Oracle Payment Interface (OPI)

Our Oracle Payment Interface (OPI) enables EMV payment processing for Micros point of sale (POS) systems.

Certified by Oracle, this solution expands payments for Micros RES 3700, Simphony, and E7 with Heartland's out of scope semi-integrated EMV payment application for seamless and secure transaction processing, while reducing merchant chargebacks and fraud.

Our OPI offers several features that together provide an out-of-scope middleware solution that makes in-person payments easy and simplifies merchant PCI compliance:

• Micros merchants can process EMV chip cards to reduce chargebacks and fraud.
• It’s compatible with Micros e7, Micros 3700, and SIMphony systems.
• You can easily add EMV payment processing with no changes to existing workflows.
• It improves the customer experience by expanding payment acceptance.
• It’s built on Oracle’s dealer-friendly retail and restaurant payment platform, Oracle Payment Interface.

Semi-integrated credit card terminals offer a secure and streamlined way to process payments by connecting the terminal directly to a middleware solution, eliminating the need to fully integrate it into the POS system. This setup also allows sensitive cardholder data to bypass the POS, reducing PCI scope and enhancing security.

By leveraging our OPI, businesses gain greater flexibility in managing payment processing, device updates, and compliance – without disrupting their core POS operations. Click on the tabs below to explore the different types of hardware our Micros OPI Middleware Connector supports, including:

PAX S300

1. The POS system sends the request to the EMV terminal for payment acceptance.
2. The EMV terminal sends the transaction request (cardholder data) directly to the processor for authorization.
3. The processor returns the authorization to the terminal, which passes the response to the POS system to finish the transaction.
