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.
Why is RFID tags used instead of bar codes use to tag goods?
Both RFID tags and barcodes are used to tag products, but RFID has many advantages. An RFID tag can be read at a distance. That helps with inventorying stock, and also helps to catch shoplifters. Retailers have a problem with shoplifters putting an expensive item in a cheap item's box; because the RFID tag would be on the product itself it wouldn't matter what box it was in.
What type of RFID tag contains its own power source?
Usually RFID tags would get the power from the reader.
How easy is it to buy RFID tags?
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.
How big is a rfid tag?
RFID size is normally determined by the size and configuration of the antenna, not the actual RFID integrated circuit. Hitachi sells chips with low-performance internal antennas that are the size of a table salt crystal. Most RFID tags are between 20 and 100 mm in length/width and very thin.
How do you deactivate a low or high frequency passive or semi-passive or active rfid tag in the human body?
A powerful electro-magnetic field pulse can kill most electronic devices. Physical removal is effective. EPC standard RFID's can be killed via command from a tag reader.

Are passive RFID tags read-write or write once only?
Passive RFID tags can be both read/write or write-once. They can also be bought pre-written.
What is the answer for a device that tracks movement?
An RFID tag is a microchip combined with an antenna in a compact package; the packaging is structured to allow the RFID tag to be attached to an object to be tracked.
What type of RFID tag contains its own power source?
Usually RFID tags would get the power from the reader.
What is the purpose of an RFID reader?
An RFID Reader is a device that decodes RFID tags, sometimes called smart labels, via a wireless device. The RFID tag contains a microchip which this device reads and processes.
What does RFID use to communicate with a tag attached to an object in computers?
radio Software, Rfid board & antenna Whatever you place on the board with rfid tag with specail software you can read, write and erase the tags. Mostly bar codes for books or dvds.

Who invented the RFID technologies?
In 1945 Léon Theremin invented an espionage tool for the Soviet Union which retransmitted incident radio waves with audio information. Sound waves vibrated a diaphragm which slightly altered the shape of the resonator, which modulated the reflected radio frequency. Even though this device was a covert listening device, not an identification tag, it is considered a predecessor of RFID technology.
What technology uses radio signals to communicate with a tag placed in or attached to an object an animal or a person?
The technology that uses radio signals to communicate with a tag placed in or attached to an object, animal, or person is called RFID (radio-frequency identification). RFID tags or chips are attached to objects, animals, or people, and RFID readers can send and receive signals from these tags using radio frequency (RF) technology. The RFID reader sends a signal to the tag, which responds with the stored data. 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, animal tracking, and electronic payment systems.
