Magento - Add instructions to payment method

Question

I'd like to display some instructions/info whenever a user selects a certain payment method. How can I add this information to my payment module/method?

(I have another payment method that displays a form to fill in credit card data, but in this case I'd just like to display a bit of text)

Answer 1

The Payment Method Model variable

protected $_infoBlockType;

is responsible for showing info block. Check

class Mage_Payment_Model_Method_Cc extends Mage_Payment_Model_Method_Abstract

and

class Mage_Payment_Block_Info_Cc extends Mage_Payment_Block_Info
