<h2>Introduction to the Once-Only Technical System (OOTS)</h2>
<p class="mb-0">The Once-Only Technical System is a technical framework for data sharing. As of the end of 2023, citizens and businesses will be able to request official documents (known as “evidence”) to complete administrative procedures allowing people to study, work, live and retire in other EU countries

 in 7 simple steps. The decentralised architecture connects public authorities, so they can exchange 

evidence at the citizen's or business' request.
