# CVC only

Use our Web SDK to capture your customer's CVC which you can use to take a card on file payment alongside a previously created token.

Note
You can only use the CVV only SDK if you have previously received a [verified token](/products/verified-tokens/create-verified-token) from an initial payment with the same card details.

JavaScript

      }

        event.preventDefault();
        checkout.generateSessionState(function(err, session) {
          if (err) {
            // handle session state generation error
            return;
          }

          // session state for cvc
          alert(session);
        });
      });

      clear.addEventListener("click", function(event) {
        event.preventDefault();
        checkout.clearForm(function() {
          // trigger desired behavior on cleared form
          console.log('Form successfully cleared');
        });
      });
    }
  );
})();

## Creating your checkout form

You must use unique identifiers and field configuration when creating your form. You must then apply default heights to your fields.

Here is an example of how you would set unique identifiers for your field configuration:

### HTML

<section class="container">
    <section class="card cvv">
        <form class="card__form checkout" id="cvv-form">
            <section class="field" id="cvv-field"></section>
            <button type="submit" class="submit">Submit</button>
        </form>
        <button class="clear" id="clear">Clear</button>
    </section>
</section>

<script src="https://try.access.worldpay.com/access-checkout/v1/checkout.js"></script>

// For production change to "https://access.worldpay.com/access-checkout/v1/checkout.js"

And an example of how you could set the layout of your CVC form:

### CSS

body {
  font: 11px/22px sans-serif;
  text-transform: uppercase;
  background-color: #f7f7f7;
  color: black;
}

.container {
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
}

.card {
  position: relative;
  background: white;
  padding: 40px 30px;
  top: -30px;
  width: 100%;
  max-width: 300px;
  border-radius: 12px;
  box-shadow: 3px 3px 60px 0px rgba(0, 0, 0, 0.1);
}
.card .checkout .col-2 {
  display: flex;
}
.card .checkout .col-2 .col:first-child {
  margin-right: 15px;
}
.card .checkout .col-2 .col:last-child {
  margin-left: 15px;
}
.card .checkout .label .type {
  color: green;
}
.card .checkout .field {
  height: 40px;
  border-bottom: 1px solid lightgray;
}
.card .checkout .field#card-pan {
  margin-bottom: 30px;
}
.card .checkout .field.is-onfocus {
  border-color: black;
}
.card .checkout .field.is-empty {
  border-color: orange;
}
.card .checkout .field.is-invalid {
  border-color: red;
}
.card .checkout .field.is-valid {
  border-color: green;
}
.card .checkout .submit {
  background: red;
  position: absolute;
  cursor: pointer;
  left: 50%;
  bottom: -60px;
  width: 200px;
  margin-left: -100px;
  color: white;
  outline: 0;
  font-size: 14px;
  border: 0;
  border-radius: 30px;
  text-transform: uppercase;
  font-weight: bold;
  padding: 15px 0;
  transition: background 0.3s ease;
}
.card .checkout.is-valid .submit {
  background: green;
}

.clear {
  background: grey;
  position: absolute;
  cursor: pointer;
  left: 50%;
  bottom: -120px;
  width: 200px;
  margin-left: -100px;
  color: white;
  outline: 0;
  font-size: 14px;
  border: 0;
  border-radius: 30px;
  text-transform: uppercase;
  font-weight: bold;
  padding: 15px 0;
  transition: background 0.3s ease;
}

## Initializing the SDK

Once you've included the [script](/products/checkout/web#get-our-sdk) to get our SDK and set your form and fields configuration, you must initialize the SDK.

Use the `Worldpay.checkout.init` method to do this.

You must provide your `AccessCheckoutIdentity`, unique form identifier, and field configuration when initializing the SDK.

Optionally you can also provide your [styling configuration](/products/checkout/web/v1/styles).

Here is an example of how you would initialize the SDK and the parameters/ configurations you must include:

(function () {
  var form = document.getElementById("cvv-form");
  var clear = document.getElementById("clear");
  Worldpay.checkout.init(
    {
      id: "your-checkout-id",
      form: "#cvv-form",
      fields: {
        cvvOnly: {
          selector: "#cvv-field",
          placeholder: "CVV"
        }
      },
      styles: {
        input: {
          "font-size": "14px",
          "font-family": "Arial"
        },
        "input.is-valid": {
          color: "green"
        },
        "input.is-invalid": {
          color: "red"
        }
      },
      accessibility: {
        ariaLabel: {
          cvvOnly: "my custom aria label for cvvOnly input"
        },
        lang: {
          locale: "en-GB"
        },
        title: {
          enabled: true,
          cvvOnly: "my custom title for security code"
        }
      }
    },
    function(err, checkout) {
      if (err) {
        // handle init error
        return;
      }
      form.addEventListener("submit", function(event) {
        event.preventDefault();
        checkout.generateSessionState(function(err, session) {
          if (err) {
            // handle session state generation error
            return;
          }

          // session state for cvc
          alert(session);
        });
      });

      clear.addEventListener("click", function(event) {
        event.preventDefault();
        checkout.clearForm(function() {
          // trigger desired behavior on cleared form
          console.log('Form successfully cleared');
        });
      });
    }
  );
})();

| Parameter | Required | Description |
|  --- | --- | --- |
| `id` | ✅ | Your AccessCheckoutIdentity. |
| `form` | ✅ | Your unique form #id selector. |
| `styles` | ❌ | Your **optional** styles object configuration. |
| `fields` | ✅ | The object that contains your field configurations. |
| `selector` | ✅ | The #id selector for a given field. |
| `placeholder` | ❌ | An **optional** text preview showing your customer the type of information they should enter in the field. |


You must provide the `cvvOnly` object in the `fields` configuration as shown in this example:

#### JavaScript


```
fields: {
        cvvOnly: {
          selector: "#cvv-only",
          placeholder: "123"
        },
      },
```

Use the value of the cvv `session` and the verified token from your initial request in our card/checkout `paymentInstrument` to take a card on file payment.

Important
The `session` has a lifespan of one minute. If you do not take a payment within that time, you must create a new `session`.

This `paymentInstrument` can be used in any of our card on file resources ([payments:cardonFileAuthorize](/products/card-payments/v6/authorise-a-cardonfile-payment), [payments:migrateCardOnFileSale](/products/card-payments/v6/migrate-cardonfile-sale) and [payments:migrateCardOnFileAuthorize](/products/card-payments/v6/authorize-a-payment#-migratecardonfile-authorization)).
