    How can I limit the number of negative verification attempts of a Ultralight EV 1 tag using the Taplinx SDK?

    Regards.

    Hi Francisco,

    There is no “failure counter” in TapLinx as I know. But I will ask the development team if negative attempts can be checked or limited.

    Perfect. Do you know when I will have an answer to the question?

    Hi Francisco,

    I got the answer: there is no “failure counter” in TapLinx.

    For effective attack protection, this feature must be implemented in the tag, and not in movable software library. The MIFARE Ultralight C is not a high security product, so the Ultralight does not support such feature.

    If it is important for you, please have a look to our JCOP Smartcard products. Here you will find such features.

    Sorry but that is an very inadequate answer. As clearly stated in the title I am asking for Ultralight EV 1, not Ultralight C.

    According to this document (http://www.nxp.com/documents/data_sheet/MF0ULX1.pdf), as stated in page 17, section 8.6.2; Ultralight EV 1 does in fact count with such feature. I just want to know if Taplinx SDK provides access to that feature in Ultralight EV 1.

    Am I missing something?

    Hi Francisco,

    Sorry, my mistake. Yes, the Ultralight EV1 has a protection mechanism for memory access. And it is not supported by TapLinx, as the development team replies.
