  Next, a specific configuration example of the reader device 88 provided in the mobile phone 50 will be described with reference to FIG. The control unit 201 includes a CPU 211, a ROM 212, a RAM 213, an SCC (Serial Communication Controller) 214, an SPU (Signal Processing Unit) 216, and a bus 215 that interconnects these CPUs 211 to SPU 216.

  The CPU 211 develops the control program stored in the ROM 212 in the RAM 213, and performs various processes based on, for example, response data transmitted from the non-contact IC card 89 and control signals supplied from the CPU 52 in FIG. Execute. For example, the CPU 211 generates a command to be transmitted to the non-contact IC card 89 and outputs the command to the SPU 216 via the bus 215 or performs authentication processing of data transmitted from the non-contact IC card 89. To do.

  The SCC 214 supplies the data supplied from the CPU 52 in FIG. 4 to the CPU 211 via the bus 215, the data supplied from the CPU 211 to the CPU 211 via the bus 215, or the data supplied from the CPU 211 via the bus 215. The received data is output to the CPU 52.

  When the response data from the non-contact IC card 89 is supplied from the demodulator 208, the SPU 216 performs, for example, BPSK demodulation (Manchester code decoding) on the data, and sends the acquired data to the CPU 211. Supply. In addition, when a command to be transmitted to the contactless IC card 89 is supplied via the bus 215, the SPU 216 performs BPSK (Binary Phase Shift Keying) modulation (coding to Manchester code) on the command and acquires the command. Data is output to the modulation unit 202.

  The modulation unit 202 performs ASK (Amplitude Shift Keying) modulation on a carrier wave having a predetermined frequency (for example, 13.56 MHz) supplied from the oscillation unit 203 based on data supplied from the SPU 216, and generates a modulated wave. Is output to the amplifying unit 204.

  The amplification unit 204 amplifies the modulated wave input from the modulation unit 202 and causes the antenna 206 to output the electromagnetic wave. The amplification unit 204 switches the output impedance value of the transmission system including the modulation unit 202, the amplification unit 204, and the antenna 206 from a plurality of values prepared in advance in accordance with an instruction from the output characteristic adjustment unit 205.

  Next, a specific configuration of the non-contact IC card 89 interlocked with the reader device 88 will be described with reference to FIG. The non-contact IC card 89 includes, for example, an antenna (loop antenna) 230 and a capacitor 231 shown in FIG. 8 and an IC in which other configurations are stored in one chip, and is provided in the mobile phone 50 using electromagnetic induction. A half-duplex communication with the reader device 88 is performed. However, the shape may not be a card shape. Further, the IC card is a name used for convenience of explanation and intends a function as described above or described later. For example, there is a FeliCa chip (registered trademark) that provides basically the same function as the non-contact IC card 89. That is, for example, if a FeliCa chip is mounted on a mobile phone, the mobile phone can be used in the same manner as the non-contact IC card 89.

  The CPU 211 expands the control program stored in the ROM 222 in the RAM 233 and controls the overall operation of the non-contact IC card 89. For example, when the electromagnetic wave radiated from the reader device 88 provided in the mobile phone 50 is received by the antenna 230, the CPU 211 includes an IC including a card identification number provided in the non-contact IC card 89 according to the received electromagnetic wave. The card information is notified to the reader device 88, or the history information of the commercial transaction is supplied to the reader device 88 in response to a request from the reader device 88.

  The LC circuit constituted by the antenna 230 and the capacitor 231 resonates with an electromagnetic wave having a predetermined frequency radiated from the reader device 88 or the like provided in the mobile phone 50 disposed in the vicinity. In the ASK demodulator 243, the interface unit 229 demodulates the modulated wave (ASK modulated wave) received via the antenna 230 by detecting the envelope and demodulates the demodulated data to the BPSK (Binary Phase Shift Keying) demodulator 232. Output.

