## Usage Notes

* **CVV**: You can use any 3 numerical digits
* **Expiry Date**: Any future date is accepted
* **Password/PIN**:
  * `*` means no password/PIN required
  * For challenge flow with authentication successful, use exactly `101010!` (case-sensitive)
  * For authentication failure, use any incorrect PIN

## Testing Scenarios

### Without 3DS Authentication

Use these cards when testing payments that don't require additional authentication:

* **Success**: Use `4556218578001529` to simulate a successful payment
* **Decline**: Use `4804262554494753` to simulate a declined payment

### With 3DS - Frictionless Flow

These cards trigger 3D Secure authentication but complete without user interaction:

* Test various authentication and authorization outcomes
* No password/PIN required (marked with `*`)

### With 3DS - Challenge Flow

These cards require user input during authentication:

* Use `101010!` as the password for successful authentication
* Use any incorrect PIN to test authentication failure scenarios
