Argon is going away, what do we do about NFC needs?
I think I misunderstood what the argon is capable of. Can it not read NFC tags?
Particle Gen 3 devices (Argon, Boron, B Series SoM, and TrackerSoM) only support emulating an NFC tag. They cannot locate or communicate with tags themselves, or support protocols such as for NFC payments.
The Argon, Boron, and Tracker SoM are themselves an NFC tag, which can be read from a mobile device, for example. They cannot read tags.
You can add an NFC tag reader. The PN532 chipset is popular and connects by UART. Adafruit has a breakout board that should work with the the P2, Photon 2, and Argon.
