# Makes CVC optional when presenting a payment method on a simulated reader

## What’s new

CVC is now an optional field for [present_payment_method](https://docs.stripe.com/api/terminal/readers/present_payment_method.md?api-version=2025-08-27.basil) card objects.

## Impact

You no longer need to enter CVC as a card parameter to [present a payment method](https://docs.stripe.com/api/terminal/readers/present_payment_method.md?api-version=2025-08-27.basil) on a simulated reader.
