Understanding tamper

A tampered device may be compromised and unsafe to use.

This can occur if the reader was:

• Physically shaken
• Dropped
• Subject to attempted unauthorized access

If your terminal reader detects a possible security breach, it will display a tampered message.
If you see this message, immediately stop using the device and contact Stripe or your platform. The terminal reader will need replacement.

Smart reader: S700, WisePOS E

If you see on-screen messages like those shown on the BBPOS WisePOS E or Stripe Reader S700, your device has detected a tamper and entered a tampered state.

Mobile readers: Stripe Reader M2, WisePad 3

Indications

• SDK integration: A TerminalException with TerminalErrorCode READER_TAMPERED indicates your device is compromised
• Stripe Reader M2: Rapid flashing of first and last LEDs (every 0.1 seconds for 30 seconds) indicates tampering
• WisePad 3: Displays a tamper detected screen error and becomes unavailable

What to do next

Once tampered, the reader's payment keys are automatically erased for security.

• Replacement Required: The device must be replaced and cannot be reactivated.
• Warranty Claims:
  • If under warranty, contact Stripe support with your device's serial number.
  • If purchased through a Connect platform, contact your platform provider directly.
