Here, when TE2 is placed on the terminal installation unit 13 of POS1, radio waves are transmitted and received between the antenna units of TE2 and POS1, and near-field wireless communication becomes possible by the wireless communication unit of both TE2 and POS1. Shall be
(Authentication process of mobile terminal)
FIG. 5 shows a flowchart of an embodiment of the authentication process performed by the portable terminal TE of the present invention.
Here, when TE2 is placed on the terminal installation unit 13 of POS1, it is in a state where wireless communication by NFC is possible, and after confirming that POS1 is a connectable device, it is correlated with the usage level of TE2. The transaction processing is performed by activating a predetermined function in the POS 1 that has been stored.

In step S1 of FIG. 5, the ID transmission unit 45 reads the terminal number (TE-ID) 51 of its own from the storage unit 50, and the TE-ID 51 is read via the NFC connection unit 42b of the wireless communication unit 42. Send by NFC.
In step S2, it is confirmed whether there is reception of data by NFC via the NFC connection unit 42b.
In step S3, it is checked whether data corresponding to POS-ID has been received.
If no data has been received or if data corresponding to POS-ID has not been received, the process returns to step S1.
On the other hand, if the data corresponding to the POS-ID is received, the process proceeds to step S4.
The processes from steps S1 to S3 may be repeated at regular time intervals (for example, every second).

In step S4, based on the data corresponding to the received POS-ID, it is checked whether the device that has transmitted the POS-ID is a device capable of NFC connection.
Here, the received POS-ID is compared with the POS-ID 52 stored in advance in the storage unit 50.
If the POS-IDs match in step S5, it is determined that the POS 1 that has transmitted the POS-ID is a device that can be connected, and the process proceeds to step S6.
On the other hand, if the POS-IDs do not match, it is determined that the POS 1 that has sent the POS-ID is a device that can not be connected to its own TE 2, and the process returns to step S 1.
In this flow, it is determined whether or not the POS 1 is a connectable device by receiving the POS-ID from the POS 1 of the communication partner, but the present invention is not limited to this, and data meaning connection permission from the POS 1 When it is determined that the POS 1 is a connectable device, and when data indicating no connection is received, it may be determined that the POS 1 is not a connectable device.

In step S6, the POS authentication unit 46 performs pairing with the POS using NFC, and performs predetermined authentication processing.
Here, pairing means authenticating each other for security maintenance so as not to communicate with unrelated devices. For example, pairing is performed between TE and POS by confirming whether the device has an ID for which connection is permitted when NFC communication is possible.
Then, when it is confirmed that the connection is permitted, it is determined that the authentication is successful, and each other is registered, and the communication becomes possible. On the other hand, if it can not be confirmed, it is determined that the authentication has failed and communication can not be performed.
In step S7, if the authentication is successful, the process proceeds to step S9. If not, the process proceeds to step S8.
In step S8, an error message indicating that the authentication could not be performed is displayed on the display unit 43, and then the process returns to step S1.

FIG. 8 shows a transition diagram of one embodiment of a change of the display screen displayed on the display unit of the portable terminal TE of the present invention.
FIG. 8- (1) shows an example of a display screen before the person in charge holds TE2 and uses it alone, or before the authentication process is performed.
FIG. 8- (2) shows an example of displaying an error message when authentication fails.
For example, as shown in FIG. 8- (2), this terminal TE2 displays that it is not a terminal that can be connected to POS1 (it is not a POS terminal).

In view of the error message displayed in step S8, the person in charge knows that the terminal TE2 possessed by the self can not be connected to the POS 1 and that settlement processing can not be performed.
In order to carry out the settlement process, the person in charge should go to another sales management device POS1 where connection with the possession terminal TE2 is permitted in advance, and place TE2 on the terminal installation unit 13 of the POS1. Good.
In addition, a third party brings a terminal TE having a TE-ID not stored in advance in POS 1 or a terminal TE that can not be paired with POS to the POS 1 close to the terminal installation unit 13 with an unfair purpose. Even in this case, authentication fails, so normal settlement processing can not be performed, and sufficient security is secured.

