August 13, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- A patent by the inventor Fisher, Michelle (Oakland, CA), filed on December 6, 2011, was published online on July 29, 2014, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 8792939 is assigned to Fisher; Michelle (Oakland, CA).

The following quote was obtained by the news editors from the background information supplied by the inventors: "A secure element can be physically coupled to a mobile communication device to allow for transactions with remote terminals such as point-of-sale and point-of-entry terminals. Implementing wireless communications between the mobile communication device and the secure element, however, presents challenges. For example, it is desirable to transmit data between the mobile communication device and the secure element in a manner that allows for easy receipt of the data especially in cases where a wireless carrier network or WIFI connection is not available. Also, a method of communication between the mobile communication device and the secure element should allow for convenient activation of the secure element and remote deactivation of the secure element."

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventor's summary information for this patent: "Disclosed embodiments allow a mobile communication device to communicate non-wirelessly with a secure element that is physically coupled to the mobile communication device. Communications from the mobile communication device to the secure element use a different protocol than communications from the secure element to the mobile communication device.

"In some embodiments, a system includes a mobile communication device and a secure element physically coupled to the mobile communication device. The mobile communication device includes a first wireless transceiver, first processor, first memory, first microphone, first speaker, first audio to digital converter(ADC), first battery, and audio port. The secure element includes a second wireless transceiver, second processor, second memory, a second audio to digital converter (ADC), a second audio to digital to audio converter (DAC), and an audio cable with 3.55 mm plug that can be inserted into audio port of mobile communication device. The mobile communication device is configured to transmit data via the audio cable connected to the secure element. The secure element is configured to transmit data via the audio cable to the mobile communication device

"In some embodiments, a method of communicating between a mobile communication device and a secure element physically coupled to the mobile communication device is performed. The mobile communication device includes a first microphone, first wireless transceiver, first processor, and first memory, and the secure element includes a second wireless transceiver, second processor, and second memory. The method includes non-wireless transmission of data between the mobile communication device and the secure element via a cable that connects from the secure element into the audio port of the mobile communication device."
