  • Patent number: 10068217
    Abstract: Methods and systems for determining the status of a packaged device are disclosed. The device can include a secure microcontroller, a battery, a memory storing a status code, and an NFC antenna located in the device and communicatively coupled to the secure microcontroller. A set of instructions are stored on the secure microcontroller to write the status code to the memory. The status code is accessible from outside the sealed package via the antenna. The device could also be a POS device with instructions to process payment information received on the antenna. The apparatus could also include a power routing switch. Power could then be provided from the antenna to the battery via the switch output when the switch is in a conductive state.
