Abstract: A method for transferring data between a lottery system and a participant to the lottery system is described. The participant participates in a lottery game via a mobile communication device such as a mobile telephone. The method comprises the steps of transferring a non confidential part of the data between the communication device and the system via a first communication channel, such as a SMS channel. In response to the transfer of the non confidential part of the data, a confidential part of the data is transferred between the participant and the system via a second, secure communication channel, such as a voice response channel, a wireless access protocol (WAP channel) or an internet connection.
