1. An apparatus comprising:

  • a sealed package;

    a point of sale device located inside the sealed package;

    a secure microcontroller located in the point of sale device;

    a battery;

    (i) located in the point of sale device; and

    (ii) ohmically coupled to the secure microcontroller;

    an electrically programmable memory in the point of sale device storing a status code for the point of sale device;

    an NFC antenna located in the point of sale device and communicatively coupled to the secure microcontroller;

    a status monitoring circuit located in the secure microcontroller;

    a set of instructions stored on the secure microcontroller for execution by the status monitoring circuit to periodically refresh the status code in the electrically programmable memory;

    an NFC front end chip;

    a set of instructions stored on the secure microcontroller to;

    process payment information received from the NFC antenna; and

    write the status code to the electrically programmable memory;

    wherein the status code is accessible from outside the sealed package via the NFC antenna;

    wherein the electrically programmable memory is volatile;

    wherein the secure microcontroller is communicatively coupled to the NFC antenna via the NFC front end chip; and

    wherein the status monitoring circuit and the NFC front end chip are both configured to receive power via the NFC antenna when the status code is accessed from outside the sealed package.
