RFID Tag Chip: The Micro Powerhouse Behind Contactless Identification
An RFID Tag Chip is the core integrated circuit embedded within an RFID (Radio Frequency Identification) tag, responsible for storing, processing, and transmitting data to RFID readers via radio waves. These chips are critical components enabling seamless communication in applications ranging from retail inventory and logistics to toll collection and livestock tracking.
🧩 What Is an RFID Tag Chip? An RFID tag chip is a silicon-based microchip that stores a unique identifier (UID) and other programmable information. When energized by an RFID reader’s signal, the chip modulates and transmits its data wirelessly. Depending on the tag type, these chips can be passive, active, or semi-passive.
