The control output unit 20 drives, for example, a relay of a door lock mechanism, and when a control signal is supplied from the control unit 18 in a locked state of the door, the control output unit 20 drives the relay in a direction to unlock the door. On the other hand, when the control signal is supplied from the control unit 18 with the door unlocked, the relay is driven in the direction to lock the door. On the other hand, when the control unit 18 determines that the first ID information and the second ID information do not match, the control unit 18 does not output the control signal.

Here, the control unit 18 transmits / receives the second ID information stored in the memory unit 6 of the information card 1 to the transmission / reception coil 28.
The first ID information is not read from the magnetic card reader unit 15 until it is received by. On the contrary,
After receiving the second ID information, the first ID information is read. After reading the first and second ID information, these pieces of information are collated. Then, when it is determined in this collation that the first ID information and the second ID information match, a control signal is supplied to the control output unit 20. Also,
As will be described later, the green light emitting diode of the collation determination display section 21 is turned on. On the other hand, if it is determined that the first ID information and the second ID information do not match, the control signal is not supplied to the control output unit 20, and the collation determination display unit 2

The collation determination display section 21 is configured to have two light emitting diodes (not shown) for red and green as described above, and when the first ID information and the second ID information match, The green light emitting diode is turned on according to the coincidence signal output from the control unit 18. When the first ID information and the second ID information do not match, the red light emitting diode is turned on according to the mismatch signal output from the control unit 18. In this case, as is apparent, the green light emitting diode lights up if OK, and the red light emitting diode lights up if it is NG. The display unit 22 is made of EL (electroluminescence), liquid crystal, plasma display, or the like, and displays the first and second ID information stored in the data buffer memory unit 328. The 1/0 converter 24 converts the information output from the controller 18 into a predetermined code of "1" or "0".

Stored in 32. Data buffer memory unit 32
The information stored in is displayed on the display unit 22.

(C) Reading Mechanism of Card Reading Device FIG. 2 is a perspective view showing the structure of the reading mechanism of the card reading device 12 and the information card 11. In this figure, like the card reader for a normal magnetic card, the insertion slot 50 of the information card 1 and the carry-in rollers 51, 52 of the information card 1 are shown.
And the like, and a magnetic head 60 is arranged inside the magnetic stripe region 2 of the information card 1 so as to be in pressure contact therewith. When the information card 1 having the magnetic stripe area 2 formed therein is inserted into the card reading device 12, the magnetic card reader unit 15 reads the first ID information from the magnetic stripe area 2.

The operation of the above configuration will be described with reference to the flow charts shown in FIGS. B. Operation of Information Card and Card Reader (a) Operation of Information Card FIG. 3 is a flowchart showing the operation of the information card 1.
When the transmission / reception coil 4 of the information card 1 approaches the distance for receiving the radio wave transmitted from the card reader 12, an induced electromotive force is generated in the transmission / reception coil 4, and the induced electromotive force causes the power supply unit 3 to generate a power source. , IC circuit 7 is supplied. From this time, the control unit 5 starts operating.

First, in step S10, a read command consisting of "1" or "0" output from the 1/0 conversion unit 9 is fetched, the read command is decoded, and the read command of the designated memory area of the memory unit 6 is read. The ID information of No. 2 is read. Next, in step S12, the read second
The ID information of is supplied to the transmission / reception coil 4. This allows
The second ID information is transmitted. After the second ID information is supplied to the transmission / reception coil 4, the process proceeds to step S14, it is determined whether the address designation is completed, and if it is determined in this determination that another address is designated, the process returns to step S10. If it is determined that there is no other address designation, the process ends.

(B) Operation of Card Reading Device FIG. 4 is a flowchart showing the operation of the card reading device 12. First, in step S30, the control unit 18 supplies the read command to the 1/0 conversion unit 24 and converts the read command into a predetermined code of "1" or "0". This code information is supplied to the modulator 26. The modulator 26 modulates the signal from the oscillator 25 with the code information and supplies the modulated signal to the power amplifier 27. Then, the power-amplified modulated signal is supplied to the transmission / reception coil 28 and transmitted.

Next, the control unit 18 sets 1 in step S32.
The output of the / 0 converter 31 is captured, and it is determined in step S34 whether the 1/0 converter 31 has output the code information that is the second ID information. In this determination, if it is determined that the second ID information is output, the process proceeds to step S36, and the second ID information is stored in the data buffer memory unit 32. On the other hand, the second I
If it is determined that the D information is not output, step S30
Return to The second ID information is stored in the data buffer memory unit 32.
After storing it in step S38, the process proceeds to step S38, the output of the I / F unit 17 is fetched, and in step S40, the first
It is determined whether or not the ID information of is output. in this case,
When the magnetic card reader unit 15 reads the first ID information recorded in the magnetic stripe area 2 of the information card 1, the waveform-shaped first ID information is output from the I / F unit 17. To be done.

