Secure Payment Systems

From credit card processing to ACH transfers and Check 21 imaging, we build payment infrastructure that handles real money safely.

What We Build

WSV builds payment systems for businesses that need to move money securely and at scale. We integrate with card networks, banking rails, and imaging systems. Every system is PCI DSS compliant by design, not bolted on afterwards.

  • Credit and debit card processing
  • ACH payment origination and receipt
  • Check 21 image capture and clearing
  • PCI DSS Level 1 compliant architecture
  • Merchant onboarding and KYC workflows
  • Payment gateway integration and custom builds
  • Recurring billing and subscription management
  • Real-time transaction monitoring and fraud rules

How It Works

A regional lender needed to replace a legacy card processing system that was failing PCI audits. We rebuilt the payment stack on modern infrastructure with end-to-end encryption, tokenisation, and automated compliance reporting. Processing volume increased by 40% with zero security incidents in the first year.

An e-commerce platform required ACH direct debit for high-value B2B transactions. We integrated with the ACH network, built automated reconciliation, and added same-day settlement support. Transaction costs dropped by 60% compared to their previous card-only setup.

A cheque processing company needed to modernise from physical clearing to Check 21 electronic imaging. We built the image capture pipeline, quality validation, and substitute check generation. Processing time went from 3 days to same-day.
