Embodiments of the present invention will be described below with reference to the drawings.
[First Embodiment]
First, a first embodiment of the present invention will be described.
FIG. 1 is a block diagram showing a configuration example of an embodiment of a POS system according to the present invention. As shown in FIG. 1, in the present embodiment, the POS system 1 includes a store controller 10, two product registration devices 20, and four checkout devices 30. The store controller 10, the two product registration devices 20, and the four checkout devices 30 are connected to each other via a wired or wireless LAN (Local Area Network) 11.

  The configuration of the POS system 1 shown in FIG. 1 is an example, and for example, the number of the merchandise registration apparatus 20 and the settlement apparatus 30 can be further increased or decreased. Further, the store controller 10 and the product registration device 20 and the checkout device 30 are not necessarily connected via the LAN 11. In this case, data exchange can be performed using power line communication that realizes high-speed communication using electric wiring. It is also possible to omit the store controller 10 by having the product registration device 20 have the function of the store controller 10.

  The store controller 10 is a computer that controls the POS system 1 and manages various information such as a product master. Further, the store controller 10 appropriately transmits the latest product master to the product registration device 20 and each checkout device 30. Here, the product master is a file that stores product information such as product identification information, product name, and sales price of each product, and is appropriately updated. Further, the store controller 10 manages the settlement status of each transaction. For example, the store controller 10 stores a payment status data table indicating the payment status of each transaction, and notifies the product registration device 20 of the payment status of each transaction.

The merchandise registration apparatus 20 performs processing for registering data of merchandise to be purchased by the customer. Data registration is performed, for example, by reading a barcode attached to a product.
Therefore, the merchandise registration apparatus 20 is provided with a scanner that reads, for example, a bar code attached to a merchandise purchased by a customer by a store clerk.

  Further, the merchandise registration apparatus 20 selects the settlement apparatus 30 that settles the transaction in which the merchandise data is registered. Then, the merchandise registration apparatus 20 transmits data related to the transaction to the selected settlement apparatus 30. The data relating to the transaction includes a transaction number for identifying the transaction, the amount of all products registered in the transaction, that is, the total amount, the product code of the registered product, and the like. The product code is identification information for identifying a product. The customer of the transaction can perform the settlement process by operating the settlement apparatus 30 to which the data relating to the transaction is transmitted. The checkout process is a process of paying and paying for a product to be purchased by selectively using cash, electronic money, a credit card, or the like.

  In addition, when the product registration device 20 transmits the data related to the transaction, the merchandise registration device 20 displays to which clerk or customer the settlement device 30 the data related to the transaction is transmitted. For example, when displayed to the store clerk, the store clerk can verbally tell the customer. The display method in this case is arbitrary. For example, it can be performed by highlighting the transmitted settlement apparatus 30 on a touch panel or the like installed for the store clerk in the product registration apparatus 20. Moreover, you may make it display the guidance which shows the settlement apparatus 30 of a transmission destination on the display part which faced the customer side which the merchandise registration apparatus 20 has. Alternatively, a receipt for guiding the corresponding settlement apparatus 30 (for example, a number tag receipt on which the number of the settlement apparatus 30 is printed) may be issued and handed to the customer.

  Further, the merchandise registration apparatus 20 may print all purchase contents of the merchandise purchased by the customer. In this case, the customer can confirm the registration contents using the merchandise registration apparatus 20 by looking at the print result before operating the settlement apparatus 30 to perform the settlement process.

  Moreover, the merchandise registration apparatus 20 can change the settlement apparatus 30 that settles the transaction. The clerk manually selects the settlement apparatus 30. For example, the store clerk determines the status of the settlement apparatus 30 and changes the settlement apparatus 30 that settles the transaction on the touch panel. Thereby, for example, when the customer's queue is made in the selected checkout apparatus 30, or when a failure occurs in the automatic change machine of the checkout apparatus 30, the other checkout apparatus 30 can make payment. .

  On the other hand, the settlement apparatus 30 is an apparatus for a customer to perform settlement processing by himself / herself, and includes an automatic change machine, a card reader (for example, for credit cards and point cards), and an RF (Radio Frequency) reader (for example, electronic money). For payment).

  Further, when the settlement apparatus 30 receives the data relating to the transaction from the merchandise registration apparatus 20, the settlement apparatus 30 notifies (that is, guides the customer) so that the customer can come to the settlement apparatus 30. As an example of notification, for example, displaying character information such as a predetermined number on the entire screen of the display unit of the settlement apparatus 30 is displayed. The character information such as the number is information that the product registration device 20 (or the clerk operating the product registration device 20) separately notifies the customer. For example, the customer may go to the checkout device 30 displaying his / her own number informed. As another notification example, there is guidance by turning on a predetermined lamp included in the settlement apparatus 30. For example, it lights up with a specific color, and the customer goes to the checkout device 30 of the designated color. Further, it may be flashing. As another notification example, the member card No may be displayed on the screen of the settlement apparatus 30. This membership card No is read by the product registration device 20, for example. The customer goes to the checkout apparatus 30 that notifies his / her membership card No.

  Moreover, the payment apparatus 30 will be in a standby state after alert | reporting. That is, the settlement apparatus 30 is in a state of waiting for an instruction to start the settlement process corresponding to the received transaction data after performing the notification. As an example of canceling the standby state, for example, when the customer touches the display screen of the settlement apparatus 30 (or presses any button), the settlement process is automatically started. Until the screen is touched, nothing is displayed on the screen, or for example, only the number is displayed as in the above notification example. Alternatively, the settlement apparatus 30 may start the settlement process by detecting whether or not the customer has approached using a human sensor. Also in this case, the screen can be made non-displayed or number-displayed until it is detected. When the human settlement sensor 30 detects the approach of a person, the settlement apparatus 30 starts the settlement process. Alternatively, a camera can be used instead of the human sensor. For example, a camera may be installed in the checkout apparatus 30 and the product registration apparatus 20, and the checkout process may be started only when the same person approaches in face recognition.

Moreover, the flow of the adjustment process with respect to the adjustment apparatus 30 in a standby state can be performed as follows, for example. (1) First, a payment method is selected. Either cash, credit card, electronic money or the like is selected according to the customer's operation. (2) Next, settlement is executed. Settlement is executed by inserting cash into a bill / coin input / output port, payment of change, or reading a card with a card reader.
(3) Next, a receipt is issued using the printing unit of the checkout apparatus 30.
On the receipt, for example, a list of purchased products, a total purchase amount, a received amount, a fishing amount, and the like are printed. (4) Then, the settlement apparatus 30 ends the settlement process and enters an empty state.

  Note that the settlement method in the settlement apparatus 30 may be reported by the product registration apparatus 20.
