Description
Technical field
The present invention relates to RFID chip and RFID tag, the RFID mark for commodity under different survival states is particularly belonged to
The random coded field of label.
Background technique
When some specialities or important goods dispatch from the factory, we usually need to make some special random volumes to them
Code, is in a certain special state to represent it, and after this product enters another use state, we wish outer again
Boundary cannot easily obtain this coding, in order to avoid product is misled into also in original survival state.For example it is 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 generate 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 (other than manufacturer's database)
Be difficult to be resumed either, this some high added values or high price commodity it is anti-fake in, to preventing from utilizing old packaging
Or used electronic tag fraud just has critically important meaning.

When being bonded again after external component is separated with the particular combination face, make the electrically conductive geometry on particular combination face
Figure is randomly bonded again, then interactive switch interface circuit unit is resurveyed to one group of status bit message；
After the formation of foregoing original state position information, if application system reads the shape of the electronic tag
When state position information is not original state position information, the application system will assert foregoing external component and particular combination face
Once separated.
Further, the electronic tag is encapsulated using flip chip mounting process；Electrically conductive contact on the particular combination face
Directly it is made of the chip bonding pad of the interactive switch port in the RFID chip with interactive switch port；The chip bonding pad is constituted
Topological node；There is the metallic pattern for topological node electrical connection by particular design when upside-down mounting；It is described to be used for topological node
The metallic pattern of electrical connection is in flip-chip because the random site of the metallic pattern being bonded with machining error, chip misses
Difference and the conducting resinl being bonded for upside-down mounting are bonded error at random, and the topological node is made to generate random topology connection relationship；It is described
The electronic tag of the soft encapsulation of upside-down mounting has the topology status information generated at random.
Further, the electronic tag with random topology state of the reverse installation process encapsulation is to attach the soft mark used
Label；After the completion of Tag Packaging, then interactive switch interface circuit unit collects one group of initial topology status information；It is attached in label
After use, when label tears off from attaching object, the initial topology state of the label can be destroyed, the interactive switch of chip
Interface circuit unit cannot collect initial topology status information.
Further, the RFID electronic label is the NFC tags of 13.56MHZ frequency.It or is 800/900MHz's
The electronic tag of VHF frequency.Or the microwave section electronic tag for 2.45GHz.
The solution have the advantages that unquestionable, by the variation of status bit message can the accurate discrimination true and false, prevent
It is mixed the spurious with the genuine by low-quality goods, is of great significance to maintenance social equity order and value.The solution of the present invention stability
By force, high reliablity, and relatively easily realize, can widely it be applied in anti-counterfeit field.
