  • Short-range wireless communication apparatus and cellular phone terminal
    Patent number: 8567685
    Abstract: There is provided a short-range wireless communication apparatus and a cellular phone terminal that can surely and immediately notify a user of the optimum distance between a contactless IC card reader/writer and a contactless IC card not through an MPU or a CPU and if the contactless IC card function is locked, surely notify the user as such. In an RFID card, a magnetic field strength/brightness conversion section adjusts the brightness of two LEDs in accordance with the detected magnetic field strength of a carrier wave. A blink generation circuit detects whether the RFID card is in a communication state and blinks the LEDs if so. A function combining section combines the functions to indicate the magnetic field strength and the communication state with the brightness and blinking of the LEDs. An LED with another color illuminates only when an RFID function LSI is in a lock state.
