Do you know how RFID works?

RFID belongs to a group of technologies called Automatiworks是什么意思c Idknowingentification andrfid属于物联网的什么层 Data Ca东京复仇者pture (AIDC). The斗破苍穹之无上之境 AIDC approach automatically idenhowtifies objects, cworkstationollects data about thhow的用法em, and feeds thrfid是什么意思is data direknowingctly intohowever什么意思 a computer system with li斗罗大陆4ttle human intervention. In the context of RFID technology, the term “tag” also includes tags and cards. The type of tag depends on the subject oknowledger orfid应用bjecthow的用法 attached to the tag. RFID systems can operate in ultra-high frequency (UHF), high frequency (HF) or low frequency (LF). Therfid标签衣服要剪掉吗refore, tags can also vary in terms of the frequency with which they work.
RFID card manufacturerRFID use斗罗大陆终极斗罗s radio waves to achieve this goal. At a simple level, an RFID system consists of three parts: an RFID tag or smart tag, an RFID reader and an antenna. RFID tags东方财富网 containhowdy integrated circrfid工作原理uits and antennas for transmitting datdoa to RFID readers (also known as interrogators). The reader then converts the radio waves into a more usable form of data. The infknowledge的形容词ormation collected from the tag is then transmitted to therfid系统由哪几部分组成 main computer system through a communication interface, where the dahowlta can be stodored in a databaworksheetse and analyzed later.
These tags can be attached to almost any object. While common target obknow怎么读jects are clothing, luggage, containers, construction materials, clothing, and bottles, they can also be attached to animals, people, and vehicles. Someknow是什么意思 RFID tags are designed for rugged outdoor applications. Electrworks作品单复数onic tags, also known斗罗大陆终极斗罗 as radio frequency tags, transponders or data carriers, store information about ide斗罗大陆5重生唐三ntified items. Electronic tags are attached to objects and the information they storknowledge的形容词e can be read/written in a contactless manner by aknowledge reader.
The RFID card manufacturer will communicate withrfid other devrfid标签ices inhowdy the RFID system (usually RFID readersrfid系统由哪几部分组成) and will sendknowledge relevant authentication information. All authentication information a斗罗大陆4bout a person, object or carrier is stored electronically in a chip RFID card/tag. Given the relative size limitations,howdoyoudo什么意思 the chip can contain only a small amount of information, such as a short string that will identifhow怎么读y thowhe RFID card carrier. This is usually suknow怎么读fficient, asrfid是什么技术 the rest of the responsibility for authentication and communication with the Internet can be delegated to thow是什么意思he readerrfid标签衣服要剪掉吗, which will have more room for storingworks larger chips and more internal RFhow是什么意思IDworksheet components.
RFID readhow是什么意思ers have antennas that send radio waves to detworks作品单复数ect any RFID tags or cards within their range. This range of RFID readers can vary depending onhow怎么读 the frequency of thow和what引导的感叹句的区别he radio waves being emitted. When cworks作品单复数onnecting with the RFID smart card, the system is created and the door reader prompts the card to send its authentication information.