First ID in the determination in step S40
If it is determined that the information is output, the process proceeds to step S42, and the first ID information is stored in the data buffer memory unit 32.
To memorize. On the other hand, if it is determined that the first ID information is not output, the process of step S38 is repeated. After storing the first ID information in the data buffer memory unit 32, the process proceeds to step S44, and the first ID information and the second ID information stored in the data buffer memory unit 32 are collated. That is, it is determined whether or not the first and second ID information match. In this determination, if it is determined that the first ID information and the second ID information match, the process proceeds to step S46, a match signal is output, and the green light emitting diode is turned on in step S48. On the other hand, if it is determined that the first ID information and the second ID information do not match, the process proceeds to step S50 to turn on the red light emitting diode. If the first ID information and the second ID information do not match, no match signal is output. After performing the process of step S48 or step S50, the process returns to step S30.

As described above, in the first embodiment, the first ID information is magnetically recorded on the information card 1 and the second ID is electrically recorded.
ID information is stored, the first and second ID information are read by the card reading device 12, and a match signal is output when the contents match each other. The card reading device 12 disables reading of the second ID information until reading the magnetically recorded first ID information, and reads the second ID information after the first ID information is taken in.

Therefore, in the information card 1, different 2
Since the ID information is recorded on each of the two media, duplication becomes difficult and the leakage of secrets can be prevented. Further, since it is necessary to read the first ID information recorded in the magnetic stripe area 2 with the card reading device 12, the information card 1 is inevitably brought close to the card reading device 12. As a result, the power for transmitting the second ID information stored in the memory unit 6 can be small, and the antenna can be downsized. In addition, the first recorded on the magnetic stripe area 2 of the information card 1 from the time when the information card 1 is brought close to the card reading device 12 up to the distance at which the second ID information from the information card 1 is received by the card reading device 12. Since the ID information is read, the distance between the information card 1 and the card reading device 12 is almost eliminated,
Therefore, a small amount of power is required to operate the information card 12 to operate it.

(II) Second Embodiment In the first embodiment described above, after the first ID information and the second ID information are respectively fetched, they are collated, and if they match, a coincidence signal is output. However, this Example 2
Then, the card reader 12 registers the first ID information and the second ID information in advance, and when the fetched first ID information and second ID information match the registered information, a match signal Is output. Since the configurations of the information card 1 and the card reading device 12 are the same as those in the first embodiment, they will be replaced with FIGS.

Operation of Card Reading Device FIG. 5 is a flow chart showing the operation of the card reading device 12 of the second embodiment. First, in step S70, the control unit 1
8 supplies the read command to the 1/0 converter 24,
It is converted into a predetermined code of "1" or "0". This code information is supplied to the modulator 26. The modulator 26 modulates the signal from the oscillator 25 with the code information and supplies the modulated signal to the power amplifier 27. Then, the power-amplified modulated signal is supplied to the transmission / reception coil 28 and transmitted.

Next, the control unit 18 sets 1 in step S72.
The output of the / 0 converter 31 is captured, and it is determined in step S74 whether the 1/0 converter 31 has output the code information that is the second ID information. In this determination, if it is determined that the second ID information is not output, the process returns to step S70. On the other hand, the second ID
If it is determined that the information has been output, the process proceeds to step S76,
It is determined whether or not the second ID information is pre-registered information. The second ID acquired in this judgment
If it is determined that the information is not the information registered in advance, the process proceeds to step S88, and the red light emitting diode is turned on.
After this processing, the process returns to step S70.

On the other hand, if it is determined that the fetched second ID information is registered in advance, step S
In step 78, the output of the I / F unit 17 is fetched.
Then, in step S80, it is determined whether or not the first ID information is output. In this case, the magnetic card reader unit 15
When the first ID information recorded in the magnetic stripe area 2 of the information card 1 is read by
The waveform-shaped first ID information is output from the I / F unit 17.

In the determination at step S80, the first I
If it is determined that the D information is not output, step S78
Return to On the other hand, if it is determined that the first ID information is output, the process proceeds to step S82, and it is determined whether or not the first ID information is pre-registered information. In this determination, when it is determined that the fetched first ID information is not registered in advance, the process proceeds to step S88, and the red light emitting diode is turned on. On the other hand, when it is determined that the fetched first ID information is registered in advance, the process proceeds to step S84, a match signal is output, and the green light emitting diode is turned on in step S86.

As described above, in the second embodiment, the first ID information is magnetically recorded on the information card 1 and the second ID is electrically recorded.
ID information is stored, the first and second ID information are read by the card reading device 12, and if they are mutually registered information, a coincidence signal is output. Card reader 12
First captures the electrically stored second ID information, and if the second ID information is registered, captures the magnetically recorded first ID information. . Then, when the fetched first ID information is registered information, a coincidence signal is output.

