Passive NFC anti-counterfeiting chip for realizing tamper-proof detection by detecting network resistance

Abstract

The invention provides a passive NFC anti-counterfeiting chip capable of realizing tamper-proofing detection by detecting network resistance. The NFC anti-counterfeiting device comprises an NFC signal processing unit and an anti-tamper control unit, the NFC signal processing unit is an NFC anti-counterfeiting chip and comprises a CPU, an NFC baseband, a memory and a power supply module which are connected with the CPU, and an external pin connected with an external antenna; the tamper-proofing control unit comprises a tamper-proofing control circuit and a tamper-proofing detection pin, the tamper-proofing detection pin is connected with an external tamper-proofing detection network, and the tamper-proofing detection network is made of fragile conductor materials. The circuit of the NFC chip tampering detection network is not used for communication, wiring covering packages can be designed at will according to needs, and comprehensive protection on commodity packages is guaranteed. According to the method disclosed by the invention, the NFC anti-counterfeiting chip cannot be reused once being disassembled, so that the requirements of commodity anti-counterfeiting and tracing are effectively met.

Description

technical field [0001] The invention relates to the field of commodity anti-counterfeiting and traceability, in particular to an NFC anti-counterfeiting chip which realizes the anti-tampering detection function through an activatable power source, and can be used for commodity anti-counterfeiting and traceability. Background technique [0002] Near field communication, NFC (Near Field Communication) technology, evolved from the integration of non-contact radio frequency identification (RFID) and interconnection technology. By integrating the functions of inductive card reader, inductive card and point-to-point communication on a single chip, mobile terminals are used to realize applications such as mobile payment, electronic ticketing, access control, mobile identification, and anti-counterfeiting. [0003] In recent years, NFC chips have been widely used in packaging box technology. The addition of NFC makes the packaging box more user-friendly, makes human-computer interac...