  The interface unit 229 rectifies the AC magnetic field excited in the antenna 230 by the ASK demodulator 243, stabilizes it in the voltage regulator 241, and supplies it to each unit as a DC power source. The power of the electromagnetic wave radiated from the reader device 88 is adjusted so as to generate a magnetic field that covers the power necessary for the non-contact IC card 89 as described later.

  In addition, the oscillation circuit 244 of the interface unit 229 includes a PLL (Phase Locked Loop) circuit, and generates a clock signal having the same frequency as the clock frequency of the received signal.

  Further, when the interface unit 229 transmits a request for balance information or the like to the reader device 88 or the like provided in the mobile phone 50, for example, in response to data supplied from the BPSK modulation unit 228, for example, predetermined switching An element (not shown) is turned on / off, and the load of the antenna 230 is varied by connecting a predetermined load in parallel to the antenna 230 only when the switching element is in the on state.

  The ASK modulation unit 242 performs ASK modulation on the BPSK modulation unit supplied from the BPSK modulation unit 228 according to the load variation of the antenna 230, and transmits the modulation component to the reader device 88 via the antenna 230 (reader device 88). (Variable terminal voltage of the antenna) (load switching method).

  When the data demodulated by the ASK demodulator 243 is BPSK modulated, the BPSK demodulator 232 demodulates the data (decodes Manchester code) based on a clock signal supplied from a PLL circuit (not shown). The demodulated data is output to the data receiving unit 233. The data receiving unit 233 appropriately outputs the supplied data to the CPU 221. The CPU 221 stores this data in the RAM 223 or the EEPROM 224.

  Data stored in the EEPROM 224 is read by the CPU 221 and supplied to the data transmission unit 227. The BPSK modulation unit 228 performs BPSK modulation (coding into Manchester code) on the data supplied from the data transmission unit 227, and outputs it to the ASK modulation unit 224.

  The EEPROM 224 stores electronic money information and the like. The user can use this electronic money to settle the price for purchased products, services, and the like. The settlement history is also stored in the EEPROM 224.

  Here, an example of the specification of the non-contact IC card 89 will be described. As described above, communication between the reader device 88 and the non-contact IC card 89 is performed in half duplex, and the communication speed is, for example, 211.875 kbps.

  The center frequency of the frequency band used for power transmission and data transfer from the reader device 88 to the contactless IC card 89 and data transfer from the contactless IC card 89 to the reader device 88 is, for example, 13.56 MHz. Is done.

  As described above, data transfer from the reader device 88 to the non-contact IC card 89 is performed by ASK modulation of data encoded in the Manchester code, and the modulation degree (maximum amplitude of data signal / maximum amplitude of carrier wave). ) Is, for example, about 0.1. Further, as described above, the data transfer from the non-contact IC card 89 to the reader device 88 converts the output data into a transmission signal by the load switching method (the antenna is turned on / off according to the output data). The load of 206 is changed).

  Using the function of the reader device 88 described above, the user can record the history information of the transaction (settlement) stored in the non-contact IC card 89 or the electronic information stored in the non-contact IC card 89 (charged). Money balance information can be displayed on the LCD 77 of the mobile phone 50.

  That is, the user operates the input operation unit 71 of the mobile phone 50 to start an application for performing the above-described processing, and places the non-contact IC card 89 at the position of the reader device 88 on the back side of the casing of the mobile phone 50.

Thereafter, communication authentication is performed between the Bluetooth module 13 of the in-vehicle device 10 and the Bluetooth module 84 of the mobile phone 50. If they do not match, the process proceeds to another process and information transfer is not performed.

  On the other hand, if the authentication matches, the shared information is compared, and the CPU 45 of the in-vehicle device 10 determines whether or not the device 1 needs to be updated. If it is determined that it is necessary, the in-vehicle device 10 acquires information from the mobile phone 50 and updates it. Next, the CPU 45 of the in-vehicle device 10 determines whether it is necessary to update information from the mobile phone 50 to the in-vehicle device 10. If it is determined that the update is necessary, the information is updated from the mobile phone 50 to the in-vehicle device 10.
