In the embodiment shown in fig. 1, it is all can be not destroyed that a RFID label in the one RFID tag circuit 30 is read interface 20 before sealing off and after sealing off, seal off action and only can destroy destructible connecting circuit 50 or block of state circuit 60, after sealing off, RFID reader 10 still can be read interface 20 by a RFID label and read RFID data; The one RFID tag circuit 30 is read interface 40 through the state information 70 in destructible connecting circuit 50 reading state modular circuits 60 by the first block of state wherein, the RFID data that RFID label anti-counterfeit sealing the one RFID tag circuit 30 changes a RFID label and reads interface 20 and pass out to RFID reader 10 according to read different state information.
Fig. 2 has represented a kind of embodiment method of simple cheap, it is exactly the part using the block of state circuit 60 in Fig. 1 as the conducting structure of destructible connecting circuit 50, before opening, the state information 70 of block of state circuit 60 is simple grounding connections, and the first block of state is read interface 40 and read electronegative potential through destructible connecting circuit 50; After sealing off, destructible connecting circuit 50 has disconnected, the first block of state is read interface 40 and has just been read the noble potential of drawing high V+ via resistance R, according to before sealing off and different conducting states afterwards, a RFID label is read interface 20 and is sent corresponding RFID data to RFID reader 10.
Because RFID reader 10 still can be read interface 20 by the RFID label in a RFID tag circuit 30 and read data after sealing off, so can take a RFID tag circuit 30 to remove prize, or following the trail of article flows to, or online inquiry relevent information, or while reselling again after opening as proof of identification.
Although the implementation method of Fig. 2 is cheap, but there is a risk, if want exactly the manufacturer faking anti-fake sealing and new easy to be a destroyed connection can be connected, the manufacturer faking so just can reclaim anti-fake sealing main structure and play tricks, this reason that namely most of disposable RFID anti-fake sealing all will thoroughly destroy RFID chip.In order to address this problem, according to Fig. 1 state information 70 when the production anti-fake sealing be with RFID label anti-counterfeit sealing the one RFID tag circuit 30 in the pairing of RFID chip content process, when having sealed off action breaks after destructible connecting circuit 50, the first block of state is read interface 40 and is read less than the state information 70 having matched, the corresponding RFID data content that RFID label anti-counterfeit sealing the one RFID tag circuit 30 is just sent while reading less than pairing state information 70 arrives RFID reader 10, as long as energy collapse state data 70 in the time sealing off, just can prevent that the manufacturer faking from utilizing RFID label anti-counterfeit sealing the one RFID tag circuit 30 to fake, state information 7 is stored in a storer, although increasing this storer can raise the cost, but so, RFID label anti-counterfeit sealing the one RFID tag circuit 30 that allows that just can be relieved still can be worked after opening, or the prize of being taken away, this method is for bottle and cigarette packets particularly suitable.
Even so, when kinds of goods are while being bottled or canned, although bottle or other bottled, canned fraud manufacturers cannot reclaim bottle cap or cover, but still have an opportunity only the to reclaim body or the can body that there is no RFID label, allow and do not have the fake products of correct RFID anti-fake sealing to appear to former factory goods, also further reduce fraud cost.Therefore the embodiment of Fig. 3 has proposed to solve body, can body by the manufacturer that the fakes method of utilizing of taking away.In Fig. 3, do not have when destroyed in destructible connecting circuit 50, after the state information that reads the 2nd RFID tag circuit 301 through destructible connecting circuit 50 by the first block of state reading interface 40, reading interface 20 by a RFID label will not have corresponding RFID data under destroyed state to pass out to RFID reader 10; And also do not have when destroyed in destructible connecting circuit 50, the 2nd RFID tag circuit 301 can not sent data to RFID reader 10.
After destroyed in the time that destructible connecting circuit 50 is being sealed off, the 2nd RFID tag circuit 301, will read interface 201 via the 2nd RFID label and send the corresponding RFID data of destroyed rear state to RFID reader 10.
In the time that kinds of goods are bottle or jar or box, false proof lid can be divided and make inner cap and enclosing cover two parts, the one RFID tag circuit 30 is placed on enclosing cover as outer label, the 2nd RFID tag circuit 301 is placed on inner cap with body or can body or box body and closely links as interior label, cannot completely take off, the RFID tag circuit 30 covering outward and body or can body or box the 2nd RFID tag circuit 301 are with it connected with a destructible connecting circuit 50, can take the RFID tag circuit 30 covering remove prize after opening outward; The interior label inside covering and body, can body, box body closely link, and cannot completely take off, and the 2nd RFID tag circuit 301 is just placed on inner cap.Destroy the two connected circuit in the time sealing off after, the two the data of reading of interior label and outer label all can be had some change separately, increases fraud difficulty, and body, can body, the box body that makes to reclaim cannot turn again and do new product and use, and can follow the trail of its flow direction.
Last problem is if fraud manufacturer can be recovered to the false proof body and the anti-fake bottle lid that have matched simultaneously, or cigarette packets is sealed the both sides of having matched, still be likely used to fake, although this probability is very low, must end user not take anti-fake sealing to remove prize, but also to provide bottle/tank/lid of having matched and bottle/tank/box body to fraud manufacturer, but in order thoroughly to prevent the generation of problem, the embodiment of Fig. 4 provides a preferred solution, in Fig. 4, be connected with inner cap at original enclosing cover outside a destructible connecting circuit 50 of use and increased again a block of state circuit 60, the one RFID tag circuit 30 and the 2nd RFID tag circuit 301 are connected to this block of state circuit 60 via a destructible connecting circuit 50 separately, in described block of state circuit 60, store state information 70, in the time of production anti-fake sealing, state information 70 is that the RFID chip content sealing in a RFID tag circuit 30 and the 2nd RFID tag circuit 301 with RFID label anti-counterfeit is that pairing is processed, destructible connecting circuit 50 and block of state circuit 60 when opening, have been destroyed simultaneously, so the inside and outside label of the RFID of the anti-fake sealing on bottle/tank/lid and bottle/tank/box can work on separately, enable to reclaim the bottle/tank/lid and the bottle/tank/box RFID antifalsification label with it that have matched simultaneously, as long as cannot replication status modular circuit 60, also cannot make for faking, that has protected anti-fake bottle/tank/lid and bottle/tank/box body with this is not recovered use simultaneously, be not afraid of by fraud one's share of expenses for a joint undertaking and utilize.
Even if be not the structure of bottle, tank, box, as long as there being the kinds of goods of sealing, RFID label can be divided into two parts, some is a RFID tag circuit 30, some is the 2nd RFID tag circuit 301, both are connected to a block of state circuit 60 via a destructible connecting circuit 50 separately, the RFID that just can utilize opening action breaks destructible connecting circuit 50 and block of state circuit 60 to reach on inside and outside label continues to work independently, but can avoid being recovered again the danger of fraud.
Thoroughly solved thus prior art chips may be repeated to utilize and destroy after anti-fake sealing cannot be applied to the two large problems of other purposes.The technical scheme emphasis that the present invention proposes not is the innovation how destroying above the mode of anti-fake sealing, but changes at system and circuit structure and the innovation above use-pattern.
