  Competent authorities connecting to the Once-Only Technical System stand to benefit most from this event. Participation will be especially useful for newcomers and authorities in the population, education and business domains. This event will also be a great opportunity for technical leads to prepare for live transactions and for UX and design teams to explore these topics. Single Digital Gateway national coordinators and team members working on implementing Once-Only in their Member State are warmly invited to join as well.

Description

The “Europe goes Once-Only” event series accelerates the onboarding of national competent authorities to the Once-Only Technical System. It brings experts working on Once-Only from all over Europe directly to the Member States to discuss, learn and overcome challenges together.

“Europe goes Once-Only – Portugal edition” is organised under the motto “Facing challenges together”. In this spirit, this event brings together competent authorities connecting to Once-Only with the national and Commission teams implementing this system. At the heart of this event are six interactive, two-day workshop tracks that will allow participants to understand how to onboard to Once-Only, share the challenges they face and collaboratively work on concrete solutions to overcome them.

Four workshop tracks are tailored to competent authorities, namely newcomers and those in the population, education and business domains. Two additional tracks will support national teams in preparing for live transactions and rolling out Once-Only services and provide a chance to discuss “hot topics”.

This event will also showcase national initiatives related to Once-Only, such as Mosaico and the Portuguese Digital Wallet. Finally, it will explore key issues related to User Experience as well as accessibility and usability.

“Europe goes Once-Only – Portugal edition” is organised by the Portuguese Administrative Modernization Agency (AMA) and the European Commission. It builds on the success of previous events organised in Finland(opens in a new tab) and Lithuania(opens in a new tab), which brought together more than 300 experts from 26 Member States and EFTA countries.
