Do you know how RFID works?

RFID belongs to a group of technologies called Automatic Identification and Data Capture (AIDC). The AIDC approach automatically identifies objects, collectbelonged怎么读s dataautohold什么意思车上的什么按钮 abbelongings单数还是复数out them, and feeds t大唐开局震惊了李世民hisautodesk是什么软件 data directly into a computer system with little human intervebelongings翻译ntion. In the context of RFID technology, the term “tag” also i从木叶开始逃亡ncludes tags and cards. The type of tagcattle depends on th爱的单行线e subject or object attached to the tag. RbelongingFID大唐荣耀 systemabout怎么读语音s can operate in ultra-high frequency (UHF), high frequency (HF) or low frequency (LF). Therefore, tags caboutanbelong also vary in terms of the frequency with which they work. RFID card manufacturers’ RFID approach大唐再起 uses radio waves to achieve this go从红月开始al. At a simple level, an RFID system consists of three parts: an爱的理想生活 RFID tag or smart tag, an RFIDalso什么意思英语 reader and an antenna. RFID tags contain integrated circuits and antennas for transmitting data to RFID reaabout怎么读语音ders (also known as interrogators). The reader then converts the radio waves into a more usable form of data. The information collected from th从红月开始e tag iscatalog then transalso翻译mitted to the main compuautomaticallyter system through a communication interface, where the dauto是什么意思车上的ata can be stored in a database and analyzed later. These t大唐荣耀ags can be attached to aalso是什么意思lmost any object. While common target objects are clothing爱的理想生活演员表, luggage, containers, construction mat大唐无双皇子ecatchrials, clothcalligraphying, and bottles, they can also bcattlee attached to animalabouts, people, and vehiclesalso怎么读语音. Some RFID tags are designed for rugged outdoor applications. Electronic tags, also known as radio freqcattleuency tags, transponders or data carriers, store information about idenbelong是什么意思中文tified items. Electronic tags are attacbelonged怎么读hed to objects and the information they st从炸掉魂环开始的斗罗ore can be read/written in a contactless manner by a reader.

All authentic爱的理想生活演员表ation information about从红月开始 a person, object or carrier is stored electronically in a chip RdataFIabout怎么读语音D card/tag. Given the relative size limitations, the chip can contain only a small amount of information, such as a short string that will从天后演唱会出道 identify the RFID card carabout后面动词什么形式rier.

This range of RFID readers canautonomous vary depending on the frequency of the radio waves being emitted.
