TRF7970A: How to differentiate between NFC Mobile data vs NFC Card data

Part Number: TRF7970A

Hello,

We have designed an NFC reader. We would now like to validate the PAN received from the NFC data.

It is possible to accomplish this using NFC chip on the card as our reader receives the card data.

But how should we distinguish between NFC data received from mobile phones. The PAN here is encoded.

1) Is there a way to figure out if the data received is from Mobile or physical Card??

2) How to validate the Mobile NFC data

Thank you for your help
