Processing payments in Greece

In Greece, payments processed via a payment terminal must be confirmed (signed) in advance.

The following procedure must be followed:

1. The provider must issue a unique signature based on the payment to be made.
2. This signature must then be transmitted to the acquirer's payment application,
   1. where the signature is authenticated and
   2. the actual payment process is initiated.
3. After the payment process, the response (confirmation of the payment process) must first be transmitted to the requesting system (ERP, cash register), which transmits the confirmation in the JSON payload to the provider.

In this context, ‘providers’ are understood to be myDATA providers that are connected to RetailForce.
