Settlement system and settlement method
According to one embodiment, a settlement system includes a server and a merchant device. The server includes a rate notification unit and a payment controller. The rate notification unit notifies the device of an exchange rate. The payment controller pays the amount to the device in a currency of a second country. The device includes a display controller and a sales notification unit. The display controller displays on a terminal of a user an amount of payment for purchase of an article in a currency of a first country. The sales notification unit reports to the server the sales information in the currency of the first country. Upon receipt of an image that contains an article, the display controller calculates the amount of payment for purchase of the article in the currency of the first country, and displays the calculated amount of payment on the image.
