Description

The present invention relates to a payment terminal and program, and more particularly to a payment terminal and program for making payments with a payment terminal wirelessly interlocked with a host terminal.

Conventionally, there is a payment terminal that is driven by a battery and performs processing related to payment. With a battery-powered payment terminal, if the power is cut off while processing related to payment is being performed, problems may arise, such as failure to make payments smoothly. For this reason, conventionally, a battery-powered payment terminal displays the remaining battery charge in order to prevent the terminal from being used to a charging level at which a series of transactions related to payment cannot be completed. In payment terminals, a mechanism is also being considered to prevent power outages during payment by changing the range in which processing can be performed according to the remaining battery power.

For example, there is a technology that reliably prohibits specific information processing when the remaining battery power of the battery drops to a warning level, thereby preventing problems from occurring in specific information processing due to power interruptions (Patent Document 2). 1).

However, even if it is possible to avoid power outages during payment by changing the executable range of processing in the payment terminal as in the above-mentioned conventional technology, it is ultimately necessary to charge the battery at an appropriate timing. be. In order to notify the timing of charging, there is also a mechanism to issue a warning to prompt charging when the remaining battery level is low.

However, even if a warning prompting the user to charge the battery or displaying the remaining battery charge is displayed, the operator of the payment terminal has the mentality that "it may still be usable", and even if the warning is displayed, the user will not use the terminal without recharging the battery. If the battery is continuously used, the battery may end up being used up to a charging level at which a series of transactions related to payment cannot be completed. In addition, it is conceivable that the user forgets to charge the battery during a busy period of work and, without being able to charge the battery at an appropriate timing, ends up using the battery to a charging level at which a series of transactions relating to payment cannot be completed.

The present invention has been made to solve the above problems, and provides a payment terminal capable of visualizing the number of remaining payments that can be made to prompt charging at an appropriate timing and suppressing interruption of payment due to a power outage; The purpose is to provide a program.

In order to achieve the above object, a payment terminal according to the present invention is a payment terminal that is driven by a rechargeable battery and performs processing related to payment of money, wherein the remaining battery capacity of the battery is used to perform the processing.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, an outline of an embodiment of the present invention will be described.

In the embodiment of the present invention, it is possible to make the remaining payments at the payment terminal, such as "At least, payment processing may be performed up to a certain number of times, but it is recommended to charge the battery after performing the payment for the predetermined number of times". We propose to visualize the number of times. Visualizing the remaining number of payments that can be made and issuing instructions to charge the battery would prevent the above-mentioned problem of using the battery to a level where the series of transactions related to payment cannot be completed. In addition, even if the number of possible payments that allow payment processing in the charging instruction is not strictly accurate, it is possible to issue an instruction of the possible number of payments at least with a remaining battery level that does not turn off the power during payment processing. We do not believe that major problems such as the loss of payment processing information due to power outages will occur.

In the embodiment of the present invention, there is a table that defines the remaining possible number of payments for a combination of reference values for each condition of the following battery conditions, and when a predetermined battery condition that matches the table is reached, the possible number of payments can be made. and prompts the charging process. In the embodiment of the present invention, a table is provided for the last five remaining possible settlement times.

・Battery temperature ・Battery charging history (number of charging times)
・Remaining battery power of the battery

For example, an announcement such as "X more times" is displayed according to the reference value of the battery status corresponding to the table. Also, when the remaining battery level falls below the reference value corresponding to the table, prompt charging is urged and control is performed so that operations such as payment processing cannot be performed. The number of charging times is the number of times the battery has been charged since the battery was first used. In addition, the reference value for the number of times the battery has been charged and the reference value for the remaining battery capacity for the final five times of payment in accordance with the reference value for the temperature of the battery are determined in advance through experiments, etc. and

Although not shown, the settlement unit 46 is configured so that it can be removed and used as necessary, and confidential information such as acquired card information can be encrypted and transmitted/received. In the settlement terminal 14, a series of transactions related to settlement consumes a large amount of power, so there arises a need to monitor the battery status using the method according to the embodiment of the present invention.

Next, a detailed configuration of the battery monitoring unit 36 will be described. As shown in FIG. 5, the battery monitoring unit 36 includes a charging circuit 36A, a remaining battery level monitoring circuit 36B, and a thermistor 36C. The charging circuit 36A controls charging of the battery 30 from the power supply unit 28.

