    Access MiFare Classic card: Issue while migrating code from Nokia 6131 to Nokia 600

    Hi There,

    We are working on Contactless card reader application for Nokia 6131.We are working with the 4 byte MifareClassic cards.But now have a requirement to support 7 byte UID on the same cards.

    Till now we were using MFStandardConnection Interface to get the 4 Byte UID of MifareClassic card.

    Now we need to get 7 Byte UID of MifareClassic 7 Byte UID cards.

    GetUID method on MFStandardConnection Interface returns only 4 byte UID so unable to use it now.

    I read somewhere that symbian SDK 3 includes the required JSR-257 extension. does anyone have any idea about the interface and method which could return serial number of card in this SDK for 7-byte?

    Appreciate your input.

    Regards,
    Pranaw

    Hi everyone

    MFStandardConnection throw an exception while reading Mifare card with 7 byte UID long. Connection opening URL is

    Connection.open(targetURL) return nfc:rf;type=mf1k;uid=0459873afc2480. UID parameter is 7 byte long therefore it throwing exception like
    "javax.microedition.io.ConnectionNotFoundException: Unsupported connection mode"

    If UID length 4 byte mifare card device build connection properly.
    If anybody have an idea to make MFStandardConnection for 7 byte UID long mifare card.
