Re: [android-developers] Re: NFC Secure Element

Hi All, 

Recently I have tried with another Card reader , I got this message. 

MIFARE 4K card on reader 

ATR : 3B 8F 80 01 80 4F 0C A0 00 00 03 06 03 00 02 00 00 00 00 69  

00 02 --> Shows the Mifare 4K 

Earlier with another Card I was getting --> 3B 8A 80 01 00 31 C1 73 C8 40 00 00 90 00 90 and I read in this group that it is for emulated Card Smart MX.

I wanted to know 

(1) Can the  two Card readers produce different ATR for the same card?If yes , Why so?

(2) Can I get the notification or any type of logs when the read /write transaction is happening.or do I have to put the LOG messages , preferably in the NFC framework files.

(3) Is it possible to READ(not Write ) the SE element(i.e Mifare 4k ) memory Area using the APDU(I think this is same as what others have mentioned in this group)

Rgds,

Saurabh
