RFID Journal Glossary
- When used to refer to an RFID transponder, the term "active" means a transponder has a power source. This is usually a battery, but energy can also be captured from light via photovoltaic cells or other sources. An active tag can, therefore, broadcast its own signal, like a cell phone. Because an active tag has its own source of power to broadcast a signal, it has a longer read range than most passive tags.
