Take a team in Lyon that wants to offer a mobile account to students and young professionals. Before its presentation meeting with the ACPR authorisation department, we set up an environment in its brand and draw the flow of funds with it: app, ledger, safeguarding account, card issuer.
Once the file is in, the ACPR comes back with questions and the Banque de France looks at payment security. The team answers from what already runs: two-factor login, limits, fund reconciliation on test data. On authorisation, the same platform opens to the first customers.
For the regulatory side, read our ACPR licence guide and the overview of e-money institutions in the EU.
