    Re: WP7 and NFC?

    QT is native C++, native is not supported in WP7 (and this is good). The time for native languages is gone.
    Only managed .NET (c# and VB) is supported. So here is no way for QT in WP7.

    Re: Changing Part of the Sector Trailer

    Hi,

    hello nisar,



    ok this works, I assume you write with NDEF.


    this works too.

    Hi,



    a NDEFConnection has no knowledge about keys and don't use and
    need them. The underlaying implementation for MifareStd. use
    a standard NDEF key for access.
