium 2 is set on the reader / writer 2 and the lottery process is started, the host computer 3 determines whether or not there is a shopping point for one lottery and whether the lottery is performed. Ask for something. If there is a shopping point for one lottery, a random number is requested to the portable recording medium 2. And reader / writer 1
When the random number is received through the, the winning number and the random number are compared, and the hit / miss is determined, and the result is displayed or printed out.

Next, a lottery process flow when an IC card is used as a portable recording medium will be described with reference to FIG. In the lottery process, it is determined whether or not an IC card has been inserted (S1), and if inserted, it is determined whether or not there is a point for one lottery (S2). In this case, points are accumulated, and the number of lotteries is calculated on the IC card side. If there is more than one point, it is determined whether or not to perform a lottery (S3). If there is an intention to perform the lottery, the points for one lottery are subtracted and recorded on the IC card (S4). Next, the host computer requests the IC card to generate a random number (S5), compares the winning numbers (S6),
Missing hit processing is performed (S7). In the hit processing,
The winning number can be compared with the last three digits of the random number, or a specific prize can be given depending on whether the last three digits of the random number are even or odd. After S7, the process returns to S2, and the same processing is repeated. When there is no point for one lottery, or when there is no intention to perform a lottery, the IC card is ejected, and the process ends (S8).

FIG. 5 is a diagram for explaining a process of determining whether or not there is a lottery right. In the IC card, shopping points and time information are recorded in association with each other for shopping. First, the point addition value is initialized (S11), and the time information is referred to (S12). It is determined whether it is within (S13). Next, for example, if shopping within the period is given one lottery right at 5 points and shopping outside the period is given one lottery right at 10 points, the points are multiplied by 1 during the sale period ( S1
4) If the sale period has passed, the point will be 0.
5 (S15), and these values are added (S1).
6). Next, it is determined whether or not processing has been performed for all the logs (histories) of shopping (S17). If the processing has not been completed for all the logs, the process returns to S11 and the same processing is repeated. If all of them have been completed, it is determined whether the added value is 5 or more. If it is 5 or more, there is a lottery right, and if less than 5, there is no lottery right.

[0013]

As described above, according to the present invention, the daily shopping points become the right of the lottery, so that the shopping street can be activated and the store side does not need to prepare for issuing the lottery ticket. Can be. In addition, since it is done with an IC card, it can be done via a network even if it is not a lottery place, it can also be used as daily shopping points, so points can be accumulated even after the sale period ends, and after the sale period But it can be used effectively. Further, conventionally, at the time of shopping, data had to be recorded online on a server or the like. However, according to the present invention, the date and time of shopping recorded on the IC card can be counted offline instead of at the time of shopping. Can be. In addition, since people who apply for the lottery repeatedly can be determined to have high loyalty, they can also be used offline for data analysis.
