EUDI Wallet and digital credentials, explained
Each guide takes one topic from the European digital identity rules and answers the same three questions: what it is, why it matters, and who has to do what. They are meant to be read on their own, in any order.
They are written for the people who decide what an organisation builds or buys: product owners, compliance officers and the managers who have to sign off on a wallet programme. No specifications to read first.