FIG. Also, the remaining capacity monitoring circuit 36B detects the temperature of the battery 30 measured by the thermistor 36C. Also, the remaining battery capacity of the battery 30 is measured from the voltage of the battery 30 . The remaining amount monitoring circuit 36B also refers to a battery table, which will be described later, to monitor the battery status for settlement-related processing. Thermistor 36C is a detector for measuring the temperature of battery 30 .

Next, the configuration of the storage unit 34 will be described. As shown in FIG. 6, the storage unit 34 includes a charging frequency storage unit 34A, a battery table storage unit 34B, and a data storage unit 34C. The charging times storage unit 34A stores the charging times of the battery 30 recorded by the charging circuit 36A. A battery table for monitoring the remaining battery level is stored in the battery table storage unit 34B. The data storage unit 34C stores various data related to payment.

FIG. 7 shows the battery table stored in the battery table storage section 34B. The battery table stores a reference value for battery temperature, a reference value for the number of times of charging, and a remaining number of possible payments with respect to the reference value for remaining battery power. For example, the reference value for the temperature includes when it is 10°C or higher and when it is lower than 10°C. The reference values for the number of times of charging include 1 to 199 times, 200 to 399 times, 400 to 599 times, 600 to 799 times, and over 800 times. In addition, as the reference value of the remaining battery level, the reference value of the remaining battery level corresponding to the remaining number of possible settlements is determined in the range of B1 to B5 with respect to the combination of the reference value of the temperature and the reference value of the number of times of charging. ing. B5 corresponds to the remaining number of possible settlements of 5 times, and B1 corresponds to the remaining possible number of settlements of 1 time. For example, for the reference value B5 of the remaining battery capacity, when the temperature is 10° C. or higher, the number of charging times is 15% for 1 to 199 times, 20% for 200 to 399 times, 25% for 400 to 599 times, and 600 to 799 times. It is set at 30% for times and 35% for over 800 times. Further, the range of the reference values B1 to B5 of the remaining battery level is defined by 2% intervals, with the battery consumption amount per one payment being 2%. By referring to each of these reference values in the battery table, it is possible to determine the remaining number of possible payments for the battery status.

The battery monitoring unit 36 refers to each reference value of the battery table for the measured temperature of the battery 30, the recorded number of charging times of the battery 30, and the measured remaining battery capacity of the battery 30, and determines the number of remaining possible payments. . If the remaining battery level is B5 or more, it is determined that the battery is charged to the extent that the number of remaining payments that can be made is not displayed. If the remaining battery level corresponds to B5 to B1, the display unit 24 displays how many more payments can be made. For example, if the remaining number of possible payments is 5, as shown in FIG. do. Also, if the remaining battery level is less than B1, as shown in FIG. In addition, the display prompting the number of payments and charging is displayed based on the determined information when the battery monitoring unit 36 determines the remaining number of payments that can be made. Alternatively, until the battery monitoring unit 36 determines the remaining number of payments that can be made next time, a display capable of suggesting the content of the determined information may be continued at some display location on the display unit 24 of the payment terminal.
For example, the battery monitoring unit 36 determines that the remaining number of possible payments is 5, and a display such as that shown in FIG. 8A is displayed in the center of the screen. After that, when the screen display is changed for payment processing, etc., continue to display a small red letter "5 more times!" may be allowed, etc. By doing so, it is possible to further promote the visualization of the remaining number of possible payments at the payment terminal 14 . Note that the remaining battery capacity defined in B1 is an example of a threshold.

Next, an example of remaining battery level monitoring using the battery table shown in FIG. 7 will be described. As to which of the reference values B5 to B1 of the remaining battery capacity b corresponds to, Bn=B5 to B2 is specified as Bn when b is in the range of Bn≧b>Bn−1. . When Bn=B1, B1=b is specified as B1, and when Bn is less than B1, quick charging is required.

