Next, the write receipt data 54 (receipt information) stored in the EJ memory 31 and the daily sales data 53 (sales information) stored in the fiscal memory 50 will be described. As described above, these data correspond to fiscal information.
The write receipt data 54 is data indicating information recorded on a receipt issued by the fiscal printer 16 and is data predetermined as data to be stored. For example, on the receipt, for each product purchased by the customer, information indicating the product, information indicating the unit price of the product, information indicating the number of the product purchased, information indicating the purchase price of each product, all products In the case where information indicating the total purchase price is recorded, and data indicating these information is predetermined as data to be stored, the data indicating these information corresponds to the write receipt data 54 .
As described above, in the present embodiment, when a receipt is issued by the fiscal printer 16, a control command is generated by the host computer 15, this control command is output to the main control unit 25, and the control command is further transmitted to the main control unit. 25 to the printer control unit 45. At that time, the main control unit 25 extracts information to be stored as the write receipt data 54 from the control command, and controls the first memory control unit 32 using the extracted information as the write receipt data 54, Store in the EJ memory 31.
In the present embodiment, the written receipt data 54 includes a subtotal amount T1, a total amount T2, and a payment amount T3 in the receipt. That is, as described above, the receipt issued by the fiscal printer 16 according to the present embodiment records the subtotal amount T1, the total amount T2, and the payment amount T3 (see FIG. 3). The unit 25 extracts at least these three pieces of information from the control command and stores them in the EJ memory 31 as write receipt data 54.

Here, when the main control unit 25 writes the write receipt data 54 in the EJ memory 31, the main control unit 25 acquires data indicating the current date and time (date + time) from the RTC 30, and indicates the date based on the acquired data. EJ writing date / time data 55 (date / time information) is generated, and writing receipt data 54 and EJ writing date / time data 55 are written in association with each other. That is, each of the write receipt data 54 is stored in the EJ memory 31 in association with the EJ write date / time data 55 which is data indicating the date / time written in the EJ memory 31.
Further, when writing the write receipt data 54, the main control unit 25 obtains a hash value from the write receipt data 54 based on a predetermined hash function, and the obtained hash value is a secret key unique to the fiscal printer 16. By encrypting, an EJ digital signature 56 (additional information) as a digital signature is generated, and the write receipt data 54 and the EJ digital signature 56 are written in association with each other. That is, each of the write receipt data 54 is stored in the EJ memory 31 in association with the EJ digital signature 56 generated based on each data. The server device 11 manages the hash function used when each fiscal printer 16 generates the EJ digital signature 56 and manages the public key corresponding to the private key of each fiscal printer 16, as will be described later. Based on the write receipt data 54 received from a certain fiscal printer 16 and the corresponding EJ digital signature 56, alteration of the write receipt data 54 can be detected.
Note that one reason for storing the EJ writing date / time data 55 and the writing receipt data 54 in association with each other is that, depending on the country, this is required by law or regulation.

The daily sales data 53 (sales information) is the total sales of “1 day” obtained by the accounting in which the receipt is issued by the fiscal printer 16. In the present embodiment, “one day” is a period from opening to closing in a store to which the store system 10 is applied. The host computer 15 controls the fiscal printer 16 for each transaction performed at the cashier counter L and issues a receipt, and cumulatively stores the sales amount (= payment amount T3 in the receipt) for each transaction. Then, after closing the store, the host computer 15 is based on the sales amount for each transaction stored cumulatively at a predetermined timing (for example, when a person in charge has instructed or at a predetermined time). The total sales for “one day” related to the corresponding fiscal printer 16 are calculated, and the daily sales data 53 is generated based on the calculated total sales. The generated daily sales data 53 is stored in the main control unit 25. Output. When the daily sales data 53 is input, the main control unit 25 controls the second memory control unit 51 to write the daily sales data 53 into the fiscal memory 50.
Here, when writing the daily sales data 53 to the fiscal memory 50, the main control unit 25 causes the RTC 30 to output data indicating the current date and time, and acquires and acquires the date and time of writing based on this data. The daily sales data 53 is written to the fiscal memory 50 in a state where the fiscal writing date / time data 52 (date / time information), which is data indicating the date / time, and the daily sales data 53 are associated with each other. That is, each of the daily sales data 53 is stored in the fiscal memory 50 in association with the fiscal writing date / time data 52 which is data indicating the date / time written in the fiscal memory 50.
Furthermore, when writing the daily sales data 53, the main control unit 25 generates a fiscal digital signature 58 (additional information) as a digital signature based on the daily sales data 53, and the daily sales data 53 and the fiscal digital data. The signature 58 is associated and written. That is, each of the daily sales data 53 is stored in the fiscal memory 50 in association with the fiscal digital signature 58 generated based on each data.
In this example, the hash function and secret key used when generating the fiscal digital signature 58 are the same as those used when generating the EJ digital signature 56, but they may be different. Good.
As described above, in the present embodiment, the fiscal writing date / time data 52 and the daily sales data 53 are stored in association with each other, but this is required by law or regulation in some countries. Because.

