Hello,
I have read your requirement carefully.
I am a NFC expert have rich experiences of 3 years.
I have developed various NFC apps for Android and iPhone, POS, Attendance system, Access Control, School management system, etc.
I am very familiar in MIFAIR classic NFC tags, such as MIFAIR Ultralight EV1, C, NTAG 213, 215, 216, etc.
For your project, I have one question.
In iOS, it's only possible to read and write NDEF data from/to NFC tags.
I hope to discuss more detail via PM.
Thanks and regards,
Peng
