Further, when the sealing is normal, the first RFID tag circuit 30 sends a normal state information to the RFID reader 10 according to the result of the reading state module circuit 60, after the vulnerable connection circuit 50 or the state module circuit 60 is destroyed or changed. The first RFID tag circuit 30 sends an abnormal state information to the RFID reader 10 according to the result of the read state module circuit 60, and there is a difference between the normal state information and the abnormal state information.

Further, a memory is disposed in the first RFID tag circuit 30, and the pairing information is set in the memory, and the pairing information is paired with the state data 70 stored in the state module circuit 60.

Example 2:

As shown in FIG. 3, the state module circuit 60 is constructed by a second RFID tag circuit 301, and the second RFID tag circuit 301 includes a second RFID tag readout interface 201 and a second state module for reading. The interface 401, the second state module reading interface 401 is connected to the first state module reading interface 40 through the fragile connection circuit 50, and the first RFID tag circuit 30 and the second RFID tag circuit 301 are respectively The two detachable portions provided in the seal are used to read the state of each other by the first RFID tag circuit 30 and the second RFID tag circuit 301, and send status information to the RFID reader 10, respectively.

Example 3: Further, as shown in FIG. 4, a state module circuit 60 is further disposed between the first RFID tag circuit 30 and the second RFID tag circuit 301, and the state module circuit 60 passes through two vulnerable connection circuits 50 respectively. It is connected to the first RFID tag circuit 30 and the second RFID tag circuit 301. The status data 70 is stored in the status module circuit 60.

Further, in the first RFID tag circuit 30 or the second RFID tag circuit 301. Alternatively, the first RFID tag circuit 30 or the second RFID tag circuit 301 sends an abnormal status message to the RFID reader 10 after the status module circuit 60 or the vulnerable connection circuit 50 is destroyed.

The invention also provides an RFID anti-counterfeiting sealing device for changing information after unpacking, wherein the RFID anti-counterfeiting sealing device for changing information after unpacking comprises a main circuit module, and the main circuit module includes a first An RFID tag circuit 30, the first RFID tag circuit 30 includes an RFID tag readout interface, wherein the first RFID tag circuit 30 is connected to a first state module read interface 40, The first state module read interface 40 is coupled to a state module circuit 60 via a fragile connection circuit 50, which stores state data.

Further, the state module circuit 60 is composed of a second RFID tag circuit 301, and the second RFID tag circuit 301 includes a second RFID tag readout interface 201 and a second state module read interface 401. The second state module reading interface 401 is connected to the first state module reading interface 40 through the fragile connection circuit 50.

Further, a first state module reading interface 40 is connected to the first RFID tag circuit 30, and the first state module reading interface 40 is connected to a state module circuit 60 through a fragile connection circuit 50. The state module circuit stores the state data 70, and the state module circuit 60 is connected to the second state module reading interface 401 in a second RFID tag circuit 301 through another fragile connection circuit. The second RFID tag A second RFID tag readout interface 201 is included in the circuit.

In the embodiment shown in FIG. 1, the first RFID tag in the first RFID tag circuit 30 The readout interface 20 will not be destroyed before and after unpacking, and the unpacking action will only destroy the vulnerable connection circuit 50 or the state module circuit 60. After unpacking, the RFID reader 10 can still be destroyed. An RFID tag readout interface 20 reads the RFID data; the first RFID tag circuit 30 reads the state data 70 in the state module circuit 60 from the first state module read interface 40 via the fragile connection circuit 50, and the RFID tag security seal The first RFID tag circuit 30 changes the RFID data sent by the first RFID tag readout interface 20 to the RFID reader 10 based on the read status data.

