TOKEN TRADING

摘要

The invention concerns trading tokens, such as but not limited to, the trading of virtual trading cards. The invention also concerns a computer system (104) to facilitate the trading of tokens, a set of messages exchanged in order to trade tokens, a method of trading tokens by a token owner, and a software application to be used by the token owner to trade a token. Information relating to tokens owned by the first and second user is stored in a datastore. Using their mobile device (100), a first user (102) offers to trade a first token, and this offer is stored in the datastore (104). The server (104) then sends to the mobile communication device (112) of a second user (110) details of the offer. The second user (110) can reply by offering a second token in exchange for the first token, and this offer is also stored in the datastore and communicated to the first user (102). The first user (102) can accept the offer using their mobile device (102) and the datastore is automatically updated so that the ownership of the tokens following the exchange is recorded accordingly in the data store.
