[android-developers] Re: does NFC in gingerbread support card simulate?

Hello Michael,

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.

Anyway, I just wanted to point out that it is possible to simulate an NFC Tag with card emulation. I was able to turn on card emulation on my Samsung Nexus S phone which sports a PN65 (=PN544+SmartMX) chip. The emulated card was a MIFARE 4K, which is a Type 4 NFC Tag. Using another Nexus S and the NXP TagWriter app, I was able to write a plain text message on the card-emulated Nexus S.

Examining the HEX data, the latter was clearly an NDEF message. Furthermore, the NXP Tagreader app was able to extract the plain text message.

That said, full card-emulation is possible on the Nexus S!!

Hallo,

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

Anyways, with card *emulation* you will not be able to simulate an
*NFC tag* (i.e. a tag where you store simple NDEF messages). Card
emulation mode allows to emulate a contactless smartcard (typically
used for applications with high security requirements, like credit
cards). While such a card (emulated or real) can be used to carry NDEF
messages, I really doubt that this possibility will be made available
for the Android phones.

Michael
