Hello, my name is Fabian, I've been assigned to support your case.
Thank you for your interest in our products.
The reason why the PN7642 isn't able to read the iPhone is because, iPhone doesn't emulate a type 4 tag. It can emulate cards but, through a proprietary protocol.
Our Reader do support this protocol but, in order to get access it is required to contact your Distributor since this is a very restricted software.
Unfortunately, the PN7642 won't detect your iPhone if your software doesn't support ECP even if you are using a emulation of a card. i.e. Transport Card or ApplePay.
Best Regards,
Fabian
