Objective
This module equips engineering, compliance, product, and executive teams with a clear understanding of:- What compliance frameworks (like PCI-DSS) apply to virtual card systems
- How Visa, Mastercard, and other scheme rules affect what you build
- How to stay ahead of audits, regulator queries, and partner evaluations
- What technical and process controls must be in place to be compliant and audit-ready
Understanding PCI-DSS for virtual cards
PCI-DSS (Payment Card Industry Data Security Standard) is the global benchmark for how cardholder data is stored, processed, and transmitted. While your system may not be storing full PAN/CVV (as cards are issued via a licensed third party), you may still:- Display partial card data
- Transmit data during card creation, top-up, or spend
- Log metadata (e.g. last 4 digits, BIN, MCC)
- Proxy card information through your frontend or backend
Card scheme rules (Visa, Mastercard, etc.)
Your issuing partner is bound by Visa and Mastercard scheme rules, and so are you indirectly. Key expectations:
If your platform enables top-up → spend → withdraw, it may fall under stored value or e-money compliance zones, which triggers additional local obligations (e.g., in the EU, UK, or Nigeria).
Examples of compliance failures
Regulatory zones that may apply
Even if you’re not directly licensed, your platform must design for:
You are a regulated surface, even if not a licensed entity. Design like you’re regulated.
Partner due diligence readiness
Issuers, banks, and card processors may request due diligence and audit responses. You must be able to demonstrate:- Secure card issuance processes
- KYC enforcement prior to high-risk MCCs
- Card freeze/terminate workflows
- Refund reconciliation across wallet/float/card
- Transparent ledger tracking and transaction matching
- Chargeback handling playbooks
