# Validate a credit card

Validating a credit card lets you determine if a given credit card number and expiration date are valid.

## Example

Call the `ChargeOver.CreditCard.validate(...)` method to validate credit card information.

```javascript

var my_data = {
	number: '4111 1111 1111 1111',
	expdate_month: 7,
	expdate_year: 2016,
	name: 'John D Doe'

	// CVV/CSC card security code (used only for card validation, not stored)
	// cvv: '',

	// Optional address information (can be used for address verification)
	// address: '',
	// city: '',
	// state: '',
	// postcode: '',
	// country: ''
};

function my_callback_function(code, message, response)
{
	if (code == 200)
	{
		alert('Valid!');
	}
	else
	{
		alert('Not valid!');
	}
};

ChargeOver.CreditCard.validate(my_data, my_callback_function);
```
