## Discussion

For more information about using the device verification value, see [`deviceVerification`](/documentation/StoreKit/Transaction/deviceVerification).

This value is identical to the [`deviceVerification`](/documentation/StoreKit/AppTransaction/deviceVerification) value in [`AppTransaction`](/documentation/StoreKit/AppTransaction).
