It may be transmitted (S41).
상기 웨이크 업 신호 및 무선전력이 수신된 경우, 상기 수동형 RFID 칩(200)에 구비된 제1스위치(스위치 A, 281)가 온 되어, 1차 전원 회로가 온 된다(S42, S43).When the wake-up signal and the wireless power are received, the first switch (switch A, 281) provided in the passive RFID chip 200 is turned on, and the primary power circuit is turned on (S42, S43).

상기 제1전원 및 상기 제2전원 중 어느 하나가 공급되는 상태에서는 상기 통신 모듈(300)은 무선 통신 단말기(20)와 통신을 수행하여 상호 데이터를 교환할 수 있다(S47).In a state in which one of the first power source and the second power source is supplied, the communication module 300 may communicate with the wireless communication terminal 20 to exchange data with each other (S47).
한편, 상기 통신 장치(100)가 상기 RF 리더기(10)와 소정 거리 이상 떨어진 경우, RF 리더기(10)에서 상기 수동형 RFID 칩(200)에 공급되는 무선전력의 공급은 중단된다(S48).On the other hand, when the communication device 100 is separated from the RF reader 10 by more than a predetermined distance, the supply of wireless power supplied to the passive RFID chip 200 from the RF reader 10 is stopped (S48).
상기 무선전력의 공급이 중단되면, 상기 제1스위치(스위치 A, 281)는 오프되어, 1차 전원 회로가 오프된다(S49, S50).When the supply of the wireless power is stopped, the first switches (switches A and 281) are turned off, and the primary power circuit is turned off (S49 and S50).
1차 전원 회로가 오프되면, 제1전원의 공급이 중단된다. 제1전원이 중단된다 하더라도, 상기 통신 모듈(300)이 상기 무선 통신 단말기(20)와 통신을 수행하는 경우에는 제2전원의 공급은 계속 유지된다.When the primary power supply circuit is turned off, the supply of the first power supply is stopped.

In addition, the communication module 300 may use a frequency of 400Mhz or more for the smooth communication of the wireless.
