Elements having the same or corresponding functions in each figure are denoted by the same reference numerals, and their description may be omitted or simplified.

(First embodiment)
FIG. 1 is a diagram schematically showing a POS system 100 according to the first embodiment. A POS system 100 of the present embodiment includes a mobile terminal 1, a POS device 2, and beacons 3a and 3b. The POS system 100 of this embodiment can be applied, for example, to sales management in supermarkets, convenience stores, department stores, restaurants, hospitals, and the like.

The mobile terminal 1 is, for example, a tablet terminal, and is used as a POS terminal for performing operations for controlling the POS device 2 . The mobile terminal 1 is miniaturized so as to be suitable for carrying, and is configured to be able to wirelessly control the POS device 2 . By configuring the POS device 2 to be controllable by wireless communication from the mobile terminal 1, which is portable, compared to the case of adopting a wired connection such as connecting the mobile terminal 1 to a cradle and operating it. , convenience for the operator (clerk) can be improved.

The mobile terminal 1 and the POS device 2 can be mutually connected by wireless LAN communication via a wireless LAN access point. However, the present embodiment is not limited to this, and the mobile terminal 1 and the POS device 2 may be connected to each other by wireless communication based on a short-range wireless communication standard such as Bluetooth (registered trademark). .

The POS device 2 has POS peripheral devices such as the cash storage unit 21 . The cash storage unit 21 is provided so as to be openable in the direction of the arrow on the operating side of the POS device 2 shown in FIG. Cash and the like can be stored in the cash storage unit 21 . When the cash storage unit 21 is in the open state, the operator can take out cash or the like. The POS device 2 may further include, as POS peripheral devices, a barcode scanner for reading barcodes attached to products, a printer for printing receipts, and the like.

Since the main body of the POS device 2 and the POS peripheral devices included in the POS device 2 are often not suitable for portability, the POS device 2 is installed on the service stand 4a. The service table 4a is used as a counter where a clerk and a customer face each other to provide services such as sales. The POS device 2 may be fixed to the service table 4a, or the POS device 2 may be placed on the service table 4a. POS device 2 may also be more commonly referred to as a fixed terminal. Note that the "fixed terminal" is not limited to a state in which it is fixed in an unremovable state as long as it is a terminal that is not carried during normal use. Therefore, even if the POS device 2 is placed on the service table 4a without being fixed, such a POS device 2 is included in the "fixed terminal". Also, even if a part of the POS device 2 has a detachable part such as a hand scanner, if the POS device 2 as a whole is not portable during use, such a POS device 2 Included in “fixed terminals”.

The beacons 3a and 3b are devices conforming to the BLE (Bluetooth Low Energy) standard. BLE is a short-range wireless technology with low power consumption, and includes location information detection technology using beacons. The beacons 3a and 3b transmit beacon signals within radio ranges Ra and Rb, respectively, at predetermined time intervals. The mobile terminal 1 determines whether or not to permit control of the POS device 2 from the mobile terminal 1 based on the strength of the beacon signals received from the beacons 3a and 3b. The beacons 3a, 3b are sometimes referred to more generally as radio transmitters. Also, beacon 3a may be referred to as a first radio transmitter and beacon 3b may be referred to as a second radio transmitter.

In the POS system 100 shown in FIG. 1, the beacon 3a is arranged on the clerk side with respect to the POS device 2, and the beacon 3b is arranged on the customer side opposite to the clerk side from the beacon 3a. Here, the beacon 3b may be placed closer to the customer than the beacon 3a, and the positional relationship between the beacons 3a and 3b and the POS device 2 is not particularly limited as long as it is placed closer to the customer. For example, as shown in FIG. 1, the beacon 3b may be placed above the POS device 2. FIG.

In this case, if the beacon signals transmitted by the beacons 3a and 3b have the same output, the strength of the beacon signal received by the mobile terminal 1 depends on the distance from the beacon. Specifically, in the operation area R of the POS device 2, the strength of the beacon signal received from the beacon 3a is greater than the strength of the beacon signal received from the beacon 3b. Alternatively, even if the outputs of the beacon signals transmitted by the beacons 3a and 3b are different, the strength of the beacon signal received from the beacon 3a and the strength of the beacon signal received from the beacon 3b can be determined by performing appropriate correction. It is possible to determine the location of terminal 1 . Note that the strength of the beacon signal may be, for example, the electric field strength.