Figure 2 illustrates one of the simplest and most inexpensive embodiments of the state module circuit 60 of Figure 1 as part of the conductive structure of the breakaway connection circuit 50. The state data 70 of the state module circuit 60 prior to unpacking is A simple ground connection, the first state module read interface 40 is read to a low potential via the fragile connection circuit 50; after the unpacking, the easy-to-break connection circuit 50 is disconnected, and the first state module read interface 40 is read to be pulled up via the resistor R. To the high potential of V+, the first RFID tag readout interface 20 sends the corresponding RFID data to the RFID reader 10 according to different conduction states before and after unpacking.

Since the RFID reader 10 can still read data from the first RFID tag readout interface 20 in the first RFID tag circuit 30 after unpacking, the first RFID tag circuit 30 can be used to redeem the prize, or to track the flow of the article, or Check the relevant information online, or use it as proof of identity when reselling after unpacking.

Although the implementation method of Figure 2 is cheap, there is a risk that if the manufacturer who wants to fake can connect the anti-counterfeiting seal with a new easily damaged connection, the fraudulent manufacturer can recycle the anti-counterfeiting main structure for fraud. This is why most of the one-time RFID anti-counterfeiting seals must completely destroy the RFID chip. In order to solve this problem, the state data 70 is processed in pair with the RFID chip content in the first RFID tag circuit 30 of the RFID tag security seal according to FIG. 1. When the unpacking action destroys the vulnerable connection circuit 50, The first state module reading interface 40 cannot read the paired state data 70, and the RFID tag security seal first RFID tag circuit 30 sends the corresponding information when the paired state data 70 is not read. The contents of the RFID data to the RFID reader 10 can prevent the fraudulent manufacturer from using the RFID tag anti-counterfeit seal to falsify the first RFID tag circuit 30, and the status data 7 is stored in a memory, although the status data 70 can be destroyed during unpacking. This memory will increase the cost, but in this way, the RFID tag anti-counterfeit sealing of the first RFID tag circuit 30 can be safely operated after being unsealed or taken away. This method is particularly suitable for wine bottles and cigarette packages. .

Even so, when the product is bottled or canned, the bottle or other bottled or canned counterfeit manufacturer cannot recover the bottle cap or can lid, but still has the opportunity to recycle only the bottle or can body without the RFID tag. The fake RFID anti-counterfeit seal looks like the original product, further reducing the cost of fraud. Therefore, the embodiment of Fig. 3 proposes a method for solving the problem that the bottle body and the can body are taken away by the counterfeit manufacturer. In FIG. 3, when the fragile connection circuit 50 is not broken, the first state module reading interface 40 reads the state data of the second RFID tag circuit 301 through the fragile connection circuit 50, and then reads the interface from the first RFID tag. The RFID data corresponding to the undisrupted state is sent to the RFID reader 10; and when the fragile connection circuit 50 has not been destroyed, the second RFID tag circuit 301 does not send the data to the RFID reader 10.

When the fragile connection circuit 50 is destroyed during unpacking, the second RFID tag circuit 301 sends the RFID data corresponding to the corrupted state to the RFID reader 10 via the second RFID tag readout interface 201.

When the product is a bottle or a can or a box, the security cover can be divided into two parts, an inner cover and an outer cover, the first RFID tag circuit 30 is placed on the outer cover as an outer label, and the second RFID tag circuit 301 is placed as an inner label. The inner cover is closely connected with the bottle body or the can body or the box body, and cannot be completely removed. The first RFID tag circuit 30 on the outer cover and the second RFID tag circuit 301 on the bottle body or the can body or the box body are The connection circuit 50 is disconnected, and the first RFID tag circuit 30 on the outer cover can be taken after the unpacking; the inner label on the inner cover is closely connected with the bottle body, the can body and the box body, and cannot be completely removed, the second The RFID tag circuit 301 is placed over the inner cover. After breaking the connection circuit at the time of unpacking, the read data of both the inner tag and the outer tag will have The change will increase the difficulty of fraud, so that the recycled bottle body, can body and box body can no longer be used for new products, and the flow direction can be tracked.

