• transmits a settlement request for settlement of the currency amount and the authentication information to the server if a result of the judgment is true;
• and
• displays a settlement completion notice, which reports completion of the settlement of the currency if a settlement completion response is received from the server,
• wherein the touch operation on the store-side UI is to make a contact site group, which is composed of one or more contact sites to contact the touch screen at the same time, of a store stamp which is a unit including the contact site group, touch the touch screen,
• wherein the contact site group has a feature specific to the store, and

A non-transitory computer-readable medium storing contents that, when executed by a computer including a touch screen, cause the one or more computers to:

• accept designation of a currency amount of a digital local currency;
• display, on the touch screen, a UI (User Interface) in which a user-side UI for accepting a touch operation by a user and a store-side UI for accepting a touch operation by a staff member of a store are placed, as a settlement UI for settlement of the currency amount, wherein the touch operation on the store-side UI also serves as input of authentication information of the store;
• judge whether time during which the touch operation on the user-side UI and the touch operation on the store-side UI are simultaneously continued has reached a specified period of time or not;
• transmit a settlement request for settlement of the currency amount and the authentication information to a server if a result of the judgment is true;
• and
• display a settlement completion notice, which reports completion of the settlement of the currency if a result of the judgment is true,
• wherein the touch operation on the store-side UI is to make a contact site group, which is composed of one or more contact sites to contact the touch screen at the same time, of a store stamp which is a unit including the contact site group, touch the touch screen,
• wherein the contact site group has a feature specific to the store, and
• wherein the authentication information is stamp information which is information representing the feature of the contact site group.