Therefore, the mobile terminal 1 determines permission to control the POS device 2 from the mobile terminal 1 based on the difference and magnitude relationship between the strength of the beacon signal received from the beacon 3a and the strength of the beacon signal received from the beacon 3b. . More specifically, when the difference between the strength of the beacon signal received from the beacon 3a and the strength of the beacon signal received from the beacon 3b is greater than a predetermined threshold, the mobile terminal 1 permits control of the POS device 2. do. Therefore, when the operator of the POS device 2 operates the mobile terminal 1 within the operation area R, control over the POS device 2 can be permitted. On the other hand, when the operator of the POS device 2 operates the mobile terminal 1 from outside the operation area R of the POS device 2, control over the POS device 2 is not permitted. This improves security.

The reason why the mobile terminal 1 performing such control leads to an improvement in security will be described in more detail. In a normal operation state, the operator operates the mobile terminal 1 in the operation area R on the clerk's side of the POS device 2 . However, the operator may go out of the operation area R with the portable terminal 1 in order to explain the product or the like. At this time, the operator may erroneously control the POS device 2 from outside the operation area R of the POS device 2, for example, from the customer side. An example of this erroneous operation includes an operation to open the cash storage unit 21 . At this time, if the cash storage unit 21 is opened, a third party can access cash or the like in the cash storage unit 21 .

At this time, if the cash storage unit 21 is opened by an erroneous operation, the operator manually closes the open cash storage unit 21 . As shown in FIG. 1, when the service table 4a on which the POS device 2 is installed has a horizontally long shape, the operator bypasses the service table 4a in order to close the cash storage unit 21. It is necessary to move to the area R, and the POS device 2 is far away. In this case, the possibility of a third party accessing the cash or the like in the cash storage unit 21 increases.

On the other hand, in the present embodiment, when the operator of the POS device 2 operates the mobile terminal 1 from outside the operation area R of the POS device 2, control of the POS device 2, such as opening the cash storage section 21, is permitted. not. Therefore, even if the operator performs an erroneous operation such as an operation to open the cash storage unit 21, this operation is invalidated. This avoids a situation where a third party accesses the cash or the like in the cash storage unit 21 as described above. Therefore, a POS system with improved security is provided.

In the above description, the information about the position of the mobile terminal 1 is obtained using the beacons 3a and 3b conforming to BLE. However, the present invention is not limited to this, and any other device may be employed in place of the beacons 3a and 3b as long as it is a method of obtaining information regarding the position of the mobile terminal 1 using a plurality of wireless transmitters. . For example, a wireless transmitter complying with the Bluetooth standard other than BLE may be employed. However, since BLE is a radio technology with low power consumption, the use of BLE has the effect of reducing power consumption.

In addition to the technologies described above, other technologies that can be used to specify a position include GPS (Global Positioning System) and wireless LAN. However, by adopting a beacon conforming to BLE, the following effects can be obtained compared to the case of adopting these technologies. BLE-compliant beacons have the advantage over GPS that they can be used indoors, so they are more suitable for POS systems that are often used in stores. BLE-compliant beacons have smaller position measurement errors than wireless LANs.

2A and 2B are diagrams schematically showing examples of wireless connection between the mobile terminal 1 and the POS device 2 in the POS system 100 according to the first embodiment. The mobile terminal 1, POS device 2, wireless access point 5 and management server 6 constitute a LAN. A mobile terminal 1 is wirelessly connected to a wireless access point 5 . The wireless access point 5, management server 6 and POS device 2 are connected by wire. The beacons 3a and 3b are arranged around the POS device 2, and when the mobile terminal 1 approaches the beacons 3a and 3b, it receives the beacon signals transmitted from the beacons 3a and 3b. The wireless connection described above may be based on the IEEE 802.11 series of standards, for example. The above-described wired connection may be based on the Ethernet (registered trademark) standard, for example.

The beacon signals transmitted from the beacons 3 a and 3 b contain ID (Identifier) information for identifying the POS device 2 . The ID information may be anything as long as it can identify the POS device 2, and for example, the management number of the POS device 2 can be used. The ID information is registered in advance in the beacons 3a and 3b.

