Terminal Tamper on PAX Devices

January 31, 2024

Description

What can cause a terminal tamper errors and what to do if your device shows a "tampered" or "tampering error"

What's in this article?

Bank of America payment terminals, including the Mobile Card Reader D135, have built-in tamper protection sensors designed to PCI 5.0 standard specifications. The pressure sensors inside the chassis of the device will trigger when pressure is released by being unscrewed or opened. The pressure is created by the two halves of the terminal chassis being screwed together.  

The tamper sensor may also trigger due to the following: 

  • Unscrewing and removing the terminal from the chassis
  • Loosening the chassis screws
  • Excessive shaking or jostling
  • Dropping the terminal
  • Extreme temperatures, both hot and cold

What indicates there is a tamper

When the tamper sensor has been triggered, the message "TAMPERED" or "TAMPERING" displays on the screen. The payment terminal will be unable to communicate or run any apps once a tamper has been activated. The status of the payment terminal will show as "Offline".

What to do if the terminal has a tamper

The tampered payment terminal or component must be replaced. Call support for assistance.
