Its basic principle is to use the transmission characteristics of radio frequency signal and space coupling or radar reflection to realize automatic identification of identified objects. The space coupling can be inductive or electromagnetic coupling.

基于RFID技术的RFID系统通常包括电子标签与阅读器两部分。其中的电子标签也称为RFID标签，是RFID系统的数据载体，通常包括天线与专用芯片，专用芯片也称为微处理器。依据供电方式的不同，电子标签可以分为有源电子标签(Active tag)、无源电子标签(Passivetag)和半无源电子标签(Semi-passive tag)。其中，有源电子标签内装有电池，无源射频标签没有内装电池，半无源电子标签部分依靠内装电池工作。依据工作频率的不同，电子标签可分为低频电子标签、高频电子标签、超高频电子标签与微波电子标签。依据封装形式的不同，电子标签又可分为信用卡标签、线形标签、纸状标签、玻璃管标签、圆形标签与特殊用途的异形标签等。An RFID system based on RFID technology usually includes two parts: an electronic tag and a reader. Among them, the electronic tag is also called RFID tag, which is the data carrier of the RFID system, and usually includes an antenna and a dedicated chip, and the dedicated chip is also called a microprocessor. According to different power supply methods, electronic tags can be divided into active electronic tags (Active tag), passive electronic tags (Passive tag) and semi-passive electronic tags (Semi-passive tag). Among them, the active electronic tag is equipped with a battery, the passive radio frequency tag does not have a built-in battery, and the semi-passive electronic tag partially relies on a built-in battery to work. According to different operating frequencies, electronic tags can be divided into low-frequency electronic tags, high-frequency electronic tags, UHF electronic tags and microwave electronic tags. According to different packaging forms, electronic tags can be divided into credit card tags, linear tags, paper tags, glass tube tags, round tags and special-purpose special-shaped tags.

目前，RFID系统已经逐渐应用于物流、航空、邮政、交通、票务、金融、军事、医疗保险、跟踪、矿井、设备和资产管理等领域，通过对人或设备等特定目标配戴的RFID标签的监管，实现对人或设备等特定目标的监管。目前可以根据各种场合应用需求，使用有源、无源、半无源RFID标签来进行资产管理。At present, RFID systems have been gradually used in logistics, aviation, postal services, transportation, ticketing, finance, military, medical insurance, tracking, mines, equipment and asset management, etc., through RFID tags worn by specific targets such as people or equipment Supervision, to achieve the supervision of a specific target such as a person or a device.
