Patent ID: 8200162

Claim:
A method for minimizing interference of an RFID reader built in a mobile terminal, the method comprising the steps of: a) detecting an identity number of the mobile terminal and a mobile communication network signal for synchronizing the mobile terminal with a base station; b) allocating sequential identification numbers (0, 1, 2, . . . , N−1) to basic information units constituting a cycle of the mobile communication network signal, the basic information units arranged in time order; c) dividing the identity number of the mobile terminal by the number (N) of basic information units constituting the cycle of the mobile communication network signal; d) assigning an operating time of the reader to a particular basic information unit of the mobile communication network signal allocated the identification number identical to a remainder of the identity number of the mobile terminal, the identity number divided by the number of the basic information units; and e) outputting an electromagnetic wave for detecting a specific tag for the assigned operating time.
