Referring to fig. 1 to 7, the present invention provides a technical solution:
an anti-theft RFID card is a card 1 with RFID tag, as shown in FIG. 1, the card 1 contains an antenna coil L 12, a double chip including a chip I3 and a chip II 4, and a single-switch double-control switch S 15。
The utility model discloses a card 1 with RFID label is close behind RFID reader 6, and RFID reader 6's antenna L2Emitting an alternating magnetic field, an antenna coil L in the card 11Feeling of 2The antenna coil L is measured by the alternating magnetic field emitted by the RFID reader 612 at the antenna coil L due to electromagnetic induction effect 12, an alternating current is generated, and the energy carried by the alternating current is first transferred from the first capacitor C1After storing energy, the first capacitor C1Releasing the energy to form an alternating current, and passing the alternating current through a diode D1And a second capacitor C2After the composed rectifying and filtering circuit is rectified and filtered, a direct current driving chip is formed, and the chip comprises a chip I3 and a chip II 4. Antenna coil L 12 for inducing a first radio wave signal with first information transmitted by the RFID reader 6 to form a first signal current with first information, and transmitting the first signal current to the chip, wherein the chip responds to a second signal current with second information according to memory data in the chip 12 and by an antenna coil L 12 form a second electric wave signal according to the second signal current and return the second electric wave signal to the rfid reader 6.
At the antenna coil L12 a single-open double-control switch S is arranged between the chip 15, by single-open double-control switch S 15 to control whether the RFID tag is activated or not. When the function of the wireless radio frequency identification tag of the card 1 is needed, the single-switch double-control switch S is pressed15, starting the function of the radio frequency identification tag, receiving the first electric wave signal and returning the second electric wave signal, and switching on the double control switch S by a single switch 15 adjusting the state of the connection circuit to prevent others from reading the data stored in the card with a conforming RFID reader.
The present embodiment uses a single-switch double-control switch S 15 the on state of the position controls whether the circuit of the wireless radio frequency identification label is really information is started or not, thus achieving the function of data theft prevention.
The following is a detailed description:
when the card 1 is an entrance guard card, a bus card, a canteen consumption card, an IC card and the like. As shown in fig. 1 and 4, is used for double-opening and double-closing of a single switchOff S 15 when stirring position 1, be about to the arch 9 of the body of rod 7 stir draw-in groove I10 department and press in draw-in groove I10, the circuit that chip I3 located is put through and is formed the return circuit, when radio frequency identification reader 6 was close to when reading this moment, chip I3 can be with memory data passback to radio frequency identification reader 6, discerns reader 6 through radio frequency and can read detailed card information in the card 1 promptly. At this time, in order to prevent a lawbreaker from stealing the information of the chip by using the rfid reader 6 of the same specification when the card 1 is on the body of the user, it can be defined that the information in the chip i 3 is not the true information of the user, that is, the chip i 3 is set as a "pseudo card", and even if the lawbreaker acquires the card information of the chip i 3 in the card 1, the true information of the user is not leaked. In the single-switch double-control switch S1The state of 5 being toggled to position 1 is suitable for situations where the user card 1 is mounted on a body without using the card 1.
When the card 1 is actually used, as shown in fig. 2 and 5, the user will turn on the single-switch and the double-switch S 15 when stirring position 2, be about to the body of rod 7 and take out in draw-in groove I10, then stir draw-in groove II 11 department and press in draw-in groove II 11, the circuit that chip II 4 was located is put through and is formed the return circuit, when confirming that safe wireless radio frequency identification reader 6 is close to when reading this moment, chip II 4 can be with memory data passback to wireless radio frequency identification reader 6, through wireless radio frequency identification reader 6 can read the card information of detail in the card 1 promptly. The implanted information is stored on the chip II 4, namely the real information of the user, and when the safe radio frequency identification reader 6 is confirmed to read the information, the bulge 9 is pressed in the card slot I10 again. Of course, which of the chip I3 and the chip II 4 stores the implanted user real information or stores the user non-real information as a 'pseudo card' can be flexibly set.
In the utility model, the through groove 12 comprises two same clamping grooves, namely a clamping groove I10 and a clamping groove II 11, as shown in fig. 6, when the rod body 7 is positioned in any one of the clamping groove I10 and the clamping groove II 11, the rod body 7 is clamped in the through groove 12, and the upper surface of the rod body 7 is flush with the surface of the card 1; single-switch double-control switch S 15, an elastic rod body 7 is adopted,so as to rotate the rod body 7 by taking the pin 8 as a rotating shaft; the protrusion 9 and the rod body 7 can be integrated, and conductive aluminum and copper layers or other conductive metal layers are embedded on the lower surface of the protrusion 9, so that the circuit of the chip I3/the chip II 4 is correspondingly connected by pressing the clamping groove I10/the clamping groove II 11. Because current radio frequency card is card 1 itself generally gentle promptly, can certain degree buckle, buckle a little and can take out the body of rod 7 from the draw-in groove, certainly also can be as shown in fig. 7, make the thickness of the body of rod 7 slightly be greater than the degree of depth of logical groove 12 for the body of rod 7 can be slightly outstanding outside card 1, and the user of being convenient for is held between the fingers the body of rod 7 from the draw-in groove that corresponds and is taken out. For convenience of the card slot, that is, the chip i 3/chip ii 4 corresponding to the card slot i 10/card slot ii 11, the marks may be marked beside the card slot i 10 and the card slot ii 11, for example, writing an arabic numeral "1" beside the card slot i 10 and writing an arabic numeral "2" beside the card slot ii 11 may correspond to positions 1 and 2 in fig. 1, so that a user may clearly know the circuit connection state of the chip i 3/chip ii 4.
The utility model discloses, can go into the pilot lamp according to the circuit cluster that actual use condition located at I3 of chip II 4, the pilot lamp HL of fig. 1, fig. 2 promptly1Indicator lamp HL2The indicating lamp is embedded in one side of the card 1, so that the indicating lamp HL can be conveniently used for reading the card normally1The state of (1) knows the completion of the circuit of the card 1.
The utility model discloses, bury two sets of chips underground in card 1, one of them chip storage user' S true card information, another storage disguised card information is as "pseudo-card", through the two accuse switches S of single division 15 adjusting the state of connecting the chip and the circuit, when the chip is used, the user card information can be connected, and when the chip is not used, the disguised card information can be connected to be used as a 'fake card', so that the user real data or card information stored in the card can be prevented from being read by other people and lawbreakers by a conforming radio frequency identification reader.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
