Topic: Using LibNfc to read/write NDEF tag on Android

Hi All ,
I'm a newbie in NFC.
I need to implement read & write NDEF tag functionality for NXP PN547 chip on Android.
Is there an nfc library release, which supports the  NXP PN547 chip.
If yes, is there any documentation or examples, describing
how I can access the chip via the library directly?
Thanks in advance.
Regards, Svetlana
