Hi Remco.
Apple was very restrictive with NFC, I think not even allowing non-Apple apps to use NFC until very recently.
If you get a cheap second hand android and you can trigger almost anything from setting alarms, toggle Wifi, pre-typed text message, launching apps.
I understand you prefer solutions for your current hardware, but in a kind way, I want to point out that at the moment it’s like bringing one shoe to a running race, the footwear, not the fitness of the athlete, will let the system down.
