Second, you are certainly wrong with MIFARE 4K beeing a Type 4 NFC tag! MIFARE 4K (and so does MIFARE 1K) use a proprietary protocol that is not specified as part of the NFC Forum's NDEF tag specifications. Still, once the embedded secure element is enabled for card emulation the MIFARE 4K area is readable and writable with the default keys. So it could probably be used with *some* NFC devices as NFC tag. Remember, however, that not all NFC devices support MIFARE 1K/4K. Also, this only allows external access to the MIFARE area. Internal access, i.e. through an app on the same phone, is still not easily doable. (It can be done with firmware modifications and it can be done through components installed as part of Google Wallet.) > That said, full card-emulation is possible on the Nexus S!! > I certainly would not call this *full* card emulation. Especially as you cannot modify the card content from within the phone. br Michael -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
