Abstract (en)

[origin: WO0235466A1] The invention concerns non-contact smart cards and, more particularly in such cards, a circuit for detecting data frames and providing them with a parallel format for their processing. The invention is characterised in that it consists in using the information contained in the first octets to determining the number of octets of the frame being currently received, thereby enabling to identify them as they are received and route them into registers (80). This is provided by a state machine (60) whereof the shift from one state to the other is switched by the circuitry (62, 76) output signals.
