Digital identity wallet

An app that holds your verified ID credentials so you can present them on demand.

Instead of carrying a plastic card or photographing a document, a person opens the app on their phone and approves sharing exactly what a service asks for, such as a name, an age check, or a license.

A user-controlled store of verifiable credentials that can reveal just the attribute a service actually needs, for example proving you're over 21 without showing your name, address, or ID number at all. Sharing only the needed attribute is called selective disclosure.

A wallet typically works like this:

1. A trusted issuer, such as a government agency, proofs the person and issues a credential.
2. The wallet stores the credential on the person's device.
3. A service sends a request that lists the attributes it needs.
4. The person reviews the request and approves it, and the wallet returns a signed response.
5. The service verifies the signature to confirm the credential is genuine and unaltered.

Wallets can hold several kinds of credentials:

• Government identity documents, such as a mobile driver's license or a national digital ID.
• Proofs of a single fact, such as being over a certain age.
• Other credentials, such as professional licenses or education records.

Governments are building wallets of their own. The European Union's revised electronic identification regulation, eIDAS 2, requires every member state to offer a European Digital Identity (EUDI) wallet to its citizens, and the UK is rolling out its GOV.UK Wallet. Incode has covered both mobile driver's licenses and the UK's move toward digital government IDs.
