PostFinance Pay is a new online payment method in Switzerland, replacing the previous PostFinance E-Finance and PostFinance Card payment methods. Customers can pay conveniently via the PostFinance app. ​The mobile payment solution PostFinance Pay is linked to the PostFinance bank account and the PostFinance app. It allows Swiss customers to pay for their online purchases directly from their bank account without having to enter their bank card details.

According to Worldline's documentation, PostFinance Pay is available in several European countries, including Hungary. However, it's important to note that payment transactions are made in Swiss francs (CHF) and customers must have a PostFinance account and app to pay.

PostFinance Pay is primarily popular in Switzerland, and some European merchants may also integrate this payment method, especially if they are targeting Swiss customers. However, it is important to note that payment transactions are made in Swiss francs (CHF) and customers must have a PostFinance account and app to pay.

PostFinance Pay is limited to use outside the European Union as it is primarily designed for Swiss customers. While it may be technically possible for international merchants to integrate the system, in practice this is less common and customers still need a Swiss PostFinance account and app to complete transactions.
