Point me to Literature for NFC Tag Read

  • Hi,

    I have used a few examples for tag read and am able to read and right a tag
    But am not able to change Either Security Key A/B or Read/write a particular Sector/Block,
    I went through " NFC Classes " But totally missed something some where.
    Please point me in the right direction.


  • Look at the QNearFieldTagType1, QNearFieldTagType2, QNearFieldTagType3 or QNearFieldTagType4 classes, they have methods for reading and writing particular sectors/blocks.

    The API does not provide methods for changing security keys, you can however use QNearFieldTarget::sendCommand() to send a raw command to the tag. You will need to construct a command appropriate for your tag type.

  • Thanks,

    I looked into this and have to dig a bit further.
    Thanks again.
