The RFID is powered by its own antenna. When in the presence of a pulating magnetic field, the antenna generates a signal that can power up the RFID, causing it to generate its code on top of that field.

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.
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.
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.
Would this RFID be cheaper than Lojack, and still work inside buildings and underground car garages? If your answer is yes, then my answer is yes.

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.
Electrical energy is the type of kinetic energy that powers a cell phone. When you charge your phone, electrical energy is stored in the battery and converted to power the device when in use.
In a mobile device, the battery (chemical energy) converts into electrical energy to power the device. When the phone is being used, the electrical energy powers the various components of the phone, such as the screen, processor, and antenna.
Yes, aluminum foil can effectively block RFID scanners because it acts as a barrier to the radio waves used by the scanners to communicate with RFID tags. Placing an RFID card or device in an aluminum foil pouch can prevent it from being scanned.
circuits are made by connecting wires to an electrical resource and the electricity travels through and powers your electric device.
To effectively block RFID signals using aluminum foil, wrap the RFID card or device in multiple layers of foil to create a barrier that prevents the signals from being transmitted or received. Make sure the foil completely covers the card or device to block the signals effectively.
