# Click to Pay

> Set up Click to Pay as a digital wallet payment method in Gr4vy.

Click to Pay is a secure, guest-friendly checkout solution backed by major card networks (American Express, Discover, Mastercard, and Visa). It allows customers to complete purchases quickly without creating an account or manually entering card details.

## Key features

* **Guest Checkout**: No account or password required
* **Enrolled User Recognition**: Automatically identifies returning customers
* **Network Token Security**: Uses secure network tokens for payment processing
* **Advanced Security Options**: Token Authentication Service (TAS) and Customer Authentication Module (CAM)
* **Cross-Merchant Recognition**: Works across all participating merchant sites
* **Biometric Authentication**: Supports passkeys for enhanced security

## How it works

1. Customer enters their email at checkout
2. Click to Pay recognizes if they're enrolled
3. Customer authenticates using their preferred method
4. Customer selects from their saved cards
5. Payment completes using secure network tokens

## Benefits

* **Higher Conversion**: Faster checkout reduces cart abandonment
* **Enhanced Security**: Network token processing reduces fraud risk
* **Better UX**: No manual card entry or account creation needed
