Relying Parties	A Relying Party (RP) is an entity that interacts with EUDI Wallets to verify a user’s identity and attributes for authentication, authorization, or service access. The scope of the EUDI Wallet ecosystem is to create a public and private ecosystem. Both public and private Relying Parties must register and declare their intended use of the EUDI Wallet to ensure compliance with the EUDI wallet ecosystem based on the eIDAS 2.0 regulation.

Wallet Ecosystem

Element	Description
Registrar / EMP	Ecosystem operator which is providing the Ecosystem Onboarding and also working as the registrar for Relying Parties.
Wallet Unit	The wallet downloaded and installed by the Wallet User on their own compatible device.
Wallet Backend	Backend provided by the Wallet Developer. The Backend fulfills the tasks necessary to check that the Wallet User has installed a proper wallet on a trustworthy device.
Access Certificate Provider	Provider of certificates for central ecosystem components such as the registrar as well as the PID Provider.
PID Provider	A PID Provider is a trusted entity responsible for verifying the identity of the user in compliance with LoA high requirements, issuing a PID to the Wallet, and making information available in a privacy-preserving way so Relying Parties can verify the validity of the PID. The PID Provider ensures that person identification data, such as name and date of birth, is securely generated, validated, and seamlessly provided. The PID Provider is part of the infrastructure of the German EUDI Wallet ecosystem. In the future, additional PID issuance methods that meet the functional and security requirements may be evaluated as part of the German EUDI Wallet project. The EUDI Wallet ecosystem envisions a single PID Provider.
AppStores / OSs	Apple App Store or Google Play Store as sources where the EUDI Wallet can be downloaded and installed; the operating systems iOS and Android are supported.
Wallet User	Citizen using the EUDI Wallet.
