  Hereinafter, preferred embodiments of the present invention will be described using the drawings. In addition, this invention is not limited to the following embodiment, In the range which does not deviate from the summary, it can change suitably. The same or corresponding components in the drawings may be denoted by the same reference numerals, and the description thereof may be omitted or simplified.

First Embodiment
FIG. 1 is a view schematically showing a POS system 100 according to the first embodiment. The POS system 100 of the present embodiment is configured to include the portable terminal 1, the POS device 2, and the beacons 3 a and 3 b. The POS system 100 of this embodiment can be applied to, for example, sales management in a supermarket, convenience store, department store, restaurant, hospital, and the like.

  The portable terminal 1 is, for example, a tablet terminal, and is used as a POS terminal for performing an operation to control the POS apparatus 2. The portable terminal 1 is miniaturized so as to be portable, and is further configured to be able to control the POS device 2 wirelessly. By making the POS device 2 controllable by wireless communication from the portable terminal 1 that can be carried, compared with the case of adopting a wired connection such as performing an operation by connecting the portable terminal 1 to a cradle. The convenience of the operator (store clerk) can be improved.

  The portable terminal 1 and the POS apparatus 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 portable terminal 1 and the POS device 2 may be mutually connected by wireless communication based on a short distance wireless communication standard such as Bluetooth (registered trademark), for example. .

  The POS device 2 has POS peripheral devices such as the cash storage unit 21. The cash storage unit 21 is provided to be able to open in the direction of the arrow on the operation side of the POS apparatus 2 shown in FIG. 1 based on control from the portable terminal 1. The cash storage unit 21 can store cash and the like. When the cash storage unit 21 is in the open state, the operator can carry out cash in and out. The POS apparatus 2 may further include, as a POS peripheral device, a barcode scanner for reading a barcode attached to a product, a printer for printing a receipt, and the like.

  The POS device 2 is installed on the service stand 4a because the POS device 2 and the POS peripheral device included in the POS device 2 are often not suitable for carrying. The service stand 4a is used as a counter for meeting the salesclerk and the customer and providing services such as sales. The POS apparatus 2 may be fixed to the service stand 4a, and the POS apparatus 2 may be mounted on the service stand 4a. The POS device 2 may be more generally referred to as a fixed terminal. The “fixed terminal” is not limited to the fixed state in a non-removable state, as long as the terminal is not a terminal that is carried during normal use. Therefore, even if the POS apparatus 2 is mounted without being fixed to the service stand 4a, such a POS apparatus 2 is included in the "fixed terminal". Further, even if a part of the POS apparatus 2 is provided with a detachable part such as a hand scanner, if the entire POS apparatus 2 is not intended to be carried at the time of use, such a POS apparatus 2 is Included in "fixed terminal".

  The beacons 3a and 3b are devices conforming to the BLE (Bluetooth Low Energy) standard. BLE is a low power short distance wireless technology, including a beacon based location information detection technology. The beacons 3a and 3b transmit beacon signals to the ranges of the radio areas Ra and Rb at predetermined time intervals. The portable terminal 1 determines whether to permit control from the portable terminal 1 to the POS apparatus 2 based on the strength of the beacon signal received from the beacons 3a and 3b. The beacons 3a, 3b may be more generally referred to as wireless transmitters. Also, the beacon 3a may be referred to as a first wireless transmitter, and the beacon 3b may be referred to as a second wireless transmitter.

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

  In this case, assuming that the outputs of the beacon signals transmitted by the beacons 3a and 3b are the same, the strength of the beacon signal received by the portable terminal 1 corresponds to the distance from the beacon. Specifically, in the operation area R of the POS apparatus 2, the strength of the beacon signal received from the beacon 3a is larger 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, by performing correction as appropriate, the strength of the beacon signal received from the beacon 3a and the strength of the beacon signal received from the beacon 3b are portable. It is possible to determine the position of the terminal 1. The intensity of the beacon signal may be, for example, an electric field intensity.

  Therefore, the portable terminal 1 determines permission of control from the portable terminal 1 to the POS apparatus 2 based on 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. . 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 larger than a predetermined threshold, the portable terminal 1 permits control of the POS apparatus 2 Do. Therefore, when the operator of the POS apparatus 2 operates the portable terminal 1 in the operation area R, control of the POS apparatus 2 can be permitted. On the other hand, when the operator of the POS apparatus 2 operates the portable terminal 1 from the outside of the operation area R of the POS apparatus 2, control of the POS apparatus 2 is not permitted. This improves security.

