What are semipassive RFID tags designed to do?

  1. Send out data without any power

  2. Send out data and use energy from the reader to extend their range

  3. Only store data without transmitting it

  4. Function only when near a power source

The correct answer is: Send out data and use energy from the reader to extend their range

Semipassive RFID tags are designed to utilize a combination of stored power and the energy received from the RFID reader to function. They contain a battery that powers the microchip and enables them to send data back to the reader, but they also can harness energy from the reader's signal to improve communication range and efficiency. This dual capability allows semipassive RFID tags to extend their operating range compared to passive tags, which solely rely on the reader's energy for operation. The option about sending out data without any power does not apply, as semipassive tags do require a power source, even if it's supplemental from the reader. The choice that suggests they only store data fails to recognize their active data transmission capability. Lastly, stating that they function only when near a power source inaccurately portrays their ability to operate independently while still using a battery for certain tasks.
