Tamper device for active RFID electronic tag

Abstract

The invention provides a tamper device for an active RFID electronic tag. The active RFID electronic tag comprises a shell, a power supply module, a control module, a wireless radio frequency module and a radio frequency antenna coil, wherein the power supply module, the control module, the wireless radio frequency module and the radio frequency antenna coil are arranged in the shell and connected in sequence; the power supply module, the control module and the wireless radio frequency module are all welded to a PCB, and the radio frequency antenna coil is etched on the PCB. The tamper device comprises a control switch and a boosting module, wherein the power supply module, the control switch, the boosting module and the wireless radio frequency module are connected in series in sequence; the control switch will be triggered and connected with the boosting module and the wireless radio frequency module when the active RFID electronic tag is dismantled illegally, so the wireless radio frequency module can be broken down instantly. As a result, the tag is destroyed permanently, and a user or an unauthorized person can be effectively prevented from applying the active RFID electronic tag to other usages after dismantling the tag privately.

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...

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
