Unzer Bank Transfer

Learn more about Unzer Bank Transfer and payment workflow.

Unzer Bank Transfer lets you accept a direct transfer from the customer’s bank account which follows the same flow as for example, EPS or Sofort. When the customer uses Unzer Bank Transfer for payment, they are redirected to the Unzer Bank Transfer web page. The customer will log in with their bank details for authentication. After a successful login, Unzer Bank Transfer initiates a payment transaction with the customer’s bank account.

The customer needs to provide their bank account login credentials and authorize the transfer through their one-time password (OTP) device, usually through a transaction authentication number (TAN) received in a text message.

  • Increased customer confidence: The customer does not need to go to any unknown portal to make the payment, and hence the possibility for a successful transaction is higher.