For example, when the temperature of the battery 30 is 12° C., the battery table for (1) 10° C. or higher is used. In table (1), for example, if the number of times the battery 30 has been charged is 150 times and the remaining battery capacity b of the battery 30 is 14%, the number of charging times is 1 to 199 and the remaining battery capacity b is B5≧b. >B4, and the remaining number of possible payments is specified as 5. Further, when the number of charging times of the battery 30 is 500 and the remaining battery capacity b of the battery 30 is 21%, the remaining battery capacity b satisfies B3≧b>B2 when the number of charging times is 400 to 599. The possible number of settlements is specified as 3. Further, when the number of times the battery 30 has been charged is 850 times and the remaining battery level b of the battery 30 is 27%, the number of times of charging exceeds 800 times, the remaining battery level b corresponds to B1=b, and the remaining number of settlements possible. is specified as 1. Further, when the number of charging times is 500 and the remaining battery capacity b is 30%, it is determined that the remaining battery capacity is sufficient because it is greater than B5 in the battery table. Also, when the number of charging times is 500 and the remaining battery capacity b is 13%, since B1 is less than 17%, it is determined that immediate charging is required.

When the temperature of the battery 30 is 8° C., the battery table for (2) less than 10° C. is used. In table (2), for example, if the number of times the battery 30 has been charged is 150 times and the remaining battery capacity b of the battery 30 is 19%, the number of charging times is 1 to 199 and the remaining battery capacity b is B5≧b. >B4, and the remaining number of possible payments is specified as 5. Further, when the number of charging times of the battery 30 is 500 and the remaining battery capacity b of the battery 30 is 26%, the remaining battery capacity b satisfies B3≧b>B2 when the number of charging times is 400 to 599. The possible number of settlements is specified as 3. Further, when the number of times the battery 30 has been charged is 850 times and the remaining battery level b of the battery 30 is 32%, the number of times of charging exceeds 800 times, the remaining battery level b corresponds to B1=b, and the remaining number of settlements possible. is specified as 1. Further, when the number of times of charging is 500 and the remaining battery capacity b is 33%, it is determined that the remaining battery capacity is sufficient because it is greater than B5 in the battery table. Also, when the number of times of charging is 500 and the remaining battery capacity b is 18%, B1 is less than 22%, so it is determined that immediate charging is required.

Next, the process flow of the battery state monitoring process for the process related to payment of the payment terminal 10 according to the embodiment of the present invention will be described with reference to FIG. When the power is turned on, the settlement terminal 10 executes the monitoring process shown in FIG. 9, and continues the monitoring process until the power is turned off. It should be noted that the following monitoring processing is performed only when the device is driven by the battery 30, and is not performed when the device is driven with the AC adapter 12 connected.

First, in step S<b>100 , the battery monitoring unit 36 measures the temperature of the battery 30 , reads out the number of charging times stored in the storage unit 34 , and measures the remaining battery capacity b of the battery 30 . Then, each reference value of the battery table stored in the storage unit 34 is referred to for the measured value of the temperature, the number of times of charging, and the measured value of the remaining battery capacity b.

In step S102, the battery monitoring unit 36 determines whether the remaining battery level b satisfies b≧B1 based on the reference result of each reference value in the battery table. , b≧B1, the process proceeds to step S118.

In step S104, the battery monitoring unit 36 determines whether or not the payment terminal 10 has been operated, and if it has been operated, the process proceeds to step S106, and if it has not been operated, it waits for an operation, and repeats the determination of whether or not it has been operated. , waiting to accept an operation.

In step S106, the battery monitoring unit 36 determines whether the received operation is payment processing. If the payment processing, the process proceeds to step S110.

In step S108, the payment terminal 10 executes processing other than payment, and returns to step S100. Processing other than payment includes, for example, confirmation of an ID recorded in the payment terminal 10 and confirmation of the number of charging times.

In step S<b>110 , the battery monitoring unit 36 measures the temperature of the battery 30 , reads the number of charging times stored in the storage unit 34 , and measures the remaining battery capacity b of the battery 30 . Then, each reference value of the battery table stored in the storage unit 34 is referred to for the measured value of the temperature, the number of times of charging, and the measured value of the remaining battery capacity b.

In step S112, the battery monitoring unit 36 determines whether the remaining battery level b is b>B5, B5≧b≧B1, or b<B1 based on the reference result of each reference value in the battery table. If b>B5, the process proceeds to step S114. If B5≧b≧B1, the process proceeds to step S116. If b<B1, the process proceeds to step S118.

In step S114, the payment terminal 10 executes payment processing, and proceeds to step S104.

In step S116, the battery monitoring unit 36 displays on the display unit 24 how many more payments can be made based on the reference result of each reference value in the battery table.

