Active NFC anti-counterfeiting chip with tampering dynamic detection function

Abstract

The invention provides an active NFC anti-counterfeiting chip with a tamper dynamic detection function, the active NFC anti-counterfeiting chip comprises an NFC signal processing unit and an anti-tamper control unit, the NFC signal processing unit comprises a CPU and an NFC baseband, a memory and a power supply module which are connected with the CPU, and an external pin connected with an externalantenna; the anti-tamper control unit comprises an anti-tamper control circuit, an anti-tamper detection pin and a power input pin; the tamper-proof detection pin is internally connected with a tamper-proof control circuit, and is externally connected with a tamper-proof detection component; and the power input pin is externally connected with a battery, and is internally connected with an anti-tamper control circuit and provides electric energy for the anti-tamper control circuit. The commodity authenticity can be verified and commodity tracing work can be carried out through the commodity related information stored in the NFC anti-counterfeiting chip, the chip can be effectively prevented from being transferred and reused through the anti-tamper control circuit of the chip, the cost ofthe adopted method is low, and the requirements for commodity anti-counterfeiting and tracing can be 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...
