SUMMARY
Smartphones cannot natively transmit or receive 125KHz RFID signals due to the absence of compatible antennas. While NFC technology operates at 13.56MHz, the required hardware for 125KHz communication is not present in standard smartphones. Users can, however, utilize external 125KHz RFID reader/writer devices connected via USB to Android phones for this purpose.
