| `device_state`              | An enum of the type `ped_state` that indicates the device state. The ped\_state must reach the status `ped_state_operational` before the transaction is considered complete.Before completing the transaction, the system can return callbacks that show a change in PED state. The `terminal_id` is recorded in the Adyen payments platform, both in the transaction view and in the device state.The device state can encounter any of the following statuses, though not always in this order. Cycling through each state is not mandatory. The POS must take action on the `ped_state_operational` status before performing a transaction. The other states are provided for information only and do not require action from the POS. |
| `terminal_id`               | The `terminal_id` of the PED.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             |

The `terminal_id`, `terminal_serial_number`, `terminal_type`, `terminal_brand`, `terminal_api_version`, `terminal_os_version`, and `terminal_hardware_version` data elements are used to define the exact state of the PED. Use these elements to investigate issues.

These data elements are recorded in the [Customer Area](https://ca-test.adyen.com/). For each transaction, this PED ID is listed to trace back the origin of a transaction to the PED on which it had been executed. The Customer Area shows all configuration details for each PED, and offers functions to change these details.
