Bank Account Verification
Product overview
Bank Account Verification verifies that the client holds a bank account with another financial institution and is the same person previously verified in a Fourthline Identity Verification.
The client transfers 10 cents to Fourthline via their own bank. We receive the funds, reconcile the payment, and then refund the client’s account within 3 business days. We automatically match the international bank account number (IBAN) and account holder name provided by the client to the bank account used for the payment.
Use Bank Account Verification in your Identity Verification solution, in combination with Qualified Electronic Signature, to offer a BaFin-compliant onboarding flow in Germany.
How it works
The flow is as follows:
Reference payment
The client starts the Bank Account Verification workflow.
Introduction screen
They are redirected to the PSP payment interface, where they select their bank. The PSP displays the payment details and the client agrees to pay.
Then, the PSP redirects the client to their banking environment, where they authorize the payment.
Tink payment interface
Tink errors
Payment confirmation
The client returns to the Bank Account Verification workflow and Fourthline displays if the payment was successful.
