Frequently asked questions

FAQ

How do custom payment gateways improve fraud detection for fintech companies?

Custom gateways integrate advanced fraud detection tools like tokenization, 3D Secure authentication, and machine learning models trained on real transaction patterns. Unlike generic solutions, they allow fintech firms to adjust detection thresholds based on their specific risk tolerance and regulatory requirements, reducing false positives while maintaining compliance with frameworks like PSD2 or local AML laws.

Can a payment gateway support both ACH and card transactions for a fintech platform?

Yes, modern payment gateways designed for fintech platforms typically support multiple payment methods, including ACH, credit/debit cards, and digital wallets. This flexibility is crucial for fintech companies targeting diverse user bases, as it ensures broader accessibility while optimizing transaction costs and settlement speeds.

What compliance features should a payment gateway include for fintech startups in the US?

A compliant payment gateway for US fintech startups must support PCI DSS Level 1 certification, AML/KYC integration, and real-time reporting for regulatory bodies. It should also include features like secure vault storage for payment data and automated reconciliation to streamline audits and reduce manual errors.

How scalable are custom payment gateways for high-growth fintech companies?

Custom gateways are built for scalability, allowing fintech companies to handle peak transaction volumes without downtime. They support horizontal scaling, microservices architecture, and cloud-native deployments, ensuring low latency even as transaction volumes grow. This is particularly important for fintech firms experiencing rapid user adoption or expanding into new markets.
