Core Interfaces

Solution Summary

CSFi software provides real-time communications with other systems and services to approve debit card transactions. CSFi’s ATM/debit switching system connects to a host authorizing (or core banking) system which contains the important financial (checking/savings) information for each cardholder. It performs a financial request against their available balances to obtain approval, or decline. In most cases, CSFi software matches the debit card number to the checking/savings account number and then sends the request to the core banking system for online approval.
