The reconciliation application is a robust 3-tier system designed to facilitate the 3-way reconciliation of Virtual Credit Cards (VCC) used as surety for accommodation bookings. It ensures operational transparency and fraud prevention through the following features:

1. Daily Alerts: Automatically notifies users to cancel VCCs for canceled or completed bookings, mitigating the risk of fraud and maintaining credibility.

2. Maker-Checker Model: Implements a two-step approval process where exceptions to keep a VCC active must be manually justified by the user (Maker) and subsequently approved by a manager (Checker).

3. Dashboards: Provides intuitive dashboards at various user levels, offering real-time insights into the status and performance of VCC reconciliation processes.

4. Azure Active Directory Integration: Ensures secure user authentication and access management.

5. Comprehensive Logging: Maintains a detailed application log for full traceability and compliance.

This system promotes efficiency, enhances security, and ensures accountability in managing virtual credit cards for accommodation bookings.
