Method for the use of mobile telephones as "ticket" for bus or train journeys. A user registers transaction parameters relating to the user, service and transaction status via his user terminal to a transaction processor. There are various variants possible for the inspection process: the inspector can request and check the user parameters via his terminal, via the user terminal or via both. The transaction processor can additionally transmit a status code to the inspector and/or user that can optionally be compared with a verification code. The status code and verification code can also be regularly and synchronously "refreshed", so that both codes change regularly, but are always identical to each other, provided that the transaction parameters of the user indicate legal use of the service. |
