XS2A.pay is a payment initiation service. For the transfer, the customer simply uses his online banking access data.
Optional security checks are performed to counter fraud and other suspicious activities. Then the transfer of a fixed amount and a specific purpose is sent to a pre-defined recipient account.
The customer authorizes the transaction with a TAN, which his bank uses to execute the transfer.
