    The HID 6121 is the reader you mention on NXP Mifare webpage as one of the requirements to work with SAM. I don't understand how it can't work, we specially bought it for this reason.
    I wait for good news and a solution for this problem.
    Thanks.

    Yes I see the same that the picture that you attached, and the light of the Omnikey Reader is on ( red color ) .
    The device I am using is a HTC One X, with Android version 4.2.2.
    Thanks for your answer, I will be waiting for a solution.
    Regards.
