FAQ
How does QA testing ensure compliance with regulations like PSD2 and GDPR in fintech apps?
QA testing validates that all user interactions, data processing and third-party integrations comply with regulatory requirements. This includes verifying consent flows for GDPR, Strong Customer Authentication (SCA) under PSD2, audit logs for transactions and secure handling of personally identifiable information (PII) across all touchpoints.
What types of performance issues most commonly impact fintech payment processing?
Common performance bottlenecks include slow response times during peak transaction volumes, timeouts in API calls to payment gateways or core banking systems, and race conditions in reconciliation processes. These issues can lead to failed transactions, customer frustration and financial penalties from payment networks.
How do you test fraud detection systems in fintech applications?
We simulate real-world attack vectors, including synthetic fraud patterns, credential stuffing attempts and anomalous transaction behaviors. Our testing covers both rule-based and AI-driven fraud detection engines, validating their accuracy, false positive rates and response times under load.
What role does QA play in KYC and identity verification workflows?
QA ensures that KYC workflows handle identity document uploads, biometric verification and liveness detection reliably across devices and networks. We test edge cases such as low-light conditions, poor connectivity and document fraud attempts, verifying that the system complies with AML regulations while maintaining a smooth user experience.