In step S9, since the authentication is successful, unlocking processing of the function that can be executed by the POS 1 is performed.
At this time, as shown in FIG. 8-(3), a message indicating that authentication has succeeded (a POS terminal is detected. A POS application is activated) may be displayed on the display unit 43.
In the unlocking process, when the TE 2 is not placed on the terminal installation unit 13, the function that has not been permitted to be executed by the POS 1 alone is validated, and the connected device can also be used. However, the lock is released so that only the functions previously permitted by the usage level of TE2 can be used.
For example, in TE2 whose usage level is "A", connection control of input / output devices such as scanners and printers is enabled, input operation to these devices from TE2 is enabled, and information on purchased goods is input to the display unit And displays a display screen on which settlement can be performed, and transmits input information to the POS 1 using the touch panel of the TE 2 so that settlement processing using the POS 1 can be executed.
In step S10, the function of POS 1 is executed to start an application program for performing transaction processing.
Thereafter, as shown in FIG. 8-(4), the display screen at the time of transaction processing is displayed, and transaction processing as shown in FIG. 9 or 10 described later is executed. After the person in charge places TE 2 on the terminal installation unit 13 of the POS 1, step S 10 is executed, and it is not necessary to perform a special input operation by the person in charge until the display screen is displayed.

(Authentication process of sales management device)
FIG. 6 shows a flowchart of an embodiment of the authentication process performed by the sales management device POS of the present invention.
Here, when TE2 is placed on the terminal installation unit 13 of POS1, communication by NFC becomes possible between TE2 and POS1, and after confirming that TE2 is a device connectable to POS1, TE2 can be connected. Activate the function of POS1 associated with the usage level of, and activate the permitted connection device to execute transaction processing.

In step S21 of FIG. 6, the ID acquiring unit 14 confirms whether data is received by NFC via the NFC connection unit 12b.
In step S22, data is received by NFC, and it is checked whether the received data is the terminal number TE-ID unique to TE2 stored in the storage unit 50 of TE2.
If the TE-ID has not been received, the process returns to step S21.
On the other hand, if the TE-ID is received, the process proceeds to step S23.
For example, when TE2 is placed on the terminal installation unit 13, NFC communication is enabled between the antenna units of TE2 and POS1, and the terminal number TE-ID transmitted from TE2 is received.
However, in this flow, POS1 waits for the TE-ID to be transmitted from TE2, but the present invention is not limited to this, and transmitting the TE-ID from the POS 1 side at regular intervals. The requested information may be transmitted.

In step S23, the terminal authentication unit 15 confirms whether the terminal TE of the received TE-ID is a connectable terminal.
Specifically, the received TE-ID is compared with the terminal number TE-ID in the terminal identification information 21 stored in the storage unit 20, and the received TE-ID matches the received TE-ID in the information 21. Check if something exists.
If the received TE-ID is present in the terminal identification information 21, it is determined that the TE 2 that has transmitted the received TE-ID is a terminal permitted to be connected.
On the other hand, when the received TE-ID is not stored in the terminal identification information 21, it is determined that the TE2 that has transmitted the received TE-ID is a terminal that does not permit connection.
If it is determined in step S24 that the terminal TE that has transmitted the TE-ID is a connectable terminal as a result of the confirmation, the process proceeds to step S25. If not, the process returns to step S21.

In step S25, the identification number POS-ID 22 of the POS 1 is read from the storage unit 20, and the POS-ID 22 is transmitted via the NFC connection unit 12b.
In step S26, pairing with TE2 is performed, and the same predetermined authentication processing as shown in step S6 is performed.
In step S27, if the authentication is successful, the process proceeds to step S28. If the authentication is unsuccessful, the process returns to step S21.

