In a method of transferring data from a transponder to a reading device in
a scanning identification system through load-modulation of an inquiry
signal emitted by the reading device, with the transponder being
initialized at the beginning of the reception of the inquiry signal and
responding with the emission of the response signal, first a predetermined
number of data bits that are not part of the response signal are
transmitted, and a terminator sequence followed by the response signal are
repeatedly transmitted, until the inquiry signal is interrupted. The time
required by the reading device for building up the inquiry field is
bridged by the predetermined number of data bits and, at the same time,
the reading device is synchronized to the clock of the response signal.
Through the terminator sequence, which indicates the beginning of a valid
response signal, the response signal is already recognized correctly by
the reading device during the first transfer.
