RFID (radio frequency identification) is a form of wireless communication that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person. How does RFID work?

Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter.

射频识别系统 是一种非接触式的 自动识别 系统，它通过射频无线信号自动识别目标对象，并获取相关数据，由 电子标签 、 读写器 和计算机 网络构成。 射频识别系统以电子标签来标识物体，电子标签通过 无线电波 与读写器进行 数据交换，读写器可将主机的读写命令传送到电子标签，再把电子标签返回的 数据传送 到主机，主机的数据交换与 管理系统 负责完成电子标签数据信息的存储、管理和控制。

RFID is an acronym for Radio Frequency Identification which means RFID is the wireless, non-contact use of radio frequency waves to transfer data and identify objects, animals, or humans. RFID systems are usually comprised of an RFID reader, RFID tags, and antennas.

What Is an RFID System? RFID System is an abbreviation of Radio Frequency Identification System. It is an "Identification system using wireless communication" that enables transferring data between "RF Tags (or Data Carriers)" that are held by men or attached to objects and "Antenna (or Reader/Writers)".

RFID (radio-frequency identification) is a method of wireless communication that uses electromagnetic waves to identify and track tags attached to objects. RFID is used across industries, typically to track the location and movement of objects, such as items in a supermarket or components in a factory assembly line.
