SOFORT is designed to be one of the most secure online payment systems. The net transfer is made using the bank's login process combined with a confirmation code (TAN). This provides a high protection against misuse as the code can only be used once and becomes immediately invalid.
Entering login details, such as PIN and TAN, takes place exclusively in the secure payment platform of SOFORT and not on the seller’s website. This ensures that the seller does not have access to sensitive information, such as PIN and TAN. The data is only transferred via high-security connections. SOFORT itself does not store any sensitive information, as they are only a technical service provider.
