What Is a Passive RFID Tag?
A passive RFID tag is a batteryless tag typically used in smaller-scale operations and tracking systems. Because a passive tag has no internal power source, it is instead powered by the energy transmitted from an RFID scanner.
Key points to remember regarding passive RFID tags include:
-
They have no internal power source and are powered by a reader
-
They have a lower signal range than active RFID tags
-
Each one has a longer life expectancy than active RFID tags

How Passive RFID Tags Work
A passive RFID system consists of a reader, an antenna, and a passive tag. As the tag has no battery or power source, it consists of two components: an antenna and a microchip or integrated circuit (IC).
