Strong shielding type confidential electronic tag and using method thereof

Abstract

The invention belongs to the technical field of electronic tags, and particularly relates to a strong shielding type confidential electronic tag and a using method. The strong shielding type confidential electronic tag comprises a tag body, a display screen, an induction lamp and the like. A central processing unit, a two-dimensional code generation module, a radio frequency module, an infrared induction module, a voltage stabilizer, an electronic battery module and the like are arranged in the label body. Through the induction function of the infrared induction module, the single-chip microcomputer is arranged on the display screen, so that the working time of the display screen is 8-10 s, and the possibility of false awakening of the electronic tag is prevented; through signal connectionbetween the mobile terminal and the electronic tag, confirmation of the network cloud and generation of the two-dimensional code through the two-dimensional code generation module, signal connectioncan be successful, code scanning is passed, and the mobile terminal is in signal connection with the central processing unit through the radio frequency module. Therefore, the electronic tag and the application method thereof achieve the effects of high confidentiality and strong shielding.

Description

technical field [0001] The invention belongs to the technical field of electronic tags, in particular to a strong shielding confidential electronic tag and a usage method. Background technique [0002] RFID is a technology that automatically identifies target objects and obtains data through radio frequency signals. The RFID system may be composed of electronic tags and readers; wherein, the electronic tags include two types: active electronic tags and passive electronic tags. The above-mentioned active electronic tag is usually in a dormant state. When the active electronic tag receives a wake-up signal from the reader, the active electronic tag will turn from the dormant state to the working state; when the active electronic tag and the reader are completed When data interaction or interaction error occurs, it will re-enter the dormant state. [0003] The active electronic tags in the prior art are flawed both in terms of confidentiality and false wake-up signal identifi...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the defects in the active electronic tags in the prior art, whether it is confidentiality or false wake-up signal recognition, which leads to the end of the service life, and the use of active electronic tags is directly connected to the signal, resulting in Due to the disadvantage that the important information in the active electronic tag will be leaked, the present invention provides a strong shielding type confidential electronic tag with strong shielding, strong confidentiality and long service life and its use method