The mobile terminal 1 makes an inquiry to the management server 6 based on the same ID information included in the beacon signals received from the beacons 3 a and 3 b and acquires the IP (Internet Protocol) address of the POS device 2 . The storage device 7 of the management server 6 stores a table that records the correspondence between the ID information of the POS device 2 and the IP address. The beacon signals transmitted from the beacons 3a and 3b may contain the IP address of the POS device 2. FIG. In this case, the management server 6 and storage device 7 can be omitted. In this way, the ID information, management information, and IP address used to identify the POS device 2 may be more generally called identification information.

The mobile terminal 1 connects to the POS device 2 corresponding to the IP address acquired based on the ID information included in the beacon signal. The mobile terminal 1 controls POS peripheral devices such as the cash storage unit 21 , the printer 22 , and the bar code scanner 23 of the POS device 2 via the POS device 2 . The configuration of the POS device 2 can be, for example, as shown in FIG. 2A or 2B.

The POS device 2 shown in FIG. 2A is configured as a POS/PC connected to POS peripheral devices (cash compartment 21, printer 22 and barcode scanner 23). A mobile terminal 1 is wirelessly connected to a POS/PC via a wireless access point 5 . The mobile terminal 1 controls POS peripheral devices such as a cash storage unit 21, a printer 22, and a bar code scanner 23 via the POS/PC. As an example of POS/PC, for example, a PC installed with a POS system application can be used.

The POS machine 2 shown in FIG. 2B comprises a network printer 24 connected to a POS peripheral device (cash compartment 21). The mobile terminal 1 is wirelessly connected to the network printer 24 via the wireless access point 5 . The mobile terminal 1 controls POS peripheral devices such as the cash storage unit 21 via the network printer 24 . As an example of the network printer 24, for example, a printer that can control a POS peripheral device and has an interface that can be connected to a network can be used. In this configuration, the mobile terminal 1 may take part of the functions of the POS.

FIG. 3 is a block diagram schematically showing the configuration of the mobile terminal 1 according to the first embodiment. The mobile terminal 1 includes a beacon reception unit 11, a storage unit 12, a POS control permission unit 13, and a POS control unit 14. FIG. The beacon receiver 11 is sometimes simply called a receiver. The POS control permitting unit 13 is sometimes simply called a determination unit. Although not shown in FIG. 3, the mobile terminal 1 includes an input unit for inputting data and the like, a display unit for displaying processing results and the like, a communication unit for communicating with the POS device 2, and and a control unit for controlling each unit described above.

The beacon receiver 11 receives beacon signals transmitted from the beacons 3a and 3b. At this time, the beacon receiving unit 11 acquires the strength of the beacon signal transmitted from the beacon 3 a, the strength of the beacon signal transmitted from the beacon 3 b, and the identification information corresponding to the POS device 2 . The beacon receiver 11 may be a network interface provided in the mobile terminal 1, for example. Arrangement information including information on how the beacons 3 a and 3 b are arranged around the POS device 2 is registered in advance in the storage unit 12 . The storage unit 12 may be, for example, a non-volatile recording medium such as a flash memory provided in the mobile terminal 1 .

The POS control permitting unit 13 determines permission to control the POS device 2 from the POS control unit 14 based on the strength of the beacon signals transmitted from the beacons 3a and 3b and the arrangement information stored in the storage unit 12. do. The functions of the POS control permission unit 13 and the POS control unit 14 can be realized, for example, by a processor provided in the mobile terminal 1 reading a program from a recording medium provided in the mobile terminal 1 and executing the program.

When the POS control permission unit 13 permits control of the POS device 2, the POS control unit 14 controls the corresponding POS device 2 based on the identification information included in the beacon signals received from the beacons 3a and 3b. establish a communication connection; The POS control unit 14 controls POS peripheral devices such as the cash storage unit 21 , the printer 22 and the bar code scanner 23 through the POS device 2 .

FIG. 4 is a flow chart showing a control method of the mobile terminal 1 according to the first embodiment. In step S101, the beacon receiver 11 receives beacon signals transmitted from the beacons 3a and 3b. In step S102, the beacon receiving unit 11 measures and acquires the strength of the beacon signals received from the beacons 3a and 3b.

