It would be nice to get a hint on when card emulation will be added as
an official feature of the SDK. It's already mentioned in the source
code (NfcAdapter.java) but hidden with @hide.
/**
* Card Emulation mode Enables the manager to act as an NFC tag.
Provided
* that a Secure Element (an UICC for instance) is connected to
the NFC
* controller through its SWP interface, it can be exposed to the
outside
* NFC world and be addressed by external readers the same way
they would
* with a tag.
* <p>
* Which Secure Element is exposed is implementation-dependent.
*
* @hide
*/
private static final int DISCOVERY_MODE_CARD_EMULATION = 2;
It seems to be possible to enable this somehow (http://www.youtube.com/
watch?v=28TwCpx4Dng) but I don't know if it requires Java reflection,
NDK programming or a custom Android build.
