Abstract
A method for handling collision in an identification system where the identification system includes a reader, a first transponder and a second transponder. The method involves the reader transmitting 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 where the first transponder and the second transponder do not respond to commands from the reader; 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 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 sends a mute command to the second transponder.
