  • Systems and methods for determining whether a companion communication device is beyond a proximity of a primary communication device
    Patent number: 9225393
    Abstract: Systems and methods for determining whether a companion communication device is beyond a proximity of a primary communication device are provided. In some aspects, a system includes an analysis module configured to determine whether a wireless transaction between the primary communication device and the companion communication device is at a conclusion. The system also includes a communications module configured to emit a sensing signal based on the determination of whether the transaction is at the conclusion. The sensing signal is insufficient to elicit a response from the companion communication device. The system also includes a detection module configured to detect a present parameter associated with the emitted sensing signal. The analysis module is configured to determine a parameter change between the present parameter and a reference parameter, and to determine whether the companion communication device is beyond the proximity of the primary communication device based on the parameter change.
