EUDI & eIDAS 2.0 glossary pt.1

The EUDI wallet is set to make our lives easier. We will be able to log in to services without usernames and passwords, onboard to services without plastic documents, and authorise payments and money transfers without one-time passwords sent via SMS.

Let’s see what makes the whole ecosystem work. 

Wallet 

An app on your phone. Each EU country will have one, and they should all work in the same way. The wallet is your document folder or a database of different credentials. 

PID

Your main government-issued identity credential. In the beginning, you will be able to add PID only to the government wallet. Think about PID as an alternative to your plastic ID document. 

Relaying Party

(Wallet) Relaying party, or RP in short, is a business that wants to read data from the wallet. A car rental company or a bank is a “relaying party” that needs to process data from a wallet.

Relaying Party Intermediary

Most businesses will work with intermediaries to get access to wallets. It’s easier and much cheaper to use one of the intermediaries than to deal directly with the complexities of hosting your own verifier service. 

Verifier

The technical infrastructure needed for Wallet communication is called “verifier”. The name comes from the fact that you need to verify incoming information, if it comes from a legitimate source and hasn’t been tampered with.