In step S28, of the functions provided in the POS 1, the lock release processing of the function whose execution has been restricted is performed.
The unlocking process here is performed with reference to the usage level preset in the terminal identification information 21 of the storage unit 20. That is, the usage level associated with the received TE-ID in the terminal identification information 21 is confirmed, and the function of the POS permitted by the usage level is validated. Thereby, it becomes possible to execute the transaction processing by the commodity transaction processing unit 19.
For example, in TE2 whose usage level is "A", control of connected devices such as a scanner and data transmission / reception of input transaction information and the like are enabled.
In step S29, data communication with the TE 2 using NFC is performed, and based on the data communication content, an application program for connection device control for operating the connection device is activated.

The above is the embodiment of the authentication process performed between TE2 and POS1.
In this invention, when a clerk in charge of a TE 2 such as a store clerk in charge of a store settles a purchased product after serving, TE2 is installed on the terminal of POS 1 where the TE-ID of that TE 2 is already set. The authentication process as shown in FIG. 5 and FIG. 6 is automatically executed only by the operation of placing it on the unit 13.
After the person in charge installs the TE 2 in the terminal installation unit 13, the person in charge does not need to perform any input operation until the transaction processing can be executed after the authentication process between the TE and the POS succeeds. Input burden can be reduced.
Further, unlike the conventional POS system, there is no need to carry around the key without using the mode key or the Clark key, and there is no risk of losing the key, and in this respect, sufficient security can be secured.
However, when the person in charge holds the portable terminal TE2 for customer service, there is a risk of losing the portable terminal TE2 itself, but generally the size of the portable terminal is larger than the key, It is thought that it is easier to find than the key even if it is misplaced, and the possibility of loss is considered to be less. Moreover, since the settlement process etc. becomes possible by using TE2 and POS1 in combination, even if only TE2 is lost and is used by a third party, the processing necessary for sales operations can be executed with TE2 alone. And sufficient security can be secured.

(Second embodiment of sales management system)
In addition, if the fixed position of the portable terminal TE is the terminal installation unit 13 of the POS 1 in which the TE-ID is set and stored, and the customer does not carry out the TE 2 except at the time of customer service, the risk of losing the TE 2 Can be reduced.
Furthermore, if NFC communication is made possible simply by placing the portable terminal TE2 on the terminal installation unit 13, it is easy for the person in charge to handle the TE2, although the TE2 can be easily attached and detached. Since there is a risk that a person brings out the TE 2, after the TE 2 is placed on the terminal installation unit 13, the lock may be semi-fixed so that it can not be easily removed.
Further, unlike the conventional POS system, there is no need to create a plurality of keys, and there is no need to provide a mechanism for inserting the key in the POS main body, and the POS and the portable terminal TE having the communication function by NFC can be Since an application program for executing the authentication process and the transaction process may be implemented, simplification of the configuration and cost reduction of the entire system including TE and POS can be achieved.

<Transaction processing using a portable terminal and a sales management device>
FIG. 9 is an explanatory view of one example of the display screen displayed on the portable terminal TE2 and the input operation when the transaction processing is performed.
FIG. 10 is a sequence diagram of one embodiment of transaction processing performed between the portable terminal TE2 and the sales management device POS1 of the present invention.
As described above, when the TE 2 is placed on the terminal installation unit 13 of the POS 1 and the authentication process is successful, the display screen as shown in FIG. 8-(4) is displayed to start the transaction process.
FIG. 9- (1) shows the same display screen at the start of the transaction as FIG. 8- (4).
Here, a ten-key pad, a transaction start input button, and a display column of the input product information and amount are displayed.
It is assumed that the touch panel 44a is disposed so as to be superimposed on the display screen.
In step SB1 of FIG. 10, a person in charge contacts and inputs a display area on the “start transaction” screen of FIG. 9- (1) to start a transaction.
When a transaction start input is made, data indicating a transaction start request is transmitted from TE 2 to POS 1 using NFC.

