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 .
Radio-frequency identification (RFID) – Technology using electromagnetic fields to read data stored in tags embedded in other items. Wi-Fi – Technology for local area networking–based on the IEEE 802.11 standard, where devices may communicate through a shared access point or directly between individual devices.
The technology acts as a base in automated data collection, identification, and analysis systems worldwide. RFID has found its importance in a wide range of markets, including livestock identification and Automated Vehicle Identification (AVI) systems because of its capability to track moving objects. These automated wireless AIDC systems are ...
The physical layer of RTLS technology is often radio frequency (RF) communication. Some systems use optical (usually infrared ) or acoustic (usually ultrasound ) technology with, or in place of RF, RTLS tags.
As with proximity card technology, NFC uses inductive coupling between two nearby loop antennas effectively forming an air-core transformer. Because the distances involved are tiny compared to the wavelength of electromagnetic radiation (radio waves) of that frequency (about 22 metres), the interaction is described as near field.
ISO/IEC 29143 "Information technology — Automatic Identification and Data Capture Technique — Air Interface specification for Mobile RFID interrogator" [4] is the first standard to be developed for Mobile RFID. [citation needed]
The clipped tag is a radio frequency identification (RFID) tag designed to enhance consumer privacy.RFID is an identification technology in which information stored in semiconductor chips contained in RFID tags is communicated by means of radio waves to RFID readers.
Narrowband Internet of things (NB-IoT) is a low-power wide-area network (LPWAN) radio technology standard developed by 3GPP for cellular network devices and services. [1] [2] The specification was frozen in 3GPP Release 13 (LTE Advanced Pro), in June 2016. [3] Other 3GPP IoT technologies include eMTC (enhanced Machine-Type Communication) and EC ...
