He Steffen,
I did not find anything. I believe this is OK since there is no consensus on just about anything with respect to identity. In Sweden you cannot do anything without a "personnummer" while in France, this is considered against the constitution.

In https://github.com/eu-digital-identity-wallet/eudi-doc-standards-and-technical-specifications/blob/main/docs/technical-specifications/ts12-electronic-payments-SCA-implementation-with-wallet.md#23-sca-attestation-metadata I found this little gem:
"schema": "urn:eudi:sca:payment:1",
"claims": [
{
"path": [ "payload", "transaction_id"],
"visualisation": 4,
"display": [
{
"lang": "de-DE",
"label": "Transaktionsnummer",
"description": "Eindeutige Nummer der Transaktion"
},
{
"lang": "en-GB",
"label": "Transaction ID",
"description": "Unique identifier of the transaction"
}
]
}
This is not how the industry at large deals with multiple languages and localization. For the "SCA Rulebook" they are [still] waiting for the "industry" to fill in the blanks...
As a Technologist, European (SE/FR), Consumer, and Tax-payer, I feel a bit concerned.
I also wonder where NFC is. QR is beginning to get on my nerves with tons of different apps op the phone. There simply MUST be a better way!
Regards,
Anders
