Abstract

A portable terminal includes a wireless communication adopter and a processor. The wireless communication adopter executes wireless communication with a commodity sales data processing apparatus. The processor executes settlement processing on the basis of commodity information and in response to receiving the commodity information containing a price of a commodity from the commodity sales data processing apparatus via the wireless communication adopter. Additionally, the processor transmits, via the communication adopter, settlement information resulting from the settlement processing, to the commodity sales data processing apparatus.

What is claimed is: 
     
         1 . A portable terminal, comprising:
 a wireless communication adopter that executes wireless communication with a commodity sales data processing apparatus; and   a processor that executes:   settlement processing on the basis of commodity information and in response to receiving the commodity information containing a price of a commodity from the commodity sales data processing apparatus via the wireless communication adopter; and   transmission processing via the wireless communication adopter to transmit settlement information resulting from the settlement processing, to the commodity sales data processing apparatus.   
     
     
         2 . The portable terminal according to  claim 1 , wherein the processor executes:
 transmission processing to transmit a request for shopping history information via the wireless communication adopter to the commodity sales data processing apparatus, and   reception processing to receive the shopping history information via the wireless communication adopter.   
     
     
         3 . The portable terminal according to  claim 2 , wherein the processor executes:
 transmission processing to transmit a request for recommendation information identifying a recommended commodity via the wireless communication adopter, and   reception processing to receive the recommendation information via the wireless communication adopter.   
     
     
         4 . The portable terminal according to  claim 1 , further comprising
 a display that displays a checkout key enabling a commodity to be registered, wherein   the processor executes:   transmission processing to transmit a signal to the commodity sales data processing apparatus via the wireless communication adopter, the signal indicating that the checkout key is operated in accordance with an operation of the checkout key displayed; and   the settlement processing on the basis of the settlement information received from the commodity sales data processing apparatus in accordance with the signal that is transmitted.   
     
     
         5 . The portable terminal according to  claim 4 , wherein
 the display further displays a settlement key; and   the processor executes, if the settlement key is operated, the settlement processing on the basis of the settlement information received from the commodity sales data processing apparatus.   
     
     
         6 . A communication method for a portable terminal, the method comprising:
 executing a communication with a commodity sales data processing apparatus via a wireless communication adopter;   executing settlement processing on the basis of commodity information and in response to receiving the commodity information containing a price of a commodity from the commodity sales data processing apparatus via the wireless communication adopter; and   executing transmission processing via the wireless communication adopter to transmit settlement information resulting from the settlement processing, to the commodity sales data processing apparatus.