  The reason why such control by the portable terminal 1 leads to the improvement of security will be described in more detail. In the normal operation state, the operator operates the portable terminal 1 in the operation area R on the clerk side of the POS apparatus 2. However, the operator may go out of the operation area R with the portable terminal 1 for product description and the like. At this time, the operator may perform an erroneous operation of controlling the POS apparatus 2 from the outside of the operation area R of the POS apparatus 2, for example, 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 temporarily, it is possible for a third party to access cash or the like in the cash storage unit 21.

  At this time, when the cash storage unit 21 is opened due to an erroneous operation, the operator manually closes the opened cash storage unit 21. As shown in FIG. 1, when the service stand 4a on which the POS apparatus 2 is installed has a horizontally long shape, the operator bypasses the service stand 4a to close the cash storage unit 21 and operates it. It is necessary to move to the area R, and the POS device 2 will be largely separated. In this case, the possibility that a third party accesses 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 apparatus 2 operates the portable terminal 1 from the outside of the operation area R of the POS apparatus 2, control such as opening operation of the cash storage unit 21 to the POS apparatus 2 is permitted. I will not. Therefore, even when the operator performs an erroneous operation such as an operation to open the cash storage unit 21, this operation is invalidated. Thus, the situation where a third party as described above accesses cash or the like in the cash storage unit 21 is avoided. Therefore, a POS system with more improved security is provided.

  In the above description, information on 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 instead of the beacons 3a and 3b as long as it is a method of obtaining information on the position of the portable terminal 1 using a plurality of wireless transmitters. . For example, a wireless transmitter conforming to a Bluetooth standard other than BLE may be employed. However, since BLE is a low power consumption wireless technology, the use of BLE has the effect of reducing power consumption.

  In addition, as a technique which can be used for specifying a position, GPS (Global Positioning System), wireless LAN etc. are mentioned besides the above-mentioned thing. However, by adopting a beacon conforming to BLE, the following effects can be obtained compared to the case of adopting these techniques. Beacons that conform to BLE have the advantage of being able to be used indoors for GPS, and thus are better suited to POS systems that are often used in stores. Beacons conforming to BLE have smaller measurement errors in position than wireless LANs.

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

  The beacon signal transmitted from the beacons 3a and 3b includes ID (Identifier) information for identifying the POS apparatus 2. The ID information may be any ID information that 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 portable terminal 1 inquires of the management server 6 based on the same ID information included in the beacon signal received from the beacons 3a and 3b, and acquires the IP (Internet Protocol) address of the POS apparatus 2. The storage device 7 of the management server 6 stores a table in which the correspondence between the ID information of the POS apparatus 2 and the IP address is recorded. The beacon signal transmitted from the beacons 3a and 3b may include the IP address of the POS apparatus 2. In this case, the management server 6 and the storage device 7 can be omitted. Thus, the ID information, management information and IP address used to identify the POS device 2 may be more generally referred to as identification information.

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

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

  The POS apparatus 2 shown in FIG. 2B is configured to have a network printer 24 connected to a POS peripheral device (cash storage unit 21). The portable terminal 1 is wirelessly connected to the network printer 24 via the wireless access point 5. The portable 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 capable of controlling a POS peripheral device and having an interface connectable to a network may be used. In this configuration, the portable terminal 1 may be responsible for part of the POS function.

  FIG. 3 is a block diagram schematically showing the configuration of the portable terminal 1 according to the first embodiment. The portable terminal 1 includes a beacon receiving unit 11, a storage unit 12, a POS control permitting unit 13, and a POS control unit 14. The beacon receiver 11 may be simply referred to as a receiver. The POS control permission unit 13 may be simply referred to as a determination unit. Although not shown in FIG. 3, the portable terminal 1 has an input unit for performing data input and the like, a display unit for displaying the result of processing, a communication unit for performing communication with the POS apparatus 2, and And a control unit that controls the above-described units.

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 receiving unit 11 may be, for example, a network interface provided in the mobile terminal 1. In the storage unit 12, arrangement information including information on how the beacons 3a and 3b are arranged around the POS apparatus 2 is registered in advance. The storage unit 12 may be, for example, a non-volatile storage medium such as a flash memory provided in the mobile terminal 1.

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

  When control to the POS apparatus 2 is permitted by the POS control permitting unit 13, the POS control unit 14 controls the corresponding POS apparatus 2 based on the identification information included in the beacon signal received from the beacons 3a and 3b. Establish a communication connection. Then, the POS control unit 14 controls POS peripheral devices such as the cash storage unit 21, the printer 22, and the barcode scanner 23 via the POS device 2.

