Open Banking is a model for sharing financial data that allows a customer to grant third-party payment service providers access to their account information or the ability to initiate payments through dedicated interfaces (APIs), solely based on the user's consent.
The following parties are involved in the interaction:
Payment Service User (PSU) – the account holder
Account Servicing Payment Service Provider (ASPSP) – Piraeus Bank ICB JSC
Third-Party Payment Service Provider (TPP) – an external service provider
Technology Operator (UPC) – responsible for technical API connectivity and interaction
Open Banking provides customers with greater control and convenience when using financial services.