Therefore, similarly to the first embodiment, in the information card 1, since the ID information is recorded on each of two different media, it becomes difficult to copy the information and the secret can be prevented from being leaked. Further, since it is necessary to read the first ID information recorded in the magnetic stripe area 2 with the card reading device 12, the information card 1 is inevitably brought close to the card reading device 12. As a result, the power for transmitting the second ID information stored in the memory unit 6 can be small, and the antenna can be downsized.
In addition, the first recorded on the magnetic stripe area 2 of the information card 1 from the time when the information card 1 is brought close to the card reading device 12 up to the distance at which the second ID information from the information card 1 is received by the card reading device 12. Since the ID information is read, the distance between the information card 1 and the card reading device 12 is almost eliminated, and therefore the power applied to the information card 12 to operate it can be small.

The present invention is not limited to the above embodiments, and various embodiments are possible within the scope of the object of the present invention. Specifically, the following may be done. (A) In the first embodiment, the first ID information recorded in the magnetic stripe area 2 of the information card 1 and the second ID information stored in the memory section 6 of the information card 1 have the same content,
I tried to determine if these match,
The contents may be different from each other and combined to give one meaning, and it may be determined whether or not they match the registered information when combined. By doing so, it is possible to further prevent leakage of secrets.

(B) In the first and second embodiments, the transmitting / receiving coil 4 of the information card 1 and the transmitting / receiving coil 2 of the card reading device 12 are used.
Although the transmission and reception frequencies of 8 are the same, the transmission frequencies may be different from each other. In this case, as is apparent, the transmission frequency of the information card 1 is the same as the reception frequency of the card reading device 12, and the reception frequency of the information card 1 is the same as the transmission frequency of the card reading device 12. (C) In the first embodiment, the first ID information recorded in the magnetic stripe area 2 of the information card 1 is not read until the second ID information stored in the memory section 6 of the information card 1 is read. However, the order may be reversed. That is, the second ID information stored in the memory section 6 of the information card 1 is not read until the first ID information recorded in the magnetic stripe area 2 of the information card 1 is read.

(D) In the second embodiment, the second ID information stored in the memory section 6 of the information card 1 is read, and when the second ID information matches the registered information, it is recorded in the magnetic stripe area 2 of the information card 1. Although the first ID information is read, it may be reversed. That is, the first ID information recorded in the magnetic stripe area 2 of the information card 1 is read, and when this matches the registered information, the second ID information stored in the memory section 6 of the information card 1 is read. . (E) In the first and second embodiments, the card reading device 12 reads the first ID information recorded in the magnetic stripe area 2 of the information card 1 and the second ID information stored in the memory section 6. The first and second ID information may be rewritten by the card reading device 12. This can further prevent the leakage of secrets. In this case, needless to say, in the second embodiment, the registration information is rewritten as the first and second ID information are rewritten.

[0042]

According to the present invention, the following effects can be obtained. (1) Since the magnetic recording means for magnetically recording the ID information on the information card and the transmitting means for transmitting the ID information stored in the memory are provided, it becomes difficult to make a duplicate, and the leakage of the secret is prevented. You can Further, since the ID information recorded in the magnetic recording means needs to be read by the card reading device, the information card is inevitably brought close to the card reading device. This allows the I stored in the memory
The power for transmitting the D information can be small and the antenna can be downsized. (2) When the card reading device receives the ID information of the memory transmitted from the information card, the first ID information reading means is activated and the received ID information is read by the second ID information reading means of the card reading device. Read the ID information received and read and the first ID
Since the coincidence signal is output when the ID information read by the information reading means matches, the information card is brought close to the card reading device to the distance at which the ID information from the information card is received by the card reading device. Since the ID information recorded in the magnetic recording means of the information card is read from time to time, the distance between the information card and the card reading device is almost eliminated, and therefore the power applied to the information card to operate the transmitting means. Can be small.

(3) When the ID information recorded on the magnetic recording means of the information card is read by the first ID information reading means of the card reading device, the receiving means of the card reading device is activated and transmitted from the information card. When the received ID information is received, and the received ID information and the ID information read by the first ID information reading means match, a match signal is output, so that the information card is read by the card reading device. Since the receiving means is activated after being taken in, the distance between the information card and the card reading device is eliminated, so that a small amount of power is required to operate the transmitting means of the information card.

(4) The second ID information of the memory transmitted from the information card is received by the receiving means of the card reading device, and when the second ID information matches the registered information, the first ID reading means is operated. Since the first ID information recorded in the magnetic recording means of the information card is activated and the read first ID information matches the registered information, the coincidence signal is output. Since the ID information recorded in the magnetic recording means of the information card is read from the time when the information card is brought close to the card reading device to the distance at which the ID information from the card is received by the card reading device, the information card and the card reading device are read. Since there is almost no distance between the transmitting means and the transmitting means of the information card, a small amount of power is required to operate the transmitting means of the information card.

(5) When the first ID information recorded on the magnetic recording means of the information card is read by the first ID information reading means of the card reading device, and the first ID information matches the registration information. To activate the receiving means of the card reading device to receive the second ID information transmitted from the information card,
Then, since the coincidence signal is output when the received second ID information matches the registration information, the receiving means is activated after the information card is taken into the card reading device. Since there is no distance from the reading device, a small amount of electric power is required to operate the transmitting means of the information card.
