The long range sensors would require a battery for the RFID to broadcast. That's why they say Magic Bands are only good for a few years (for the long range stuff). The KTTWC doesn't have a battery.
Passive RFID chips (without a battery) can still be read by long-range readers. When the reader "scans", it sends out a microwave signal that temporarily powers the chip and its antenna, allowing it to broadcast a signal back to the reader.
