RFID (Radio-Frequency Identification) is a technology that uses radio waves to communicate between a reader and a passive RFID tag. The tag, which is often a small sticker or tag that can be affixed to an object, contains an integrated circuit that stores and processes information. The reader, which is a device that emits radio waves, can read the information stored on the tag and send it to a computer or other device for processing.

There are many potential uses for RFID technology, including:

• Inventory tracking: RFID tags can be used to track the movement of goods within a warehouse or store. This can help businesses keep better track of their inventory and improve efficiency.
• Supply Chain Management: RFID tags can be used to track the movement of goods from the manufacturer to the retailer, providing real-time visibility on where products are in the supply chain and improving logistics.
• Access Control: RFID tags can be used to control access to restricted areas, such as a building or a secure room.
• Asset tracking: RFID tags can be used to track the location and usage of valuable assets such as vehicles, equipment, and tools.
• Livestock tracking: RFID tags can be used to track the location and health of livestock, making it easier to manage and care for the animals.
• Payment systems: RFID tags can be used in payment systems, such as contactless payment cards and mobile payments.
• Automatic identification, tracking of people and vehicles, monitoring of environmental conditions, and so on.
