Getting Nexus S Android NFC into Card emulation mode

Question

Has anyone been able to get the nexus s into card emulation mode?

The latest android release does not seem to support this yet.

This article says it's possible http://www.nearfieldcommunicationsworld.com/2011/02/13/35913/uncovered-the-hidden-nfc-potential-of-the-google-nexus-s-and-the-nokia-c7/

Answer 1

Long story short:

Yes, it's possible, but only if you hack. The article you've posted shows how it's done.

Such a hack will only work with the Nexus-S, and only on modified phones with android 2.3.3 Everything relies on undocumented framework classes that may change anytime.

With the official android SDK it is not possible.

Answer 2

Here you can download a patch for Gingerbread who enable card emulation : http://groups.google.com/group/android-developers/browse_thread/thread/d5fc35a9f16aa467/dec4843abd73d9e9%3Flnk%3Dgst%26q%3Dsecure%2Belement%2Bdiff%2527s%23dec4843abd73d9e9

The emulated card will be Mifare Classic 4K.
