European Digital Identity Wallet: selective disclosure

The European Digital Identity Wallet is a secure app that lets you prove who you are and share only specific verified attributes when crossing EU borders. For example, you can show you are over 18 without revealing your exact birth date or full name. This is different from a traditional digital ID card, which typically discloses all your identity data at once. The wallet is built on the eIDAS 2.0 regulation (2024/1183) and aims to give you control over what personal details you share, reducing unnecessary data exposure.

To avoid common exam confusion, remember that the wallet supports selective disclosure, not full disclosure. If a question describes a scenario where a citizen must reveal their entire identity to access a service, that is not the wallet's purpose. Another trick: think of it as a digital version of showing only the bouncer your birth year, not your whole passport. Also, note that the wallet works across borders, so it is not limited to one country. If an option says it only works domestically, eliminate it.

A quick way to test your understanding: ask yourself whether the wallet lets you hide your exact address when proving residency. The answer is yes, because you can share just the attribute needed. This selective sharing is the core concept to remember, not the technical details of how the wallet stores data. Focus on the principle of minimal disclosure.
