| **Hardware**         | Adyen payment terminals or card readers.                                                                        |

## Delivery inspection

Because payment terminals process sensitive card data, you must verify that the terminal you received is the correct one, supplied by Adyen, and has not been tampered with.

1. Verify that the shipping box containing the terminal has not been opened and that the tamper-evident security packing tape is intact.

2. If you have access to the Adyen [Customer Area](https://ca-live.adyen.com/), log in and under **In-person payments** > **Orders and returns** find the order for your terminal. Then:

   * Verify that the **serial number** (S/N) on the box is the same as in the Customer Area.
   * Using the **track & trace** link, track the order with the carrier to verify that they confirm having delivered the payment terminal.

3. Open the box, take the terminal out of the box, and verify that the **serial number** (S/N) on the terminal is the same as the serial number on the box.

4. Inspect the terminal for tampering. Check for missing screws, additional wires or labels, holes in the device, and anything inserted in or attached to any part of the terminal.

If any of the above checks fails, contact our [Support Team](https://ca-test.adyen.com/ca/ca/contactUs/support.shtml?form=other) immediately.

## Regular inspection

Carry out the following checks regularly. We recommend you do these checks every week.

### Visual inspection

When the display of the payment terminal shows the word '**TAMPER**' or '**TAMPERED**' (or a localized version of those words), stop using the device and contact our [Support Team](https://ca-test.adyen.com/ca/ca/contactUs/support.shtml?form=other) immediately.

* Verify the payment terminal is the same as shown in our documentation, in the user manual specific for the payment terminal model.
* After the payment terminal has started up, verify the Adyen logo or your company logo appears on the terminal display.
* Verify no cameras or skimming equipment are attached to the payment terminal. Check for anything inserted in or attached to the card reader, ports, display, or keypad.

### Device integrity inspection

* Verify the payment terminal isn't physically damaged. Check for missing screws, holes in the device, and added wires or labels.
* Check your camera footage for suspicious activities around the payment terminal.
* Verify that store staff and camera footage cannot see the customers' PINs when they enter this on a payment terminal.

## Awareness of suspicious activity

* Verify the identity of any third-party persons claiming to be repair or maintenance personnel, before granting them access to modify or troubleshoot payment terminals.
* Always be aware of suspicious behaviour around payment terminals. For example, attempts by unknown persons to disconnect or open devices.
* Always report suspicious behaviour to Adyen via your manager or security officer. When in doubt, contact our [Support Team](https://ca-test.adyen.com/ca/ca/contactUs/support.shtml?form=other) directly.
