Hi Harry,
Im quite new to NFC, but I'm just wondering if emulation could possibly
be done by bypassing the SE altogether and instead say simulating a peer
to peer mode in order to create a tunnel through which an app could
perform secure operations etc?

don't get the intent when I send APDUs but that may be a problem
with my libnfc setup. When I have a IsoPcdA activity in the foreground

Hi Nikolay,
Maybe Doug can give some more hints on how to properly use IsoPcd?
Does he hang around here :)
I don't know, but I had BCC'd him on that message, so here is what he wrote:

Hi Nikolay,
Since you wrote the paper on this, any hints on how to activate software CE
in CyanogneMod? Looking at the code, the app should get a notification for
a IsoPcdA tag and be able to transceive() with it, but I don't get this when
sending reset, select etc. with an external NFC
Thanks for responding. See comments inline.

Hi Shailen,
I see that you created the NFCTagInfo App, available on the market. This
app is, by far, the best Tag reader, because of all the little information
it can give us, for example the HEX/ASCII values of the sectors.
Thanks!
Anyway, I just wanted to point out that it is possible
Only by putting the device in emulation mode would it be possible to
(contactlessly) read and write to the emulated mifare card, which will be
persisted to the SE. While sending NDEF data over P2P is perfectly
possible, it would not be persisted to the SE and would instead
(ultimately) be handled
With hex data on all 16 sectors why would shailen need to root the phone?
couldn't that information be sent peer to peer and then stored outside of
the SE?

Gorka,
if NFC taginfo app can provide all 16 sectors of the MIFARE
couldn't shailen have sent this to another phone via peer to peer and
avoided card emulation?
Shailen, can you share some insight into how you did this using NFC

I right? I ask you because this solution is fine for research
purposes, but it cannot be applied if you want to publish your app or
sell it.
Hallo Nick,
Understood. There was no choice but to create a new protocol, since the
rules of the NFC Forum are that you cannot implement a protocol until it
is ratified. And SNEP is not yet ratified. Rather than wait for ever, we
want to put it in the hands of users and application developers
Hallo Nick,
Just want to clarify this - NPP is an open protocol. We've published the
spec here:
http://source.android.com/compatibility/ndef-push-protocol.pdf
Sorry, I wasn't aware that the spec has already been published.
I really like the simplicity of the protocol. Especially in

I'm not sure what function you mean. In the Tags app i see a tab
called My tag where you can share your tag with other Android phones
(or any device that supports Android's non-standard way of exchanging
NDEF messages over LLCP). If that's what you mean, that's not card/tag
Hallo JMC,
I think there is a big misunderstanding out there of what card emulation
is (and what it is not!).
First of all, NFC has three different communication modes:
* Reader/writer mode,
* Peer-to-peer mode, and
* Card-emulation mode
*Reader/writer mode* is used to access NFC tag (i.e. tags

Hi Michael,
The Tag application on Gingerbread have a fouction called smart poster, is
it the card simulation? or just a tag emulation.

Hey Michael,
Why - may I ask - do you think this possibility will not be made
available to android phones? It seems to me it's a rather important
part of NFC. The part where it makes phones compatible to existing
infrastructures based on RFID (without changing those
infrastructures), namely those

the current SDK does not allow you to use card emulation.
