Except where preview is not required by national law, users must be offered the possibility to preview the evidence before they decide to proceed with the evidence exchange.
If the user decides to proceed, the evidence provider will respond to the second evidence request messages from the requester with the evidence(s). The user is redirected back to the requester side upon confirming or cancelling the evidence exchange.


Understand how the Once-Only Technical System connects public authorities so that they can exchange evidence at the request of a citizen or business, by navigating our prototype.
