[origin: WO9418580A1] Remote data transfert (10) unit of the type comprising a stationary beacon (11) and a mobile transponder (12). The invention also concerns the corresponding transponder. According to the invention, the data are exchanged between the beacon and the transponder by coding of a microwave signal. The signal, when, emitted by the beacon, is amplitude modulated; the signal, when emitted by the transponder, is phase or amplitude modulated. The transponder is characterized in that it accommodates a removable memory card (21), on which it can read or write said data. The transponder is also fitted with a compact and low cost antenna.
