UniTerm® is a small, sophisticated, EMV certified and PA-DSS validated software application that facilitates software integrations for performing EMV (chip and pin) card transactions with the Monetra® payment server software. UniTerm® provides a simple application interface and securely manages the EMV transaction process. The POS application software simply sends a transaction request to the UniTerm component. UniTerm then interacts with the terminal and the Monetra server software as required to perform the requested transaction, and returns the results to the POS app. UniTerm® is designed to securely handle all sensitive card data, keeping POS application software “out-of-scope” for PCI PA-DSS validation requirements.
