What is RFID in IoT?

Updated on March 28, 2026
Radio Frequency Identification – or RFID – is used to automatically identify an object and capturing data about that object that has been stored in a small microchip tag and attached to the object. The RFID tag has a built-in antenna that communicates to a scanning device that reads the data remotely.
What is RFID and how it works?
The RFID reader is a network-connected device that can be portable or permanently attached. It uses radio waves to transmit signals that activate the tag. Once activated, the tag sends a wave back to the antenna, where it is translated into data. The transponder is in the RFID tag itself.What is difference between RFID and IoT?
RFID and NFC are based on the same technologies, and IoT is based on other core technologies. RFID - Radio Frequency Identification – is a wireless (contactless) communication technology for communication between a tag and a reader. RFID is most often used with passive tags over a few meters' range.What are the applications of RFID?
Here are the main RFID applications you can find in your daily life
- Traceability in the supply chain.
- Logistics and inventories in the retail industry.
- Security control and jewelry.
- Cosmetics and medicines.
- Control of disposals and tools in hospitals.
- Libraries.
- Files and archives.
- Aviation baggage control.
What role does RFID play in an IoT environment?
These capabilities make the foundation for building an IoT system. In other words, the function of RFID technology in IoT is to connect objects into a network and make them create and send data. Not only status data, if we are talking about IoT and RFID of the new generation.What is RFID? How RFID works? RFID Explained in Detail
What is RFID and its advantages?
RFID technology automates data collection and vastly reduces human effort and error. RFID supports tag reading with no line-of-sight or item-by-item scans required. RFID readers can read multiple RFID tags simultaneously, offering increases in efficiency.Is RFID a sensor?
Radio Frequency Identification (RFID) sensors, integrating the features of Wireless Information and Power Transfer (WIPT), object identification and energy efficient sensing capabilities, have been considered a new paradigm of sensing and communication for the futuristic information systems.What is the range of RFID?
High Frequency RFID is very common, and operates in a frequency range from 3 to 30 MHz. The read distance ranges from 10 centimeters to 1 meter. The majority of HF RFID devices function at 13.56 MHz, with moderate radio interference sensitivity.What are types of RFID?
Each RFID type can be either active (powered), passive (un-powered) or semi-passive (battery-assisted).
- Low-frequency (LF) RFID tags: 30 KHz to 300 KHz. ...
- Ultra-high-frequency (UHF) RFID tags: 300 MHz to 3GHz. ...
- Active, passive and semi-passive RFID tags.
Does RFID need battery?
Active RFID tags possess their own power source – an internal battery that enables them to have extremely long read ranges as well as large memory banks. Typically, active RFID tags are powered by a battery that will last between 3 - 5 years, but when the battery fails, the active tag will need to be replaced.Which type of antenna is used in RFID?
MTI-MT-262006 AntennaIn the middle we have a standard panel antenna which is the most common type of RFID antenna. This specific one is the MTI MT-262006 Panel Antenna, a long-range UHF RFID antenna with a high gain of 9 dBic.
