Making DCC work across authorization, settlement & disputes.

For any payment network, Dynamic Currency Conversion (DCC) is a complex feature.

Challenge

A payment network was implementing Dynamic Currency Conversion (DCC) across their regional operations. While DCC appears straightforward – allowing customers to see transaction amounts in their home currency – the implementation reality is complex.

DCC touches authorization, settlement, disputes, compliance, user experience, and operational processes. Each area has established market standards that must be met for competitive positioning and regulatory compliance.

The network needed comprehensive implementation guidance validated against industry best practices to ensure alignment before deployment.

Solution

We provided systematic implementation guidance through three-dimensional benchmarking against market standards.

1. Use Case Analysis

We analyzed their proposed solution coverage across DCC scenarios: card present and not present transactions, attended and unattended environments, e-commerce and contactless channels, and merchant verticals including ATM, transit, lodging, and retail. We compared how their approach handled scenario-specific requirements –transit authorization speed, lodging pre-authorization adjustments, ATM disbursement rules – against how other networks address these use cases.

2. Policy Framework Comparison

We benchmarked their policy framework against other networks across: regulatory compliance and disclosure requirements, product eligibility restrictions, oversight mechanisms for acquirer and merchant monitoring, conversion parameters and markup limits, cardholder consent requirements, and user interface standards. This comparison identified where their framework aligned with market standards and where differences existed.

3. Technical Specification Benchmarking

We compared their technical specifications against other networks: IIN table structures for DCC support indication, authorization message fields and values, settlement file formats and data elements, chargeback reason codes for DCC disputes, and solution architecture approach. We also benchmarked implementation specifics including return authorization handling, partial reversals, registration processes, transaction eligibility, rate source determination, and clearing currency specifications.

As a result, we delivered a comprehensive gap analysis and explanatory report with specific recommendations for achieving market alignment.

Results

The network's DCC implementation moved forward positioned for market success – validated against industry standards, gaps identified and addressed, implementation decisions informed by comprehensive market intelligence.
