1. An apparatus, comprising:

  • a network interface;

    a memory to store instructions; and

    processing circuitry, coupled with the memory and the network interface, operable to execute the instructions, that when executed, cause the processing circuitry to;

    receive, via the network interface, a first message to determine whether an applet is enabled or disabled for a transaction card, the first message comprising a counter value and an applet identifier to identify the applet, wherein the counter value is associated with the applet, and the counter value is one of a plurality of counter values and each of the plurality of counter values is associated with a different one of a plurality of applets;

    determine a second counter value stored in storage, the second counter value associated with the transaction card;

    compare the counter value and the second counter value to determine whether the applet is enabled or disabled for the transaction card;

    based on the comparison between the counter value and the second counter value, determine the applet is enabled for the transaction card;

    communicate a second message, comprising an indication the applet is enabled for the transaction card;

    receive a second indication to disable the applet on the transaction card, the second indication to disable the applet comprising the applet identifier to identify the applet and the counter value stored on the transaction card and associated with the applet; and

    set the second counter value associated with the applet to a value in a data store storing one or more counter values for the transaction card, the value to indicate the applet is disabled.
