What Is Payment Terminal Integration?
Payment Terminal Integration connects the terminal, EMV Kernel, payment application, host and backend systems required to complete a payment transaction. A modern terminal cannot operate effectively with hardware alone.
Each component must exchange the correct data and responses to ensure smooth processing and support EMV Level 3 readiness.
