There are many of ways of creating it;

1. By creating an observer for the event payment_method_is_active. Which is in fact the best technique to use.
2. By overriding your theme’s default template files: app/design/frontend/[PACKAGE]/[THEME]/template/checkout/onepage/payment/methods.phtml
3. By overriding method: Mage_Payment_Model_Method_Abstract::isAvailable()
4. By overriding method: Mage_Checkout_Block_Onepage_Payment_Methods::_canUseMethod()
5. By overriding method: Mage_Checkout_Block_Onepage_Payment_Methods::getMethods()

Among all the above methods, I’m discussing the first technique, i.e. creating an observer for the event payment_method_is_active.

Case Study: I have a magento store with two currencies, i.e. INR and USD, so, I would like to filter payment methods based on the currency customer has chosen. I will show only Saved CC Payment method for customers using USD as their currency.

Step 1

Create a Module in app/code/local/Insync/ Paymentfilter

Step 2

Register the event: payment_method_is_active in config.xml.

Add the following xml code in app/code/local/Insync/Paymentfilter/etc/config.xml

		
			1.0
		
	
	
		
			
				
					
						singleton
						Insync_Paymentfilter_Model_Observer
						paymentMethodIsActive
					
				
			
		
	

Step 3

Now, we need to create the observer file, where actual logic will be implemented.

Create observer file: app/code/local/Insync/Paymentfilter/Model/Observer.php and paste the following code:

Step 4 Now in this final step, enable & register your module with magento. Create the module xml file: app/etc/modules/Insync_Paymentfilter.xml and paste the following code:

	
		
			true
			local
			0.1.0
		
	

Now test it and Enjoy.
