An anti-dismantlement device for active rfid electronic tags

Abstract

The invention provides an anti-disassembly device for an active RFID electronic tag. The active RFID electronic tag includes a housing and a power supply module, a control module, a wireless radio frequency module and a radio frequency antenna coil arranged in the housing and connected in sequence, and the power supply The module, the control module, and the radio frequency module are all welded on the PCB board, and the radio frequency antenna coil is etched on the PCB board; The radio frequency modules are sequentially connected in series; the control switch will be triggered when the active RFID electronic tag is illegally removed to connect the booster module and the radio frequency module, so as to instantly break down the radio frequency module. As a result, the label is permanently damaged, which can effectively prevent users or illegal personnel from removing it privately and using it in other ways.

Description

technical field [0001] The invention relates to an anti-disassembly device of an active RFID electronic tag. Background technique [0002] Active tags require a power module to supply the power required by the internal chip to generate external signals. It has a longer reading distance and can accommodate a larger storage capacity, which can be used to store information transmitted by the reader. Generally, the power supply module and the active tag need to be soldered on the PCB (printed circuit board). Among them such as figure 1 As shown, the power supply module 1' is a battery, the control module 2' is a single-chip microcomputer, the radio frequency module 3' is an active RFID tag chip, and they are all welded on the PCB5', and the RF antenna coil 4' is etched on the PCB5'. [0003] Nowadays, electronic tags have been widely used in vehicle management, fishing boat management, warehouse management and other industries. However, the existing electronic tags are only pa...

AI Technical Summary

Problems solved by technology

None of these methods can essentially achieve the effect of anti-dismantlement, and there is a risk of being used again

After the user or unscrupulous person removes the tag, the tag is used on other target objects, which has the problem that the information of the active tag is different from the information of the actual target object, which brings inconvenience to the application management of the active tag and also There are certain security risks
