RFID tags are composed of several components—a micro-chip, a substrate (e.g., Mylar or plastic coating), and an antenna, which is attached to the micro-chip. The primary difference between active and passive RFID tags is that active tags incorporate a built-in power supply, while passive tags use the power from the electromagnetic wave from the RFID reader to send its data to the reader. Apart from this primary distinction, you’ll find more in-depth differences in the table below. Active Tags Passive Tags Power Powered by internal source (e.g., battery or solar
NFC is an acronym for Near Field Communication. NFC is a fairly recent ‘labeling’ for a subset of RFID (Radio Frequency Identification) for short-range, wireless protocols. It’s most commonly used for close-range applications (hence the “near field”). NFC has some features that distinguish it from other forms of RFID, such as the capacity for bidirectional peer-to-peer communication. To learn more about NFC, click here.
