A method for handling collision in an identification system is provided, wherein the identification system comprises a reader device, a first transponder and a second transponder, and the method comprises the following steps: the reader device transmits an initialization command to the first transponder and to the second transponder; upon receiving the initialization command, the first transponder and the second transponder enter into a muted state, and in the muted state the first transponder and the second transponder do not respond to commands from the reader device; in a randomly determined first start time slot the first transponder enters into an un-muted state and the first transponder remains in the un-muted state until the reader device sends a mute command to the first transponder; in a randomly determined second start time slot the second transponder enters into an un-muted state and the second transponder remains in the un-muted state until the reader device sends a mute command to the second transponder. A corresponding identification system is also provided.
