    Dear Support,

    The problem is solved. I can fully control the access keys of Application. I can read/write the data in files.
    The setting of bit " CHANGE KEY ACCESS RIGHT". It is very important.
    When "Change key access right" = 0xF ==> the application keys (APKs) can not be changed.

    Best regards
    Tony

    Dear Suuport.

    I get the same problem I use the PEGODA and RFIDDISCOVER V4.2.
    Please help what i need to do to use the keystore to get access in application
    this is the capture and test what I did.

    Application 00001 has 2 file
    Standard data file 01 and 02 with different key access.

    *READ AND WRITE TO FILE 01
    READ ACCESS = 0E
    WRITE ACCESS  = 0E
    READ/WRITE ACCESS = 0E
    CHANGE ACCESS = 0E

    With this key access ( no key access request :)) I can read and write to file



    *READ AND WRITE TO FILE 02
    READ ACCESS = 0E
    WRITE ACCESS  = 02
    READ/WRITE ACCESS = 01
    CHANGE ACCESS = 0E
     
    We can ONLY read, When we try to writeto file 02 We get ERROR. Please help!!!!

    Please help

    Best regards
