Core NFC (nfc iso 7816) IEC_7816

Hi Guys, Is it possible to add an additional information upon emulating the iPhone using Apple Pay / Passkit? I want to broadcast an information with custom data to the reader using core NFC as well. In addition, If its allowed to use nfc ios7816 as a low level communication, which part of IEC_7816 will allow us to modify / do? Thanks to the genius guys out there.

There is a hidden field for user specific information inside a pass which can be read from iOS apps.

But I’m not sure if its contents are among the data made available via NFC.