The last problem is that if the counterfeit manufacturer can recover the paired anti-counterfeit bottle and the anti-counterfeit bottle cap, or the two sides of the cigarette wrap, it is still possible to use it for fraud. Although this probability is very low, the user must not take it. The anti-counterfeiting seal is to be redeemed, and a paired bottle/can/cap and bottle/can/box are also provided to the counterfeit manufacturer, but in order to completely prevent the problem from occurring, the embodiment of Fig. 4 provides a preferred solution. In Fig. 4, in addition to a frangible connection circuit 50 for connecting the outer cover and the inner cover, a state module circuit 60 is added, and the first RFID tag circuit 30 and the second RFID tag circuit 301 are each easily broken. The connection circuit 50 is connected to the state module circuit 60. The state module circuit 60 stores the state data 70. When the anti-counterfeit seal is produced, the state data 70 is the anti-counterfeit seal of the RFID tag and the first RFID tag circuit 30 and the second RFID. The contents of the RFID chip in the tag circuit 301 are paired, and the breakable connection circuit 50 and the like are simultaneously destroyed during unpacking. Module circuit 60, so that the RFID internal and external labels on the bottle/can/cap and the anti-counterfeit seal on the bottle/can/box can continue to work separately, even if the matched bottle/can/cap and bottle/can can be recycled at the same time The RFID anti-counterfeit label on the box body can not be used for fraud as long as the status module circuit 60 cannot be copied, thereby protecting the anti-counterfeit bottle/can/cap and the bottle/can/box from being recycled, not afraid of being faked. Use.

Even if it is not a bottle, can, or box structure, as long as it is a sealed product, the RFID tag can be divided into two parts, one part is the first RFID tag circuit 30, and the other part is the second RFID tag circuit 301, two Each of the two is connected to a state module circuit 60 via a frangible connection circuit 50, and the breakable connection circuit 50 and the state module circuit 60 can be broken by the unpacking action to achieve that the RFID on the inner and outer tags continue to work independently, but can be avoided. The danger of recycling fraud.

In this way, the two problems in the prior art that the chip may be reused and the damaged anti-counterfeit seal cannot be applied to other purposes are completely solved. The technical solution proposed by the utility model is not focused on the innovation of how to destroy the anti-counterfeit sealing, but in the system and circuit structure And the innovative changes in the way of use.

Fig. 5 is a schematic view showing another embodiment of an RFID anti-counterfeiting sealing device for changing information after unpacking according to the present invention. In order to be able to transmit multi-bit data while being easily destroyed by the unpacking action, the embodiment of FIG. 5 minimizes the number of connecting lines in the connection circuit 50, thereby adopting standard serial communication. The three-wire structure, including the ground line, is a total of four signal lines. If two-way communication is not required, the data output line can be omitted, leaving only the data input and the clock signal line and the ground line, a total of three lines.

As shown in FIG. 6, by using the signal line power supply, one power supply line can be omitted, and the number of connection lines in the connection circuit 50 can be reduced. In FIG. 6, the data line is connected to the cathode of the diode D, and the anode of the diode D. The anode is connected to the anode of the lower capacitor C to be rectified, and becomes the power source in the state module circuit 60. Since the power consumption of the state module circuit 60 can realize the logic operation in the microampere to less than one microampere, the diode D and the capacitor C can be integrated into the chip, and no additional diodes and capacitors are needed on the outside; The same effect can be achieved by taking the clock signal line without using the data line.

Adding a power line or using the power supply of Figure 6 can achieve the key purpose of this patent. It can be freely selected according to the actual packaging requirements and the process conditions of the core design and the power consumption design of the state module.

The signal line frequency is not high. The input impedance of the interface between the two sides is in the circuit of the CMOS chip. The current is very low, so the impedance of the connecting line can work normally in the range of several hundred ohms to several thousand ohms, so as to make these lines Thin, and with a material that is easily broken or torn, the purpose of breaking the connection can be achieved. The commonly used ones in the industry are printed toner wire connections or silver glue wires, which are printed on easily tearable paper. Above, the port can be crimped to other boards and easily broken.

