Abstract
A payment processing device can implement a monitoring system to detect for tamper attempts at a physical interface such as a chip card interface. The monitoring system can establish local tamper criteria including a baseline when no chip card is present in the chip card interface, or in some embodiments, when it is known that an authentic chip card is present in the slot. During subsequent evaluations of the chip card interface by the monitoring system, a response received by the monitoring system that deviates from the local test criteria can indicate that a tamper attempt at the chip card interface may have occurred. The payment processing device may also communicate test results to a server for further testing, or for an update of the local test criteria.
