Clover detects tampering in different ways depending on the Clover device you use.
About PIN entry devices
Payment Card Industry (PCI) compliance dictates that PIN-entry devices auto-detect if tampering of a device occurs, and if detected, lock the ability to take PIN-entry transactions. Clover devices come with sensors that are used to detect misuse or harm to your device. In rare cases, tampering may be detected if a device is dropped or shaken.
If our sensors detect tampering, you'll receive an email from Clover that a tamper has been detected. If you have questions or suspect that your device has been tampered with, contact Clover support.
Recognize a tampered device
If your Station, Mini, or Flex device detects a tamper, three potential screens might appear.
In the Setup Wizard, you might be automatically directed to the Get Help screen with the error Device tampered, return to manufacturer.
In the Setup Wizard, you might see a Tamper Detected screen.
If the device detects a tamper after activation, the following error is displayed in the Sale, Refund, Phone Sale, Authorizations, and other apps.
The only way to remove the tampered message is to request a new device from Clover support or enter limp mode. Both of these actions require owner authorization to complete.
Replace a tampered device
It is essential to replace a tampered device as soon as possible to restore full payment functionality.
All Clover devices- If tampering is detected, you can no longer accept payments and must contact our Clover Sport Help team to request a replacement.
Note: You must be an owner or admin to request a replacement device.
Place your device into Limp Mode
