Abstract

The invention relates to the technical field of radio frequency identification, specifically a radio-frequency identification tag and a control method therefore. The identification tag comprises an antenna or a coil, a radio-frequency simulation front end, a digital baseband circuit, and a storage unit. The radio-frequency simulation front end comprises a rectification circuit, a reference voltage-stabilizing circuit, a modulation circuit, a demodulation circuit, a resetting circuit, a clock circuit, and a pin interconnection state detection circuit. Through the polling of all pins of the pin interconnection state detection circuit, the pin interconnection state information is obtained, and stored in the storage unit. A reader writes in and reads the pin interconnection state information in the storage unit through employing a self-defined command. The identification tag will detect the current pin interconnection state information at a tag circulating link after power-on, and stores the pin interconnection state information in a register. The pin interconnection state information is compared with delivery pin interconnection state information stored in a nonvolatile memory. If the pin interconnection state information is consistent with the delivery pin interconnection state information stored in the nonvolatile memory, a product is determined to be an original commodity, or else the product is determined to be forged. The identification tag is very high in safety, and has an anti-fake function.

Description

technical field

[0001] The invention relates to the technical field of radio frequency identification, in particular to a radio frequency identification tag and a control method thereof. Background technique

[0002] Radio Frequency Identification (RFID, Radio Frequency Identification) technology is a non-contact automatic identification technology, which can realize the purposes of identification, tracking, positioning and management of items. Radio frequency identification technology can be widely used in many fields such as industrial automation, commercial automation, transportation control management, anti-counterfeiting, etc., and has attracted widespread attention. The most basic RFID system consists of an RFID reader and an RFID tag, and the RFID tag consists of a tag antenna and a tag chip.

[0003] Commodity anti-counterfeiting systems based on radio frequency identification technology have been widely used. Install RFID tags on the products, and consumers can us...
