In contrast to passive RFID, active solutions typically include a power supply in the tag, which is in most cases a battery. The main difference when compared to passive solutions is the extended communication distance that can be achieved with active RFID. A potential drawback is that the battery capacity limits the lifetime of the tags. Microchip solves this issue by combining LF RFID and UHF technology within one chip, thus extending the battery lifetime to a maximum. Applications requiring large read/write distances are basically tracking-related systems such as: assets, containers, and industrial automation but also include people or animals. Since the tag incorporates an MCU, sensor signals can also be read and transmitted.