In step S103, the POS control permission unit 13 determines whether or not to permit control of the POS device 2 from the POS control unit 14 based on at least one of the beacon signal received from the beacon 3a and the beacon signal received from the beacon 3b. judge. If the POS control permitting unit 13 does not permit the control of the POS device 2 in step S103 (NO in step S103), this process ends.

This prevents the operator of the POS device 2 from erroneously operating the mobile terminal 1 from outside the operation area R of the POS device 2 to control the POS peripheral devices of the POS device 2 .

On the other hand, if the POS control permitting unit 13 permits control of the POS device 2 in step S103 (YES in step S103), the process proceeds to step S104. In step S104, the POS control unit 14 establishes a communication connection with the POS device 2 based on the ID information included in the beacon signals received from the beacons 3a and 3b. In step S<b>105 , the POS control unit 14 controls POS peripheral devices via the POS device 2 .

As described above, the mobile terminal 1 of the present embodiment can be used for the beacon signal transmitted from the first wireless transmitter (beacon 3a) and the beacon signal transmitted from the second wireless transmitter (beacon 3b). Based on this, it is determined whether the POS controller 14 is permitted to control the POS device 2 .

According to such a configuration, it is possible to provide a mobile terminal, a control method thereof, a POS system, and a program with improved security when controlling a fixed terminal.

(Second embodiment)
FIG. 5 is a diagram schematically showing a POS system 100 according to the second embodiment. The POS system 100 of this embodiment differs from that shown in FIG. 1 of the first embodiment in the arrangement of beacons 3a and 3b. In the following, points different from FIG. 1 will be described, and descriptions of points common to FIG. 1 will be omitted.

In the POS system shown in FIG. 5, the beacons 3a and 3b are arranged so as to sandwich the operation area R of the POS device 2. As shown in FIG. More specifically, the beacon 3a is arranged on the service table 4a on which the POS device 2 is arranged, and the beacon 3b is installed on the opposite side of the operation area R from the service table 4a, that is, on the clerk side. It is arranged on the service stand 4b. Note that the service table 4b is not limited to this, and may be any fixture such as a shelf, a desk, or a locker.

In this case, in the operation area R of the POS device 2, it is possible to receive beacon signals from both the beacons 3a and 3b. Therefore, the POS control permitting unit 13 sends a signal from the POS control unit 14 to the POS device 2 when both the strength of the beacon signal received from the beacon 3a and the strength of the beacon signal received from the beacon 3b are greater than a predetermined threshold. allow control of Otherwise, the POS control permitting unit 13 does not permit the POS control unit 14 to control the POS device 2 . This prevents the operator of the POS device 2 from erroneously operating the mobile terminal 1 from outside the operation area R to control the POS peripheral devices of the POS device 2 .

With such a configuration, as in the first embodiment, it is possible to provide a mobile terminal, a control method thereof, a POS system, and a program with improved security when controlling a fixed terminal.

The threshold for the strength of the beacon signal received from the beacon 3a and the threshold for the strength of the beacon signal received from the beacon 3b may be the same or different.

FIG. The service table 4c is not limited to this, and may be any fixture such as a shelf, chair, desk, locker, drawer, or the like.

In this case, in the operation area R of the POS device 2, the mobile terminal 1 can receive the beacon signal from the beacon 3a. However, the mobile terminal 1 cannot receive the beacon signal from the beacon 3b, or the reception strength becomes very low. Therefore, the POS control permitting unit 13 determines that the strength of the beacon signal received from the beacon 3a is greater than the first threshold and the strength of the beacon signal received from the beacon 3b is less than the second threshold, which is less than the first threshold. is smaller, the control from the POS controller 14 to the POS device 2 is permitted. This prevents the operator of the POS device 2 from erroneously operating the mobile terminal 1 from outside the operation area R to control the POS peripheral devices of the POS device 2 .

With such a configuration, as in the first embodiment, it is possible to provide a mobile terminal, a control method thereof, a POS system, and a program with improved security when controlling a fixed terminal.

The processing in the POS control permission unit 13 permits the control of the POS device 2 from the POS control unit 14 when only the signal transmitted from one of the beacons 3a and 3b can be received. good too.
