Abstract
A radio frequency identification (RFID) communication system and the search method thereof are disclosed, which apply search instructions and reads instructions to communicate between a read and a plurality of transponders. Each transponder generates a random number for comparison with received search instructions. When the random number meets with the number of received search instructions, a response request is sent by a corresponding transponder such that the reader can read the content of the corresponding transponder.
