Digital data are stored in RFID tags and acquired by a reader using a radio wave in a technique known as Radio Frequency Identification (RFID). This system also includes a radio transponder, a radio receiver, and a transmitter. When a nearby Radio Frequency Identification reader device sends an electromagnetic interrogation pulse, the tag transmits digital data, often the identifying inventory number, back to the reader. Use this number to keep track of inventories. Technology is known as RFID or Radio Frequency Identification (RFID) Radio frequency identification (RFID) is a technology that uses an RFID tag to identify, monitor, and manage items and people in real time. RFID has been considered as the next promising technology for positioning purposes because of its widespread usage in the vehicle assembly sector, warehouse management, and supply chain network. This research investigated the possibility of employing passive RFID tags for indoor positioning and object recognition to offer real-time information for monitoring movement as opposed to standard active and expensive alternatives. An RFID reader transmits electromagnetic energy, which powers passive RFID tags that have no internal power source. Access control, file tracking, race timing, supply chain management, and smart labeling are just a few of the many uses for passive RFID tags. Passive RFID systems are more cost-effective for many sectors because of the reduced cost per tag. RFID readers provide a signal to passive tags in order to activate them. Energy is transferred to an antenna, which turns it into an RF wave and transmits it into the red zone. The RFID tag’s internal antenna receives energy from the RF waves after the tag has been scanned inside the red zone. passive RFID tags have no internal power source, thus they are referred to as RFID inlays. The energy transfers from the tag’s antenna to the IC, which powers the chip that creates the signal that is sent to the RF system. Inlays and hard tags are the two most common forms of passive RFID tags available on the market. a precise positioning system that can track the movement and location of people and commodities in real-time, enabling Location-Based Services to operate more effectively (LBS). Passive tags rather than active ones are used to provide a low-cost interior positioning solution for a large number of products. The position of a passive tag is automatically registered in the database. A grid would be used to divide the experiment area evenly into equal-sized cells. At each of the four corners of the chosen space, RFID readers will be deployed. The interrogation range of an RFID reader is defined as the greatest distance at which the reader can identify a tag. Radio-frequency identification (RFID) readers will initially identify a passive RFID tag when an item is put in a cell. When a passive tag gets a signal from the reader, it creates a signal in response. RFID readers record the RSSI intensities they receive.
