Saving data on internal secure card

[SomeoneSI]

Is there any other/better option to save data on internal secure card than with ISO14443Connection?

I have problems with sending commands to secure card over ISO14443 Connection. Is there any example available to see how things should be done correctly(open connection, select?, read/write, close connection)? Examples that are in 6131 SDK are only for exchanging data. There is no example how to save data on secure card/element.

Just for storing data you could also use the "com.philips.rf.MifareStdConnection" in order to save data to the Mifare Section of the smartcard.

Acutally the "javax.microedition.contactless.sc.ISO14443Connection" is used to exchange data (APDUS) with Java Card Applictions running on the Javacard in the smartcard.

Is this working on mobile version of java? When I try to compille I get error "packagecom.philips.rf does not exist import com.philips.rf.MifareStdConnection;". I tried in applet and in midlet source(midlet source have included emulator.jar to compile things for secure card).

I just want to save data/ read data with midlet or with applet on mobile to mobile secure element.

please see this thread for details on how to open a connection to the mifare section of the secure element:

I think, the right package for MFStandardConnection in Nokia_6131_NFC_SDK_1_0 environment is "com.nokia.nfc.nxp.mfstd".

currently the mifare standard connection is not (yet) implemented on the nokia 6131 (got this information from Nokia). There is only a possibility to use the apduExchange() command to talk to the java card.
