Do cell phones have RFID?

Excuse me, could you please clarify something for me? I've been wondering, do modern cell phones typically incorporate RFID technology? I understand RFID, or Radio Frequency Identification, is used for various purposes like tracking inventory and managing access control, but I'm not sure if it's a common feature in smartphones. Could you elaborate on whether cell phones have RFID capabilities, and if so, how they might utilize this technology? Thank you for your time.
