What is the difference between RFID and SmartTAG?

April 11,2023.

RFID (Radio Frequency Identification) and SmartTAG are both technologies used for tracking and identifying objects, but they differ in several ways.

RFID is a technology that uses radio waves to read and capture data stored on a tag or label attached to an object. RFID tags can be either passive or active, with passive RFID tags relying on the energy emitted by the reader to power the chip and transmit the data stored on it, while active RFID tags have their own power source and can transmit data over greater distances.

SmartTAG, on the other hand, is a specific type of RFID technology used for electronic toll collection (ETC) systems. It uses a passive RFID tag embedded in a small device called a transponder that is attached to a vehicle's windshield. When the vehicle passes through an ETC lane, the transponder is read by a reader and the toll is automatically deducted from the driver's account.

In summary, RFID is a more general technology that can be used for a variety of applications, while SmartTAG is a specific application of RFID technology used for electronic toll collection.
