Square Payment Form provides secure, hosted components for payment data like card number and CVV, while enabling you to make it your own. It’s designed to help buyers enter their card data accurately and quickly. It’s also designed to ensure PCI compliant payment processing: Card data is collected securely and tokenized, never hitting your servers.

We provide a platform for commerce, not just payments. Associate transactions with itemized orders, products, customer profiles, and more. Configure product catalog and inventory to automatically sync between online properties and Square Point of Sale.
