Hello,

I know that one of the operating modes of NFC is the "Card Emulation"
Mode. It allows the NFC phone to be seen as a "Smart Card". I've tried
Samsung Galaxy S II and it can be seen as a ISO14443 tag, but his UID
is random. Why?
Is it also possible to access the secure element fo the NFC phone by
an external NFC device?
Now there are some NFC phones called "SIM - Based". Why? I've read
that it is because the SIM card (UICC) of the phone is NFC-enabled.
What it means? it emulates a smart card? it is accessible by an
external NFC device.

Thank you very much in advance.
Best Regards.
Eliseo