It should be noted that a dedicated program having a function of analyzing a mail described in conformity with a predetermined format and acquiring the type of fiscal information to be transmitted and a specific period is installed in the fiscal printer 16.
Next, the information processing unit 25 a accesses the EJ memory 31 and uses the EJ writing date / time data 55 to write the receipt data 54 related to the receipt issued on “2012/1/1” which is a specific period. And all the corresponding EJ digital signatures 56 are acquired (step SB3).
Further, the information processing unit 25a accesses the fiscal memory 50 and uses the fiscal writing date / time data 52, and the daily sales data 53 of “2012/1/1”, which is a specific period, and the corresponding fiscal data. The digital signature 58 is acquired (step SB4).
Next, the information processing unit 25a analyzes the mail to identify the telephone number to which the fiscal information is to be transmitted, establishes a connection with the telephone network 12 based on the telephone number, and then acquires the document acquired in step SB3. All of the included receipt data 54 and the corresponding EJ digital signature 56, the daily sales data 53 acquired in step SB4, and the corresponding fiscal digital signature 58 are transmitted to the server device 11 (step SB5).

As described above, in this embodiment, the GPRS communication module 34 is provided in the fiscal printer 16, and the server apparatus 11 makes a transmission request for fiscal information by mail using SMS. For this reason, it is possible to send a fiscal information transmission request from the server apparatus 11 to the fiscal printer 16 by a simple means using an existing system called mail using the telephone network 12.
Further, the above configuration provides the following effects.
That is, since mail using SMS is a push-type electronic mail, it is immediately and actively transmitted to the fiscal printer 16. For this reason, after the user of the server apparatus 11 gives a request for transmission of fiscal information, the request for transmission is immediately and forcibly notified to the fiscal printer 16, and in response to this, the fiscal information is promptly transmitted. Processing for transmission is performed, and fiscal information is transmitted. For this reason, when acquiring the fiscal information, it is possible for a person on the store side to acquire the fiscal information unexpectedly before performing any processing on the fiscal printer 16 such as illegal concealment. This makes it possible to discover fraud using fiscal information more effectively and quickly.

When the fiscal information acquisition unit 60a of the server device 11 receives the write receipt data 54 and daily sales data 53 as the fiscal information from the fiscal printer 16 (step SA3), the digital signature corresponding to these data is received. By using this, the presence / absence of tampering is detected (step SA4). As described above, since the server device 11 manages the hash function of each fiscal printer 16 and the public key corresponding to the encryption key, it can detect the presence or absence of falsification using an existing method.
Next, the fiscal information acquisition unit 60a determines whether or not tampering has been detected in step SA4 (step SA5), and if it has been detected (step SA5: YES), controls the server side display unit 63 to display The panel displays that there is a possibility that the fiscal information has been falsified (step SA6). As a result, the user of the server apparatus 11 can quickly and easily recognize that there is a possibility that the fiscal information has been tampered with.
On the other hand, when tampering is not detected in step SA4 (step SA5: NO), the fiscal information acquisition unit 60a checks the consistency between the subtotal amount T1 and the total amount T2 based on the written receipt data 54. (Step SA7).
Specifically, in one written receipt data 54, the total of the subtotal amount T1 and the total amount T2 should match unless some alteration is made. Based on this, the fiscal information acquisition unit 60a extracts the subtotal amount T1 and the total amount T2 from one written receipt data 54, compares the total of the subtotal amount T1 with the total amount T2, and matches. If it does not match, it is determined that there is consistency. The determination of the presence / absence of consistency may be performed for all the write receipt data 54 or a part thereof.
Next, the fiscal information acquisition unit 60a determines whether or not there is no consistency in step SA7 (step SA8). If it is determined that there is no consistency (step SA8: YES), the processing procedure is changed to step SA6. The server side display unit 63 is controlled to display on the display panel that the fiscal information, in particular, the write receipt data 54 may be falsified (step SA6). As a result, the user of the server apparatus 11 can quickly and easily recognize that there is a possibility that the written receipt data 54 has been tampered with. When displaying, it may be displayed in the written receipt data 54 how there is no consistency between the subtotal amount T1 and the total amount T2.

