Currency exchange method and device using web server providing unmanned information terminal and currency exchange website

摘要

An unmanned information terminal and an exchange method using a web server providing a website and a device thereof are provided to perform foreign exchange in a country where a person conveniently travels, thereby reducing an exchange fee, time and efforts. A receipt document displaying price of money inserted into an unmanned information terminal, a currency nationality and an encrypted intrinsic identification sign for checking a transaction is issued from a printing device(150~154). Contents displayed on the receipt document are classified in a central information processing center(158). A user suggests the intrinsic identification sign to an exchange transaction website. An exchange rate that the website suggests is applied to paper money shown on the receipt document to perform exchange.
