Abstract: According to an embodiment of the present invention a method for detecting fraudulent use of credit cards is herein described. In the case when possible fraudulent use is detected the issuer or other responsible party, such as a third-party mediator, temporarily blocks the credit card account. This can be accomplished, for example, by making an artificial excess of credit limit of the credit card or otherwise temporarily closing a credit card account. In some embodiments an issuer or responsible party may send a warning message and/or alert to a client's mobile phone informing of an upcoming temporary block of client's credit card.

Abstract: The invention relates to a method and system for booking reservations in a booking system and synchronizing bookings among several booking systems. The system comprises at least one booking system; at least one service provider; a mediator service; a client, and at least one client terminal device that can be a mobile device and that includes a dialog. The client uses the dialog to enter information into the system and the mediator receives inquiries and answers from the at least one booking system, the at least one service provider, and the at least one client. The mediator transfers and adapts information between them. The method and system are particularly suited for use with mobile phone users by Small Message Service messages.
