Over the course of four years (2021 to 2024), the four showcase projects \u2013 IDunion, ID-Ideal, ONCE, and SDIKA \u2013 have worked on more than 100 use cases related to secure digital identities. These projects have also developed various types of wallets, which have been tested and implemented in multiple pilot environments. The Showcase Program has supported Research & Development (R&D) efforts, resulting in the creation of seven edge wallets, three organizational wallets, and one cloud wallet. Within this framework, IDunion has specifically focused on developing organizational identities, including use cases such as „Know-your-supplier.“ This paper outlines the cost savings achieved through automated supplier master data management, leveraging EUDI wallets for legal entities and the EU Company Certificate Attestation (EUCC) issued by QEAA providers in accordance with Company Law.

Large corporations need to maintain and assure high quality of several hundred up to millions of master data records. The maintenance costs per single data set was estimated to 11 \u20ac\/year. The master data set considered for the cost estimation was limited to company name and address data and therefore is a subset of the data that will be available with the PID for legal person and the EUCC.

Solution based on EUDIW<\/strong>: EU Digital Identity Wallets (EDIW), PID for legal entities and public registry extracts (e.g. EUCC) as QEAAs enable almost completely automated management of business partner data. Suppliers present their attestations from their legal entity wallet to customers or legal entity wallets of other business partners. Presentation, verification and the transfer to internal systems is performed automatically. This reduces the number of proprietary data records maintained in parallel and minimizes manual, error-prone data entry.
Cost savings<\/strong>: The solution enables annual savings of estimated \u20ac85 billion for German companies. Only German companies with more than 2 million sales\/year where included in this estimation. It was assumed that only their European business partners provide their data as verifiable attestations. This underscores the transformative impact of the EUDIW solution on master data management and its strategic importance for the private sector on the path to digital efficiency.<\/p>\n\n\n\n\n
