Best Practices:

• Use credit cards over debit for online purchases

• Use different cards for online vs. in-person shopping

Digital Wallets (Very Secure)

Modern digital wallets add extra security layers:

What to Avoid

Certain payment methods offer little to no fraud protection:

Never Use:

• Wire transfers: No fraud protection, irreversible
• Cryptocurrency: No buyer protection, transactions final
• Gift cards: Untraceable, no refunds or protection
• Money orders/checks: Slow, limited fraud protection
• Bank transfers: Direct bank access, difficult to reverse

Debit Cards (Use with Caution):

• Direct access to checking account
• More limited fraud protection than credit cards
• Potential for account drain while investigating fraud
• Fewer dispute rights
• If using debit: Enable low balance alerts, use only with trusted retailers

Checkout Security

Verify HTTPS and Security Certificates

Before entering payment information, verify secure connections:

HTTPS Verification:

• Look for padlock icon in browser address bar
• URL must start with “https://” (not just “http://”)
• Click padlock to view security certificate details
• Ensure certificate is valid and issued to correct company
• Check certificate hasn’t expired

Warning Signs:

• Browser security warnings
• Missing or broken padlock icon
• URL shows “Not Secure” warning
• Expired security certificates
• Certificate issued to different company

Action: Never enter payment information without HTTPS. Close the website immediately if security warnings appear.

PCI DSS Compliance

Payment Card Industry Data Security Standard (PCI DSS) ensures secure payment processing:

What PCI Compliance Means:

• Encrypted payment data transmission
• Secure payment gateway infrastructure
• Regular security testing and audits
• Limited access to cardholder data
• Strong password and access controls

How to Verify:

• Look for PCI compliance statements in footer
• Check “Security” or “Payment Information” pages
• Verify with recognized payment processors (Stripe, PayPal, etc.)
• Research retailer’s security practices
• Contact customer service to confirm compliance

Secure Checkout Process

Legitimate retailers follow secure checkout procedures:

Good Security Practices:

• Encrypted connection (HTTPS) throughout checkout
• Minimal required information (no SSN for purchases)
• Clear privacy policy about data usage
• CVV/security code required for card verification

• Order confirmation sent to email
• No storage of full card numbers

Red Flags:

• Requesting excessive personal information
• Asking for SSN or driver’s license number
• Storing full card numbers on your account
