Abstract: A communication system of the present disclosure includes a communication device that is communicatively coupled to a peripheral device. The peripheral device selects a selectable impedance from among multiple selectable impedances to communicate peripheral device information to the communication device. The communication device operates in an acquisition mode of operation to determine the selectable impedance to recover the peripheral device information. Optionally, the communication device can transition to a response mode of operation to respond to the peripheral device information.

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.
