QR code on a mobile phone for professional accreditation.

The College of Technical Architecture of Barcelona has developed a QR code that will allow for the immediate accreditation of professional qualifications for technicians and companies in the sector.

The initiative, developed through the Business Single Window, addresses the growing need for agile tools to verify professional capacity to clients, collaborators, and subcontracted companies. This new functionality offers an additional guarantee, particularly for technical architects involved in multidisciplinary teams.
By simply scanning with a mobile phone, it will be possible to instantly check if a company or professional holds the corresponding accreditation and if it is currently valid. Each professional or company registered with RASIC has its own QR code acting as official digital accreditation.
This code can be obtained from the Company's Private Area or, for chartered professionals, through their professional college. Gestorias or authorized consultancies can also handle this process.
The new QR code helps strengthen credibility and trust within the sector. Displaying this accreditation on quotes, invoices, emails, or websites allows for simple and transparent verification of qualified professional status and aids in combating professional intrusion.
The use of the system is voluntary and aligns with the Generalitat's strategy for administrative simplification, aiming to reuse existing data to reduce procedures and improve the experience for professionals and companies.
