### Inspect the terminal

Because payment terminals process sensitive card data, you must verify that the terminal you received is the correct one. 

1. Verify that the shipping box containing the terminal hasn't been opened and that the box tape is intact.
2. Open the terminal 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.
3. 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.

||| Note: If any of the above checks fail, contact our **eatOS Support** immediately.
