Sub-ghz
"allowing it to receive and send radio frequencies between 300 and 928 MHz. These switches, radio locks, wireless doorbells, remote controls, barriers, gates, smart lighting, "
RFID
" including plastic cards, key fobs, tags, wristbands, and animal microchips."
Infrared
" that use infrared light (IR) such as TVs, air conditioners, or audio devices. It can learn and save infrared remote controls or use its own Universal remotes"
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” https://www.resourcelabel.com/resources/comparing-different-types-of-rfid-tags/
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.
It has hardware that most cell phones don’t have.

It also has an iButton reader.
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.

The Galaxy Note 3 has a IR blaster.
There are a few modern phones with it as well but it’s not common. https://www.androidauthority.com/phones-with-ir-blaster-858845/
okay, so what are practical things flipper zero can do that phones with NFC antennas and IR blasters can’t?
It’s a learning tool, it also has gpio pins and a long lasting battery.