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

  In step S103, whether or not the POS control permission unit 13 permits control from the POS control unit 14 to the POS apparatus 2 based on at least one of the beacon signal received from the beacon 3a and the beacon signal received from the beacon 3b. Determine When the control to the POS apparatus 2 is not permitted by the POS control permitting unit 13 in step S103 (NO in step S103), this processing ends.

  Thereby, the operator of the POS apparatus 2 can be prevented from erroneously operating the portable terminal 1 from outside the operation area R of the POS apparatus 2 to control the POS peripheral device of the POS apparatus 2.

  On the other hand, when control to the POS apparatus 2 is permitted by the POS control permitting unit 13 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 apparatus 2 based on the ID information included in the beacon signal received from the beacons 3a and 3b. In step S105, the POS control unit 14 controls the POS peripheral device via the POS apparatus 2.

  As described above, the portable terminal 1 according to the present embodiment includes 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 the determination, permission of control from the POS control unit 14 to the POS apparatus 2 is determined.

  According to such a configuration, it is possible to provide a portable terminal, a control method therefor, a POS system and a program in which security in controlling a fixed terminal is further improved.

Second Embodiment
FIG. 5 is a view schematically showing a POS system 100 according to the second embodiment. The POS system 100 of this embodiment is different from the one shown in FIG. 1 of the first embodiment in the arrangement of the beacons 3a and 3b. In the following, only the points different from FIG. 1 will be described, and the points common to FIG. 1 will not be described.

  In the POS system shown in FIG. 5, the beacons 3 a and 3 b are arranged to sandwich the operation area R of the POS apparatus 2. More specifically, the beacon 3a is disposed on the service stand 4a in which the POS apparatus 2 is disposed, and the beacon 3b is disposed on the opposite side of the service stand 4a across the operation area R, that is, on the clerk side. It is arranged in the service stand 4b. The service stand 4b is not limited to this, and may be any fixture such as a shelf, a desk, a locker, and the like.

  In this case, in the operation area R of the POS apparatus 2, it is possible to receive beacon signals from both of the beacons 3a and 3b. Therefore, when the strength of the beacon signal received from the beacon 3a and the strength of the beacon signal received from the beacon 3b are both greater than a predetermined threshold, the POS control permitting unit 13 sends the POS control unit 14 to the POS apparatus 2 Allow control of In the other cases, the POS control permitting unit 13 does not permit the control from the POS control unit 14 to the POS apparatus 2. Thereby, the operator of the POS apparatus 2 can be prevented from erroneously operating the portable terminal 1 from outside the operation area R to control the POS peripheral device of the POS apparatus 2.

  According to such a configuration, as in the first embodiment, it is possible to provide a portable terminal, a control method therefor, a POS system and a program, in which security in controlling a fixed terminal is further improved.

  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 may be different from each other.

  Further, the processing in the POS control permission unit 13 controls the POS control unit 14 to control the POS apparatus 2 when both the beacon signal transmitted from the beacon 3a and the beacon signal transmitted from the beacon 3b can be received. It may be one that permits.

Third Embodiment
FIG. 6 is a view schematically showing a POS system 100 according to the third embodiment. The POS system 100 of this embodiment is different from the one shown in FIG. 1 of the first embodiment in the arrangement of the beacons 3a and 3b. In the following, only the points different from FIG. 1 will be described, and the points common to FIG. 1 will not be described.

  In the POS system shown in FIG. 6, the beacon 3a is disposed on the clerk side of the POS apparatus 2, and the beacon 3b is disposed on the customer side opposite to the clerk side of the POS apparatus 2.

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

  In this case, in the operation area R of the POS apparatus 2, the portable terminal 1 can receive a beacon signal from the beacon 3a. However, the portable terminal 1 can not receive the beacon signal from the beacon 3 b or the reception strength becomes very small. Therefore, the POS control permitting unit 13 determines that the strength of the beacon signal received from the beacon 3a is larger than the first threshold and the strength of the beacon signal received from the beacon 3b is smaller than the second threshold smaller than the first threshold. If the size is too small, the control from the POS control unit 14 to the POS apparatus 2 is permitted. Thereby, the operator of the POS apparatus 2 can be prevented from erroneously operating the portable terminal 1 from outside the operation area R to control the POS peripheral device of the POS apparatus 2.

  According to such a configuration, as in the first embodiment, it is possible to provide a portable terminal, a control method therefor, a POS system and a program, in which security in controlling a fixed terminal is further improved.

  The processing in the POS control permitting unit 13 permits the control of the POS control unit 14 from the POS control unit 14 when only the signal transmitted from one of the beacon 3a and the beacon 3b can be received. It is also good.

  The portable terminal described in the above first to third embodiments can also be configured as in the following fourth embodiment.
