      Isn’t RFID compatible with NFC antennas? There’s plenty of apps on F-Droid to interact with RFID tags using NFC.

      Same thing for IRDA, some manufacturers still do include it in their devices.

        RFID compatible with NFC antennas

        Only the HF RFID stuff. There is also LF and UHF RFID. FZ has an LF RFID antenna.

        “NFC tags are a subcategory of HF RFID technology. All NFC tags are HF RFID tags, but not all HF RFID tags are NFC tags. NFC operates in a very specific subset of the high-frequency range —13.56 MHz— and have very different use cases and implementation considerations from other RFID categories”

        Same thing for IRDA

        IrDA isn’t the same as IR. There were some phones with an actual IR blaster built in but most were IrDA.
