Overview

IRIS R18 is a lightweight, standards-based solution that uses vanilla OFS to communicate with T24. It can be used by all T24 customers.

PSD2 Overview

PSD2 is a European directive that requires banks to open their accounts for third-party providers. It is a European Commission proposal to create secure and innovative European payments (PSD2). The main aim is to protect consumer online transactions and promote innovative online services through open banking.

The European Union has published a new directive on payment services in the internal market and the APIs covered are:

• Payment Service Directive (PSD2), which contains regulations of new services to be operated by Third Party Payment Service Providers (TPP) on behalf of a Payment Service User (PSU). These new services are
• Payment Initiation Service (PIS) - Operated by a Payment Initiation Service Provider (PISP) TPP.
• Account Information Service (AIS) - Operated by an Account Information Service Provider (AISP) TPP
• Confirmation of the Availability of Funds - Used by a Payment Instrument Issuing Service Provider (CBPII) TPP.

PSD2 APIs Deployment Structure

The below diagram explains the deployment of PSD2 APIs in a bank. This diagram may vary depending on the banks’ network deployment architecture.

PSD2 APIs are encapsulated and available through Interaction Framework (IRIS) war files. It needs to be deployed in the bank’s internal network zone. The IRIS infrastructure interface uses the required connectors to interface with T24. Based on the TAFJ deployment, these IRIS connectors need to be appropriately configured.

PSD2 Distribution Package

The PSD2 Distribution Pack consists of the following:

• irf-api-m2repo.zip - Binaries required for PSD2 specific implementation.
• irf-m2repo.zip - Binaries required for generic IRIS R18 implementation. For example, building a custom container with various deployment profiles.
• irf-psd2-PZ.war - War that comprises APIs for Account Information Services (AIS) and Confirmation of Funds Services (CBPII).
• irf-psd2-PX.war - War that comprises APIs for Payment Services (PIS).
