PN7462 - Mifare - NfcCcid sample

Hello,

 

I am looking for another way to detect that mifare card isn't in rf field. 

At NfcCcid sample somebody implements phExNFCCcid_Check_Presence_L3A_Card which "restart" card. So every loop (Clif task) mifare card is restarted.

 

In my opinion this is wrong solution.  I have problems commands in separates CCID APDU commands like "Restore" / "Transfer". Every CCID command - NFC reader restarts card. Additionally I see that somebody handle this problem in Read/Write block by write extra Auth command every Read/Write command.
