Abstract
A method involving a mode for detecting the protocol implemented within and by a portable object. After transmission of a response upon turning on the portable object, an initial signal is received from the interface device. The initial signal is sampled according to at least one of the first and second speeds associated with the first and second respective protocols. In the portable object, at least one sample of a resulting sampling signal is compared to at least one key protocol condition proper to one of the first and second protocols. According to the result of the comparison, the data exchanged according to one of the first or second communication protocols is processed in the portable object.
