1. A wireless integrated circuit memory device for transmitting encrypted data from the wireless integrated circuit memory device to a wireless device, over a local point to point wireless communication, the wireless integrated circuit memory device comprising:

  • a memory controller;

    memory that includes a protected memory area for storing protected data, the protected data stored in the protected memory area is not accessible by a user of the wireless integrated circuit memory device, from the protected memory area, but is accessible by the memory controller; and

    wireless communication circuitry, wherein the wireless integrated circuit memory device is operable to;

    (1) access, by the memory controller of the wireless integrated circuit memory device, the protected data that is stored in the protected memory area, the accessing of the protected data from the protected memory area is based on the memory controller implementing a cryptographic algorithm;

    (2) encrypt data, at the wireless integrated circuit memory device, into encrypted data, the data, at the wireless integrated circuit memory device, is related to the protected data accessed by the memory controller from the protected memory area of the wireless integrated circuit memory device in (1);

    (3) wirelessly discover, over the local point to point wireless communication and via the wireless communication circuitry, the wireless device;

    (4) establish, via the wireless communication circuitry of the wireless integrated circuit memory device, the local point-to-point wireless communication link between the wireless integrated circuit memory device and the wireless device discovered in (3), the local point-to-point wireless communication link being a radio communication link;

    (5) wirelessly transmit, via the wireless communication circuitry of the wireless integrated circuit memory device, at least part of the encrypted data encrypted in (2), over the local point to point wireless communication link established in (4), directly from the wireless integrated circuit memory device to the wireless device wirelessly discovered in (3); and

    (6) receive, at the wireless integrated circuit memory device and over the local point-to-point wireless communication link established in (4), information from the wireless device discovered in (3), the information is related to one or more of payment information, status information, or output process information, individually or in any combination; and

    wherein the wireless integrated circuit memory device provides protection of the protected data by storing the protected data in the protected memory area and requiring use of the wireless integrated circuit memory device for wirelessly transmitting the encrypted data directly from the wireless integrated circuit memory device to the wireless device.
