Typically by running an internal clock.
Radio-frequency identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders.
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.
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.
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.
RFID tags are incredibly easy to purchase. There are many websites and businesses devoted to the increasingly popular RFID technology. A simple search will show you plenty of places that will work with you to create an RFID tag.

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.
Radio Frequency Identity Tags.
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.
A block diagram of the RFID or radio frequency identification can be found online at places like TI.com and Colorado.edu.

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.
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

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.
