RFID (Radio Frequency Identification) technology can be used to track and identify objects or people wirelessly using radio waves. However, RFID by itself doesn't provide specific location information like GPS does.
RFID systems typically consist of three main components: RFID tags, RFID readers, and a backend database or system to manage the data collected by the readers. When an RFID tag passes within range of an RFID reader, the reader sends out a radio signal that activates the tag. The tag then transmits its unique identifier back to the reader, which can be used to identify the tagged object or person.

While RFID can't provide precise location information like GPS, it can be used in conjunction with other technologies to approximate location. For example, RFID readers strategically placed throughout a facility or environment can detect when RFID-tagged items or people pass by, allowing for a rough estimate of their location based on which reader received the tag's signal. This approach is often used for asset tracking, inventory management, access control, and similar applications where knowing the general location of tagged items or individuals is sufficient.