In step S<b>118 , the battery monitoring unit 36 displays on the display unit 24 a prompt for prompt charging, performs control so that the settlement process cannot be executed, and ends the monitoring process.

As described above, according to the settlement terminal according to the embodiment of the present invention, the remaining number of settlements that can be made with respect to the reference value of the battery temperature, the reference value of the charging history of the battery, and the reference value of the remaining battery level are specified in advance. By referring to the table obtained, the remaining number of possible payments corresponding to the acquired temperature, charging history, and remaining battery level is determined. This makes it possible to determine the number of remaining payments that can be made according to the battery usage conditions such as the usage environment and the degree of deterioration of the battery. In addition, it displays the number of remaining settlements possible, or displays a content prompting prompt charging when the remaining battery level is less than a threshold. By visualizing the remaining number of possible payments in this way, it is possible to prompt charging at an appropriate timing, thereby suppressing interruption of payments due to power outages.

The present invention is not limited to the above-described embodiments, and various modifications and applications are possible without departing from the gist of the present invention.

For example, in the above-described embodiment, the case where the remaining number of possible payments is set to 5 or more has been described as an example, but it is not limited to this. Any number of remaining settlements may be set according to the situation.

In addition, in the above-described embodiment, the case of displaying the remaining number of possible payments was explained as an example, but the present invention is not limited to this. may be notified by voice.

In the above-described embodiment, the payment terminal uses the number of times of charging as the charging history, but the present invention is not limited to this. For example, as the charging history, the transition of the voltage of the battery may be monitored, and the degree of deterioration that can be estimated from the voltage transition may be used as the charging history.

Further, in the above-described embodiment, the reference value of the remaining battery level in the battery table is defined to be B5 to B1 based on the reference that the battery consumption per payment is 2%, but this is not the only value. not to be For example, when the number of times of charging becomes large, the reference values of B5 to B1 may be determined by dividing by 3% or more.

In the above-described embodiment, the case where the settlement terminal uses two reference values, ie, when the temperature is 10° C. or higher and when the temperature is lower than 10° C., is described as an example, but the present invention is not limited to this. not something. For example, temperature reference values subdivided into three or more subdivided values such as below 5° C., below 10° C., and above 10° C. may be used.

Further, in the above-described embodiment, the settlement terminal uniquely identifies and displays the remaining number of possible settlements, but the present invention is not limited to this. For example, rather than explicitly displaying the remaining number of possible payments, the number of possible payments can be determined with a certain range, such as several times, 1-2 times, 5-6 times, etc. It is also possible to display the number of remaining settlements that have been set. In addition to displaying the remaining number of possible payments, fuzzy expressions such as "You need to charge the battery soon" and "Let's charge the battery after this payment is completed!" can be As a result, the operator can gradually recognize how much more payment is required and charging is required.

In the above-described embodiment, a battery table prescribing the reference value of the battery temperature, the reference value of the charging history of the battery, and the remaining possible number of settlements with respect to the reference value of the remaining battery power is referred to, and the obtained temperature , the charge history, and the remaining available number of payments corresponding to the remaining battery power are determined. However, by preparing a battery table corresponding to one or two types of reference values, such as remaining battery power and charging history, remaining battery power and temperature, and remaining battery power only, the remaining battery power, charging history, Instead of using all three temperature values, the number of remaining possible payments may be determined.

For example, if the usage environment is always warm, only the battery table for 10° C. or higher in FIG. may

Further, for example, in the case of a device whose number of times of charging is unknown, a state in which the number of times of charging is large is assumed in anticipation of safety. For example, a battery table (not shown) is prepared that stores the reference value of the remaining battery charge for each temperature when the number of charging operations in FIG. The number of remaining payments that can be made may be determined according to the remaining battery power.

Also, for example, in the case of a payment terminal for which only the remaining battery charge is known, the battery table of the reference value of the remaining battery charge only under the most severe condition ((2) below 10° C., 800 or more charging times) in FIG. is stored, and this condition may be used to determine the number of remaining payments that can be made according to the remaining battery level.

By doing so, even for a payment terminal that cannot obtain all the information on temperature, charging history, and remaining battery power, it is possible to make payments a little more times by obtaining at least the remaining battery power. It is possible to suppress the occurrence of the problem of using the battery to a charging level that cannot complete a series of transactions related to payment.
