I have a client who asked me to create an app that reads nfc data, but this data needs to come from a built in iPhone nfc tag, so the app will read through nfc the SECOND device info.
my question is, does the iPhone has a built in nfc tag? if so, can it share any device info?
iPhones do not have a "built-in" NFC tag that can transmit arbitrary data.
Neither can an app emulate a NFC tag with arbitrary info about the device.
Phone-to-phone NFC based communications are only available in a limited fashion, for example in the case of Tap to Pay on iPhone.
If your use case is not about passing payment information, this would not be available for your app.