On the other hand, when it is determined that there is consistency (step SA8: NO), the fiscal information acquisition unit 60a, based on the write receipt data 54 and the daily sales data 53, and the daily receipt data 54 The consistency with the sales data 53 is inspected (step SA9).
Specifically, unless some alterations have been made, the total amount of payment T3 for all receipts issued in a certain period and the total in the accounting performed with the issuance of receipts for that particular period Sales should match. Based on this, the fiscal information acquisition unit 60a extracts the payment amount T3 from all the written receipt data 54, compares the sum of the payment amount T3 with the total sales indicated by the daily sales data 53, and matches. If it does not match, it is determined that there is consistency.
Next, the fiscal information acquisition unit 60a determines whether or not there is no consistency in step SA9 (step SA10). If it is determined that there is no consistency (step SA10: YES), the processing procedure is changed to step SA6. The server side display unit 63 is controlled, and the display panel is falsified with fiscal information, in particular, either the written receipt data 54 or the daily sales data 53, or both. It is displayed that there is a possibility (step SA6). As a result, the user of the server device 11 can quickly and easily recognize that there is a possibility of falsification. In addition, when displaying, it may be displayed how there is no consistency.

On the other hand, if it is determined that there is consistency (step SA10: NO), the fiscal information acquisition unit 60a controls the server side display unit 63 to display on the display panel that no alteration to the fiscal information has been detected. (Step SA6).
As described above, in the present embodiment, the fiscal information acquisition unit 60a uses the characteristics of the information recorded in the received write receipt data 54 and the daily sales data 53 to check whether or not tampering has occurred in many ways. Try to detect. For this reason, it is possible to detect tampering more reliably, and this is a stronger deterrence against tampering.

Here, the fiscal printer 16 according to the present embodiment has a novel configuration called a GPRS communication module 34, and the module transmits fiscal information to the server device 11, but the power of the power source provided in the fiscal printer 16 is not limited. Depending on the performance (output voltage), when a series of processing related to receipt issuance and fiscal information transmission are performed in parallel, a voltage may not be secured for performing a series of processing related to receipt issuance. obtain. For the fiscal printer 16, issuance of a receipt is one of the main purposes, and such a situation must be avoided. In general, when data is transmitted via the telephone network 12, since processing such as establishment of a connection with the telephone network 12 is performed, the power consumption is large, and therefore a receipt by transmitting the fiscal information more reliably. It is necessary to suppress the influence on the operation related to the issue of
Based on the above, the fiscal printer 16 according to the present embodiment performs the following processing.

FIG. 7A is a flowchart showing the operation of the fiscal printer 16 when the power is turned on.
When the power is turned on, the information processing unit 25a of the main control unit 25 of the fiscal printer 16 determines whether or not the power source provided in the fiscal printer 16 has high performance (step SC1). Here, a high-performance power supply means an output that can secure a power supply voltage for any process even when a series of processes related to issuance of receipts and transmission of fiscal information are performed in parallel. It has a power supply. The determination in step SC1 is performed as follows, for example. That is, the management board 20 is equipped with a dip switch that is intended to be switched depending on whether the power source is high-performance, and the dip switch is appropriately switched in advance depending on whether the power source is high-performance. It has been. When the power is turned on, the information processing unit 25a detects an input to a predetermined port of the CPU from the DIP switch, and determines whether or not the power source has high performance based on the input. Note that any discrimination method may be used in step SC1, and all existing discrimination methods can be applied.
Next, when the information processing unit 25a determines that the power source has high performance (step SC1: YES), the information processing unit 25a shifts the operation mode to the second mode (step SC2). The second mode is a mode in which fiscal information is appropriately transmitted in response to a transmission request from the server device 11 without being influenced by whether or not a receipt is issued.
On the other hand, when it is determined that the power source is not high-performance (step SC1: NO), the information processing unit 25a shifts the operation mode to the first mode (step SC3). The operation mode B will be described later.

FIG. 7B is a flowchart showing the operation of the fiscal printer 16 in the first mode.
When the operation mode is the first mode, the information processing unit 25a of the fiscal printer 16 receives a control command related to issuance of a receipt from the host computer 15 and monitors whether or not to start issuance of a receipt (step) SD1). When issuing a receipt (step SD1: YES), the information processing unit 25a stops the operation of the GPRS communication module 34 (step SD2). The stop of the operation is performed by hardware and / or software means such as limiting the supply of power to the GPRS communication module 34, for example.
Next, the information processing unit 25a monitors whether or not a series of processing relating to the receipt issuance is completed (step SD3). When completed (step SD3: YES), the information processing section 25a cancels the stop of the operation of the GPRS communication module 34 (step SD4).
As described above, in the first mode, the information processing unit 25a stops the operation of the GPRS communication module 34 during the receipt issuance, and accordingly, the fiscal information is transmitted in parallel with the receipt issuance. Ban. Thereby, the GPRS communication module 34 is newly provided in the fiscal printer 16, and adverse effects caused by transmitting the fiscal information to the server apparatus 11 through communication can be reliably and accurately eliminated.
