RFID tags come in two forms, active and passive. Though both use the same RFID technology, they are different in many ways. Active tags are powered by a battery built into the tag allowing data to be communicated through long distances. Passive RFID tags are smaller and use radio waves to transfer data. To help you decide what type of RFID tag is right for your needs, we've created a chart to show the differences and similarities between active and passive tracking.
