    Abstract: A device implementing a system for NFC communication with a second device includes an antenna and a processor configured to transmit a pulse signal for detection of another device within proximity of the device, and to detect, in conjunction with transmission of the pulse signal, that a first value of a measurement parameter of the antenna satisfies an initial detection factor. The processor is further configured, in response to the detection, to set a confirmation detection factor for the measurement parameter of the antenna based at least in part on the first value of the measurement parameter of the antenna, to transmit a confirmation pulse signal, and to initiate a second polling for reception of data from the other device when a second value of the measurement parameter of the antenna detected in conjunction with transmission of the confirmation pulse signal satisfies the confirmation detection factor.

    Abstract: A device implementing a system for preventing duplicate wireless transactions includes a wireless communication controller that is configured to receive a signal for conducting a wireless transaction with a wireless transaction terminal. The wireless communication controller is further configured to determine whether a transaction type of the wireless transaction is associated with a signal strength threshold. The wireless communication controller is further configured to measure a signal strength associated with the wireless transaction upon determining that the transaction type of the wireless transaction is associated with the signal strength threshold. The wireless communication controller is further configured to prevent the wireless transaction from completing when the transaction type of the wireless transaction is associated with the signal strength threshold and the measured signal strength fails to satisfy the signal strength threshold, otherwise allow the wireless transaction to complete.

    Abstract: A device implementing a system for NFC communication includes a processor configured to receive, from an other device, pulse signals for detecting proximity of the device with the other device. The processor is further configured to determine an interval at which the pulse signals are received from the other device. The processor is further configured to determine a time when the other device is expected to transmit a subsequent pulse signal based at least in part on the determined interval. The processor is further configured to transmit a signal to the other device based on the determined time when the other device is expected to transmit the subsequent pulse signal.