As for the chip to be broken when it is unpacked, the chip can be placed on a thin, flexible paper printed circuit board. This is an inexpensive structure that has often been used in the toy industry to fix the chip on the printed circuit paper. , lay the line and then apply glue to protect against moisture and simple protection, as long as the structure is matched with so-called The V-cut of the V-cut, the chip that is aligned with the memory state data 70, can be destroyed together with the chip storing the state data 70 at the time of unpacking. Even if there is no V gap, as long as the unpacking must be forced, it is also very easy to completely destroy the chip structure of the storage state data 70.

Figure 7 shows the flow of the RFID anti-counterfeiting device for changing information after unpacking. The RFID reader 10 sends RFID energy to the first RFID tag circuit 30. When the first RFID tag circuit 30 receives sufficient energy, it performs power on reset. Step 700 of power-on reset, and then performing step 702 of reading the status module data, performing step 704 of determining whether the status is broken according to the read status module data, and when the status module is not destroyed, the first RFID tag circuit 30 performs Step 706 of sending status module integrity information; when the status module has been corrupted, the first RFID tag circuit 30 performs a step 708 of sending status module corrupted information.

Figure 8 shows the program flow of the second RFID tag circuit. The RFID reader 10 sends RFID energy to the second RFID tag circuit 301. When the second RFID tag circuit 301 receives sufficient energy, it performs a power on reset power-on reset step 800, and then performs a step 802 of reading the status module data, the second RFID. The tag circuit 301 performs a step 804 of determining whether the state is broken or not based on the read state data 70. When the state module 60 is not destroyed, the second RFID tag circuit 301 performs a non-reactive step 806, and does not send the RFID data; When the 60 has been corrupted, the second RFID tag circuit 301 performs a step 808 of sending information that the status module 60 is corrupted.

As described above, the RFID anti-counterfeiting sealing method for changing information after unpacking according to the present invention includes a process of providing a first RFID tag circuit 30 on the sealing, activating and utilizing the first RFID tag circuit 30, by the first state The module read interface 40 reads the state of a state module circuit 60 through a fragile connection circuit 50 or reads the state data 70 stored in the state module circuit 60, and then reads the RFID according to the result of the read state module circuit 60. The device 10 sends a status message.

Further, a second RFID tag circuit 301 is further provided, and the second RFID tag circuit 301 is activated and utilized, and the second state module reading interface 401 reads a state module circuit 60 through a fragile connection circuit 50. State or read the state module circuit The status data 70 stored in 60 is then sent a status message to the RFID reader 10 based on the results of the read status module circuit 60.

The existing disposable anti-counterfeiting seals have been designed in many different ways. As long as people familiar with the anti-counterfeiting sealing mechanism design can easily develop their own methods of destruction, there are many references on the Internet and in the patent library, such as the front. The proposed method of destruction in several disposable RFID tags can be used as a reference, and the method of how to destroy the structure of the RFID circuit is not the focus of the present invention/invention.

The utility model/invention solution is that the anti-counterfeit sealing device changes the circuit structure when unsealing, and only some of the circuits are separated or destroyed after unsealing, and the RFID chip and the antenna can still work normally, but the information when the RFID is read after unpacking It is different from the information before it was destroyed.

The RFID read value on the anti-counterfeit seal is related to the content of the isolated or damaged part, so the chip that gets the anti-counterfeit seal can not duplicate the complete RFID read data, thus solving the problem that the RFID chip is recycled and fraudulent. The RFID tag on the anti-counterfeit seal after unpacking can still work, can be used for redemption, or as a follow-up identification, or to track the anti-counterfeit seal of the product.

Although the above example is based on RFID anti-counterfeiting, the published content can be applied to various RFID anti-counterfeiting products and other RFID commercial fields.

The above embodiments are merely illustrative and not limiting. Any equivalent modifications or alterations of the present invention are intended to be included within the scope of the appended claims.
