1. A payment object reader that preemptively prepares one or more subsystems, the payment object reader comprising:
- a wireless transceiver;
a reader interface that reads transaction information from a payment object;
a non-transitory computer-readable storage medium storing instructions;
a first processor; and
a second processor, wherein execution of the instructions by the second processor causes the second processor to;
measure performance of the wireless transceiver over a time period using a performance metric,detect that the performance of the wireless transceiver has dipped below a performance threshold, andboot the first processor up from a powered down state in response to detecting that the performance of the wireless transceiver has dipped below the performance threshold.

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.
