Introduction

EPS is an electronic bank transfer solution that is exclusively used in Austria. It is a secure online payment system for web shops, as the transfers are processed only via your own bank's secure online banking. There is no need for an additional customer account with a payment service or another app; the login details for your own bank account are sufficient. When you are redirected to your online banking, the ordering process in the web shop and the payment process are strictly separated.

Over 11,000 online shops already offer quick, easy, and secure payment via EPS transfer. Many official electronic transactions in Austria are also carried out this way, as EPS is the widely used online payment method for e-government. The EPS transfer was developed in cooperation with Austrian banks.
