OIX is working with some banks and there is a system in testing to verify digital identity.
Extract from the document below;
HSBC, Barclays, Government Digital Service, OT-Morpho, Orange and OIX UK have formed a Consortium to deliver a digital identity project that will develop and test a prototype to enable an EU citizen to open a bank account in another European country using their national digital identity. It will build the service design and operational framework and will deliver a business case for the development of the fully operational service that will enable a more trustworthy and efficient account opening process for EU citizens across Member States. The project is specifically focused on the use case of a French citizen wishing to open a bank account in the UK prior to moving into the country.
