Trying to use simtrace with 4FF NFC/SIM cards

Hi all,

Just to update, I found something interesting, the Single Wire Protocol:
NFC applications on the UICC can communicate to the NFC chip using the SWP
interface. Reading on GSMA docs, I found the ETSI TS 102 613 "UICC -
Contactless Front-end (CLF) Interface". So looks like is not about 3GPP,
but ETSI standards. Also very interesting the GSMA "Requirements for Single
Wire Protocol NFC Handsets":
http://www.gsma.com/digitalcommerce/wp-content/uploads/2012/03/gsmarequirementsforswpnfchandsetsv4.pdf

I continue trying to identify why SCR3310 and simtrace aren't able to read
this SIM cards (UICC). Reading simtrace AT91SAM datasheet, it just states
"ISO7816, T0 or T1 protocols for interfacing with smart cards", while
SCR3310 v2 technical specifications are;
-T=1, T=0 protocol support
-ISO 7816 Class A, B and C SmartCard
-and CT-API (through wrapper on top of PC/SC)

I will continue analyzing the ATR for this SIM cards.

Regards,
Pedro
