  • Point of sale (POS) device responsive to detected interference with antenna
    Patent number: 10182328
    Abstract: A payment object reader or POS device tracks performance of a wireless transceiver. In response to detection of a dip in performance of the wireless transceiver, the payment object reader or POS device retunes the wireless transceiver, enables a first subsystem of the payment object reader or POS device from a disabled state, transmits a notification indicating a defect, or identifies a tamper attempt. Sensor measurements and other actions within the payment object reader or POS device can be correlated with wireless transceiver underperformance and used to predict actions to take.
