摘要
The method involves receiving an initial signal from an interface device after transmission of response to charging of a portable object. The signal is sampled based on one of two frequencies associated with respective protocols. The sample is compared with a key condition of a protocol suitable to one protocol for processing data exchanged between the object and device according to a communication protocol. - Independent claims are also included for the following: - (a) a portable object to exchange the date with an interface device; and - (b) a computer program stored in an information medium for a method of processing data exchanged between a portable object and an interface device.
