Protecting customers’ payment information is crucial for trust and regulatory compliance. Strong security also reduces chargebacks and fraud-related losses.

• Stripe and PayPal comply with PCI DSS Level 1 and use tokenization and advanced fraud detection

• Square encrypts data and offers no chargeback fees on many transactions
