What is the RFID?
Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders.
What does RFID active tags do?
RFID tags can be used to track down almost any item, from automobiles to cell phones. It is basically a tracking device to be used to find out its location.
Is RFID part of IT?
Yes, RFID both assists and is overseen by IT. RFID (Radio Frequency Identification chips) is a part of tracking assets including those of IT. It has become important in keeping track of the location and movement of physical equipment. The major contribution for RFID has been for the supply chain system, where RFID complements the DBMS (DataBase Management System) in the efficient acquisition and use of high-priority equipment.
On an average how many times you can use RFID tags?
The type of RFID tag you are referring to is likely a passive device. It gets read by stimulating it with a certain RF frequency and then looks for a unique return. Hence the tag life is essentially forever.
What is the use of transmitter in rfid based attendance system?
In an RFID-based attendance system, the transmitter, often referred to as the RFID reader or scanner, emits radio frequency signals to communicate with RFID tags attached to students or employees. When a tag comes within range, it responds by transmitting its unique identifier back to the reader. This interaction allows the system to record attendance automatically, streamlining the process and reducing the chances of human error. Overall, the transmitter plays a crucial role in facilitating real-time data collection for attendance tracking.

What type of antenna used in rfid?
All types... depending on frequency and application. Lower frequency RFID's are typically near field and use inductive antenna designs, higher frequency ones use far-field designs. Low frequency RFID's like the TIRIS pet ID's use coils of wound wire. HF type RFID's like MiFARE use simple planar loop antenna designs. Most VHF RFID's use dipole and modified dipole designs with reflector elements. UHF and microwave RFID's frequently use patch and slot antenna designs.
What is mean by RFID tags?
Radio Frequency Identity Tags.
What does RFID stands for?
RFID (radio-frequency identification) is a technology that uses radio waves to communicate between devices. RFID tags or chips are attached to objects, and RFID readers can send and receive signals from these tags. This allows for identification, tracking, and data transfer between the tagged objects and the reader. RFID is commonly used in applications such as supply chain management, asset tracking, and electronic payment systems.
Block dia of rfid?
A block diagram of the RFID or radio frequency identification can be found online at places like TI.com and Colorado.edu.
What does RFID active tags do?
RFID tags can be used to track down almost any item, from automobiles to cell phones. It is basically a tracking device to be used to find out its location.
What are the best tools for performing radio frequency identification?
The tools for performing Radio Frequency Identification (RFID) would be a two-way radio transmitter-receiver and a magnetic field that powers and reads RFID's at a short distance.
What is capacitive?
It is device that will sense the environment in a form of capacitor changes. Usually an oscillator will sense this change and change frequency accordingly
What technology ended the need for brand readers?
Radio Frequency Identification (RFID) chips.
Is smart card of delhi metro is a example of RFID?
yes, it is a RFID based system uses iso 14443 standard i.e; 13.56mhz radio frequency for NFC
What is capacitive transducer?
It is device that will sense the environment in a form of capacitor changes. Usually an oscillator will sense this change and change frequency accordingly
Is RFID a technique that uses Infra-Red signals to track and identify things?
No -- the RF in RFID means radio frequency, ~900 MHz maximum. The infrared spectrum ranges from 1 THz (= 1,000,000 MHz) and up -- a big difference in frequency.
