Our client, a leading private bank in Bangladesh needed to pre-certify their acquirer and issuer host for Discover Global Network’s D-PAS DCI certification.
They had dedicated in-house debugging and certification teams. Despite this, they faced numerous challenges:
- Waiting for limited certification slots with the network
- Managing complex test environments
- Manual debugging cycles that slowed down deployment
To overcome these challenges, the bank evaluated multiple tools that provide acquirer and issuer host testing capabilities for Discover D-PAS debugging.
After careful evaluation, they chose to go with Payhuddle’s Lithos.
Why did they choose Lithos?
It was a strategic fit for certification and debugging.
Lithos stood out for a number of compelling reasons:
Test Management
- Centralized test case management
- Integrates test cases, testing, and automatic analyzer
- Configurable test cases are aligned with certification requirements
Functionality
- Dual-use tool for both debugging and certification readiness testing
- Supports ISO 8583:1987 & ISO 8583:1993
- Cloud-based simulator for issuer, acquirer, and network testing
Discover-certified tool with Discover DCI ATS and ITS support for host certification
Flexibility and cost-effectiveness
