Security & PCI Compliance
Protection You Can Trust. Compliance Made Simple.
At St. Louis Merchant Services, security isn’t optional – it’s built into everything we do.
As cyber threats and payment fraud continue to rise, protecting your business and your customers’ card data is critical. That’s why every payment solution we provide is designed with advanced security and PCI compliance at its core.
What Is PCI Compliance?
The Payment Card Industry Data Security Standard (PCI DSS) is a set of security requirements created to protect cardholder data and reduce fraud.
If your business accepts credit or debit cards, PCI compliance is required — regardless of size or industry.
We make sure your payment environment meets those standards without adding unnecessary complexity to your operations.
How We Keep Your Business Secure
Our technology and processing platforms are designed to meet and exceed PCI DSS requirements, keeping your transactions protected at every stage.
PCI-Compliant Processing
All transactions are encrypted, tokenized, and processed through secure, PCI-compliant gateways to safeguard sensitive cardholder data.
Point-to-Point Encryption (P2PE)
Card data is encrypted immediately when a card is tapped, dipped, or swiped — protecting information before it even enters your system.
Payment Tokenization
Sensitive card numbers are replaced with unique tokens, making stored payment data useless to hackers. This is essential for recurring billing and cards-on-file.
EMV Chip Technology
EMV-enabled terminals reduce counterfeit fraud and help minimize chargeback risk through secure authentication at the point of sale.
Fraud Prevention Tools
Real-time monitoring, Address Verification (AVS), and CVV authentication work together to prevent unauthorized transactions before they occur.
Online Payment Security
Hosted checkout pages, payment links, virtual terminals, and mobile solutions are SSL-secured and encrypted to protect remote transactions.
