Problems solved by technology

There is also an anti-counterfeiting method of "circuit destruction". For example, the Chinese invention patent "Method of Destroying RFID Chips in Bottle Caps Using the Principle of Electrostatic Breakdown" (201210037777.6) discloses a method that directly destroys RFID chips by electrostatic breakdown. It solves the problem that the above-mentioned RFID chips can be recycled
However, once the RFID chip is destroyed, the information inside cannot be read out at all, which will cause inconvenience in some occasions. For example, the first verification is carried out at the seller. Cannot perform secondary verification by themselves

Embodiment Construction

[0011] see figure 1 .

[0012] The RFID anti-counterfeiting method provided by the invention comprises the following steps:

[0013] Detect whether the electrostatic breakdown device is broken down, and then package the detection result into the RFID signal as a part of the content of the RFID transmission signal. At this time, the RFID transmission signal contains the detection result and the pre-stored information from the storage unit.

[0014] The present invention also provides an RFID anti-counterfeiting chip, which includes a processing unit, a storage unit, and an RFID wireless transmitting unit, and is characterized in that it also includes an electrostatic breakdown unit, and the electrostatic breakdown unit includes an electrostatic breakdown device and an electrostatic breakdown unit. A detection module connected with the device, the detection module is connected with the processor unit.

[0015] Specifically, the present invention adds an electrostatic breakdown...

Abstract

An RFID anti-counterfeiting method and a chip relate to RFID technology. The method of the present invention includes the following steps: detecting whether the electrostatic breakdown device is broken down, and then packaging the detection result into the RFID signal as a part of the content of the RFID transmission signal. At this time, the RFID transmission signal contains the detection result and the information from the storage unit pre-stored information. The invention enables the chip to change the internal state through electrostatic breakdown without damage. After the electrostatic breakdown occurs, it can ensure that the chip cannot be recycled, and it can also ensure that the original traceability information can be read correctly.

Description

technical field [0001] The present invention relates to RFID technology. Background technique [0002] RFID technology, that is, radio frequency identification technology, is a non-contact automatic identification technology. Its basic principle is to use the transmission characteristics of radio frequency signals and space coupling (inductive or electromagnetic coupling) or radar reflection to realize automatic identification of identified objects. At present, RFID chips have begun to be used for anti-counterfeiting of items, such as anti-counterfeiting of high-end liquor. In order to prevent counterfeiters from recycling RFID anti-counterfeiting labels, the RFID tags are usually destroyed at the right time by using anti-tampering and fragile technology, but the RFID chip can still be recycled after taking out the label in theory, which is a kind of "mechanical destruction". "The way of anti-counterfeiting. There is also an anti-counterfeiting method of "circuit destructi...
