An RFID chip refers to the integrated circuit (IC) component of an RFID tag or RFID transponder. This chip stores electronically encoded information and communicates wirelessly with an RFID reader or scanner when activated by radio waves. RFID chips come in various forms and configurations, depending on the specific application requirements. They typically consist of a microprocessor, memory storage, and an antenna for transmitting and receiving data. RFID chips can be passive, meaning they do not have an internal power source and rely on energy harvested from the RFID reader's radio waves for operation, or active, with an internal power source such as a battery. Passive RFID chips are commonly used in applications such as inventory management, access control, and asset tracking, while active RFID chips are suitable for applications requiring longer read ranges or real-time tracking capabilities. RFID chips play a crucial role in enabling the functionality of RFID technology across a wide range of industries and applications.
