Bank Account Verification
Product overview
Bank Account Verification ensures that the client holds a bank account with another financial institution and is the same person previously verified in a Fourthline Identity Verification.
To facilitate this verification, the client transfers 10 cents to Fourthline via their own bank. 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.
Fourthline provides a bulk payout of all received client funds over a defined period, along with the necessary information to reconcile payments in your system. You can either return the funds to the client's original account or credit them to a newly opened account.
Use Bank Account Verification as part of your Identity Verification solution, together with Qualified Electronic Signature, to support a BaFin-compliant onboarding flow in Germany.
How it works
The flow is as follows:

The client starts the Bank Account Verification workflow.

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.
