Abstract
A method of making available personalization data in respect of a service between a terminal and a device. The terminal is able to communicate with the device on a first near-field channel and on a second wireless channel distinct from the first channel. The method includes, on the terminal, the steps of: obtaining a first message on the first channel, comprising at least one random datum; transmission on the second channel of a second message in response to the first message; establishment of a communication session on the second channel with the device; calculation of a secret datum as a function of the random datum received; transmission of the secret datum on the second channel; reception of a request for a personalization datum; transmission of at least one personalization datum in response to the request.
