Description
Technical field
The present invention relates to RFID chip and RFID tag, the RFID marks under different survival states for commodity are particularly belonged to
The random coded field of label.
Background technology
When some specialities or important goods dispatch from the factory, we usually need to make some special random volumes to them
Code, a certain special state is in represent it, and after this product enters another use state, we wish outer again
Boundary can not easily obtain this coding, in order to avoid product is misled into also in original survival state.Such as led in commodity counterfeit prevention
Domain, we have been desirable to such a random coded scheme, before commodity are not gated on consumption, we can produce it is a kind of completely with
The state encoding of machine, and after commodity are activated consumption, this state encoding is not just deposited again at extraneous (beyond manufacturer's database)
Either be difficult to be resumed, this some high added values or high price commodity it is false proof in, to preventing from utilizing old packaging
Or used electronic tag fraud just has critically important meaning.
The content of the invention
Present invention aim to address random coded problem of the commodity under different conditions, to prevent counterfeit and shoddy goods
Production.
To realize that the technical scheme that the object of the invention is used is such, a kind of carrier state inputs the double-side electronic of contact

The interactive switch input port of the RFID chip by the electrically conductive geometric figure on electronic tag and components A, B it is electrically conductive
Geometric figure formation galvanic circle, so as to collect one group of state encoding.
When components A, B fit together at random with two particular combination faces of the electronic tag respectively, make these special
The electrically conductive geometric figure determined on faying face is randomly fitted, then interactive switch input port collects one group of original state position
Information.
When being fitted again after components A, B are separated with the particular combination face of the electronic tag respectively, make these specific knots
Electrically conductive geometric figure on conjunction face is randomly fitted again, then interactive switch input port is resurveyed to one group of mode bit
Information.
After the information formation of foregoing original state position, if application system reads the shape of the electronic tag
State position information be not original state position information when, the application system will assert as previously described the particular combination face of electronic tag with
Components A or/and part B were once separated.
Further, after the calculation control unit read status information, status information is led to by radio-frequency interface circuit unit
Radio-frequency antenna is crossed to be sent out.
Or, when there is storage information in the memory cell that RFID chip is carried, the calculation control unit reading state
After information, the storage information is processed according to status information, the information after processing is led to by radio-frequency interface circuit unit
Radio-frequency antenna is crossed to be sent out.
Further, two particular combination faces of the electronic tag are by two kinds of particular combination face random combines, i.e., two spies
It is particular combination face I to determine faying face, or two particular combination faces are particular combination face II, also or one of face is

Embodiment 5：
Referring to Figure 14, reality of the application system on commodity of the double-side electronic label of carrier state input contact is originally embodied as
With.Components A, B and electronic tag are arranged on commodity to examine whether commodity are used.The part B is to be placed on bottle
Circular gasket at mouthful, its particular combination is face-up.The components A is arranged on the inner surface of lid, and its particular combination is face-down.
The radio frequency identification tag package is between them.When encapsulating the commodity, components A, B particular combination face respectively with electronic tag two
Individual particular combination face is fitted at random, and resulting status bit message is referred to as factory state bit combination coding, this shape that dispatches from the factory
State bit combination coding is sent in the application system of correlation (i.e. each functional part interaction of RFID).
Assuming that the corresponding electrical potential information of this factory state bit combination coding is " 11+110 ", then this commodity is in quilt
This state will be always maintained at before the use of Kaifeng, and calculation control unit will select the message reflection of this assembly coding to reading and writing
On device.So consumer need to only firmly believe the information that read write line shows when buying commodity and can distinguish the true from the false.If this commodity was once
Used through being opened, but unauthorized person mutually reuses this commodity packaging and is an incompetent person or a person unequal to his task.When commodity are repacked again,
New mode bit assembly coding then occurs, this new mode bit assembly coding generally with corresponding to " 11+110 "
Factory state bit combination coding be it is different (can be identical although there is part probability, belong to less in application demand
Probability, disclosure satisfy that utilization in practice).So the state of read write line can reflect this commodity and initial mismatch, then consumer
It should not just select to buy this counterfeit or inferior quality goods.
Meanwhile, if the shelf-life for the commodity being used for is 1 year, the time of the original state position information produced during packing is made
To produce the date, it is assumed that this original state is that information is " 01+010 ", then calculation control unit will handle this information simultaneously
Relevant information recorded in RFID application systems.Among in this year, not recorded the status bit message of this commodity has
Any change.If after 1 year being equally the state of " 01+010 ", then calculation control unit can be locked to deposit according to control strategy
Storage unit, by abnormal information reflection to read write line, shows that this commodity is expired.
