Hi,

I´ve been working on NFC with my Samsung 5230 mobile, and now I am
considering to move to Android. Before I do that I have some
questions. I´ve been reading the group and the developers web page,
but still have some doubts.

- Is it possible to read MIFARE DESFire tags using the standard API.
In order to do that I have always used the JSR 257 spec. but I don´t
know if it is possible to do something similar with the current
Android version.

- Suppose that I have a tag that is a sticker always affixed to the
mobile phone. Is it possible to read it always my application is
started?? In the mobile I used to work with it was a limitation since
once the sticker was detected the first time it could not detect it
anymore until I removed the sticker from the mobile NFC range and got
it close again. Would be possible using Android API to detect it
anytime I start the app without having to remove it??

- I am working on JavaCard too and I have developed an applet in order
to complete the authentication steps in a secure way. Is it possible
to access JavaCard applets in my SD card using Android API. Until that
moment I have used the JSR 177 (APDU Connection, ...) in order to do
that. The problem with others mobile is that to access the SD you have
to sign your midlet with a Verysign certificate, but I don´t want to
do this.

Thanks a lot.
Best regards.
