In 413DNA , The CC file INITIALIZED content is
'000F20010000FF0406E104008000000000000000000000000000000000000000'

As explained in http://apps4android.org/nfc-specifications/NFCForum-TS-Type-4-Tag_2.0.pdf 

position 14 and 15 defined the read and write access.

 

00h NDEF file read access condition; read access without any security

00h NDEF file write access condition; write access without any security

 

Then , If I want to set NDEF file read access another just like 90 , or ff. but none of them useful. 

How can I make the NDEF file private? or read before authorization?
