Hello Michael Xie,
Sure, you can read NTAG 424 with an iPhone. However, please take into account that:
- iPhones with iOS 12 can only read NDEF-formatted tags.
- iPhones can only perform read operations on tags, so you cannot format your tag with NDEF using an iPhone.
Here you can find more information about the NDEF structure and encoding requirements for iOS and Android.
To configure and test tags, I can recommend you our TagXplorer software.
I hope this information helps. Please let us know if you have any doubts or concerns and we will be glad to assist you.
Best regards
Javier
