Description

With the account from PostFinance your customers pay for their purchases direct via computer or mobile telephone. The payment is made with the PostFinance Card or PostFinance E-Finance. The payment solution "eCom" from Datatrans offers you the opportunity of activating both methods of payment.

Money transactions are settled round the clock via the internet using e-finance. With about 1 million customers, PostFinance is the leading platform for online finance.

Proper Redirects

Lightbox Mode: When using PostFinance (PFC, PEF) or SwissBilling (SWB) make sure to also submit the uppStartTarget=_top parameter. This ensures that a proper redirect is made to the respective systems.