In step SA1, when the POS 1 receives the transaction start request, data indicating the transaction start permission is transmitted to the TE 2.
When the TE 2 receives the transaction start permission, for example, as shown in FIG. 9-(2), it becomes a display state where information such as a purchased product can be input.
In step SA2, it is assumed that the person in charge operates the scanner to read the barcode attached to the purchased product.
At this time, data that requests to transmit scanner data is transmitted from POS1 to TE2.
In step SB2, when the TE 2 receives a transmission request for scanner data, the transmission permission is transmitted to the POS 1.
In step SA3, when the POS 1 receives the transmission permission, the barcode data read by the scanner is transmitted to the TE 2.

In step SB3, when the TE 2 receives the barcode data, it transmits a barcode reception completion notification to the POS 1.
Further, the received barcode data is analyzed, and information (product name, number, etc.) of the product read by the barcode is displayed.
Further, using the product information 53 of the storage unit 50, the amount of the purchased product is calculated and displayed on the display screen.
For example, as shown in FIG. 9- (2), a product name and a subtotal are displayed.
If there are a plurality of purchased products, the processing from step SA2 to SB3 is repeated for each purchased product.
Thereafter, when the information of all the purchased products is input, in step SB4, a display area meaning settlement is selected and input. As a result, the settlement preparation request is transmitted from TE2 to POS1.

When POS1 receives the settlement preparation request in step SA4, the settlement preparation permission is transmitted to TE2.
In step SB5, when the TE 2 receives the settlement preparation permission, it transmits to the POS 1 a settlement display preparation request requesting display of the settlement information.
In step SA5, when the POS 1 receives the above request, the settlement display preparation completion is transmitted to the TE 2.
In step SB6, after performing the settlement process of the purchased product, the TE 2 generates display information of the purchased product, and transmits the display information to the POS 1.
In step SA6, the POS 1 displays the received information of the purchased product on the display screen of a display device (not shown) provided on the POS 1 for showing the information to the customer.
The person in charge shows the display to the customer to confirm whether the purchased product or the purchase price is correct.
Also, the settlement method is determined by inquiring the customer about the settlement method, that is, cash payment, credit card settlement, or other settlement method.

For example, when making a payment by credit card, in step SB7, the display screen 43 of FIG. 9- (3) is displayed on the display unit 43 of TE2, and a person in charge selects a display area meaning card payment do that for me.
By this selection input, the TE 2 transmits to the POS 1 data for requesting a read settlement of a credit card.
In step SA7, the person in charge performs an operation of reading a credit card using the card reader of POS1.
By this reading operation, the information stored in the credit card is read out, and after a predetermined user authentication process is executed, an inquiry confirmation of the validity of the card information is performed to the credit card company.
When the inquiry confirmation is normally completed, the card reading and settlement completion notification is transmitted from the POS 1 to the TE 2.

In step SB8, when the TE 2 receives the completion notice, as shown in FIG. 9 (4), the display screen displays a confirmation indicating that the card settlement is completed.
If the person in charge looks at this display and selects and inputs a display area for confirmation of completion of card payment, the TE2 sends a receipt print request to POS1.
In step SA8, when the POS 1 receives the receipt printing request, the receipt printing permission is transmitted to the TE 2.
In step SB9, when the TE 2 receives the receipt print permission, the receipt print information is generated, and the generated receipt print information is transmitted to the POS 1.
In step SA9, when the POS 1 receives the receipt print information, the printer 1 transmits the print information to execute receipt printing.
After receipt printing is completed, a receipt print completion notification indicating that the printing is completed is sent from POS 1 to TE 2.

In step SB10, when the TE 2 receives the receipt print completion notification, the display unit 43 displays a message indicating that the transaction has been completed, and ends the transaction processing.
Thereafter, in the case of executing different transaction processing, the transaction processing is started by returning to step SB1 and performing the transaction start input.
