Field of the Invention The present invention relates to a method of exchanging symbols of different types of electronic values while maintaining anonymity, using a transaction device capable of mutually transferring symbols of electronic values. In the description below, electronic money (electronic cash) will be described as an example of one of the symbols of electronic value.

転する技術については既に実現されている。2. Description of the Related Art When a foreign currency exchange procedure is constructed by combining conventional electronic money transfer technologies, a process for obtaining an agreement on transactions between a user and a currency exchange shop (currency exchange merchant), and a process in which the user enters a currency exchange shop. A process for paying electronic money of the first currency type and a process for the currency exchange shop to pay out electronic money of the second currency type to the user are required. As a combination of these, (1) a method of establishing a communication session between the two and executing the three processes therein, and (2) a method of executing the three processes separately in some communication sessions Is feasible.
However, in the related art, when a communication session is divided into a plurality of sessions, it is not possible to confirm the identity of users in a series of communication sessions. On the other hand, technology for transferring electronic money between the first transaction device and the second transaction device while maintaining anonymity has already been realized.

Similarly, this method cannot cope with a case where the consensus building process and the electronic money exchange process are to be performed asynchronously, for example, a case where the electronic money is exchanged after a certain period of time after the agreement is established.

Also, in this method,
When different communication sessions are required for transmission and reception of electronic money, for example, cases where separate servers are used for transmission and reception of electronic money cannot be handled.
Similarly, this method cannot cope with a case where payment of electronic money of the first currency type and payment of electronic money of the second currency type are performed asynchronously.

(2) a step in which the first transaction device pays electronic money of the first currency type to the second transaction device;
Separates the steps for the second transaction device to pay out the electronic money of the second currency type to the first transaction device.

完了する（Ｓ４）。[0013] User A establishes a first communication session between the first transaction device and a second transaction device in a currency exchange shop (S1). Next, the user A converts the electronic money of the yen (the first currency type) held in the IC card (the first transaction device) owned by the user A into the electronic money of $ 10 (the amount W2 of the second currency type). In order to exchange money, it is necessary to prove to the exchange shop server (second transaction device) that the user A is in the first communication session at the exchange shop B in the amount of $ 10 and the user A in the subsequent communication session. Data XX1 is transmitted as appropriate user identification data (S2). The second transaction device of the exchange shop B sets transaction conditions (for example, sets a transaction condition of selling for 1500 yen in response to a request to buy $ 10), and then trades the transaction conditions with the user identification data and the user identification data. A contract signed by the exchange shop with the information such as ID and expiration date is signed by the user A in the first place.
