Emulation of an NFC-A document

[Cosmo_Ciano]

I am a QA (quality assurance) of an app on which you need to identify yourself to register.
For registration testing purposes I was trying to emulate ID cards (with their owners’ permission, of course).
My questions are as follows:

1. I can only emulate the first part (pre-auth) is this correct? after the Authorization process the flipper let me see the data inside of the document
2. When I emulate the app it does not recognize nfc and on the flipper I see log R: 00 (i’ve checked also with other apps)
3. When I save the card the ATQA and SAK values change is this normal? When reading they were ATQA:00 00 and SAK: 00

It depends of chip in the ID card. I don’t even know which country it is.

For me, smartphone can’t recognize the Flipper’s emulation of Classic. I think it’s an instance of known problem - timing out responses. Magic cards are usual workaround.

They should not and they don’t, for me.
