EXCLUSIVE-LOCK CONTROL METHOD FOR RADIO COMMUNICATION DEVICE

A radio communication device includes, a radio communication device includes, a plurality of IC chips that conducts radio communicate with a reader/writer, a first setting unit that sets one IC chip selected from the plurality of IC chips to an exclusive-lock release state that allows radio communication to be conducted with the reader/writer, a determination unit that determines whether the radio communication is being conducted normally when radio communication between the one IC chip set to the exclusive-lock release state and the reader/writer is conducted, and a second setting unit that sets the one IC chip set to the exclusive-lock release state to a exclusive-locked state that does not allow radio communication with the reader/writer when the radio communication is determined as not being conducted normally, and sets another IC chip that is different from the one IC chip set to the exclusive-locked state to the exclusive-lock release state.
