Insider Technologies RTLX is a real-time monitoring and tracking solution designed to provide end-to-end visibility for high-volume electronic payments and transactional processes. It specifically ensures that every stage of a payment—from the initial card “tap” at a point-of-sale (POS) terminal to the final movement of funds from an account—is monitored to maintain operational continuity.

RTLX Overview
- Function: Real-time transaction and payment monitoring.

- Core Value: Simplifies “Big Data” for IT operations by alerting teams to potential failures before they impact consumers (e.g., preventing ATM or online banking outages).
