Caldera Forms credit card secret code (CVC) fields are are special fields design to work with credit card number fields for entering and validation credit card numbers.
To add a credit card CVC field, drag the New Field icon into the form layout editor where you want it to appear. This opens a modal that allows you to choose fields. Select the eCommerce section and then click on Credit Card CVC. You must then give your field a name.
All other settings fields are optional and are very similar to the settings for a text field. It is recommended that once this field is added, you link it to a credit card number field, using the settings of the credit card number field.
