In Austria Computop Paygate supports online money transfer with the Austrian Electronic Payment Standard (EPS). EPS is an established system for e-commerce payments in Austria offering a payment guarantee to the merchant. The customer can use the familiar and trusted online banking of its own credit institution, just the same as with online banking.
With online banking, the data disclosed in the online transfer is encrypted with SSL (Secure Sockets Layer) to prevent manipulation.

With the PPRO connection there are a few added parameters which are explained separately in the table. Subsequent credits and batch transfer credits can only be made with the PPRO connection.

To avoid double payments or actions (e.g. by ETM), enter an alphanumeric value which identifies your transaction and may be assigned only once. If the transaction or action is submitted again with the same ReqID, Computop Paygate will not carry out the payment or new action, but will just return the status of the original transaction or action.
Please note that the Computop Paygate must have a finalized transaction status for the first initial action (authentication/authorisation). This does not apply to 3-D Secure authentications that are terminated by a timeout. The 3-D Secure Timeout status does not count as a completed status in which the ReqID functionality on Paygate does not take effect. Submissions with identical ReqID for an open status will be processed regularly.
Notice: Please note that a ReqID is only valid for 12 month, then it gets deleted at the Paygate.
