I was looking for a way to list what kind of credit cards we accept on the checkout page (not just info boxes). With the authorize.net module, on the checkout page, it would say something like, "Here is the acceptable types of payment: Authorize.net" Well, the average Joe doesn't know what Authorize.net is. In fact, we had someone call in and say, "I want to use my credit card and the only option I have is this authorize.net thing."

I didn't find a contribution or way to change this, so I made one. This is a pretty simple way to list (in text form) what credit cards you accept in the authorize.net payment module. Any improvements are welcomed:

Open /catalog/includes/languages/english/modules/payment/authorizenet.php

Find
Code:
  define('MODULE_PAYMENT_AUTHORIZENET_TEXT_TITLE', 'Authorize.net');
on about line 13.

Change (leave the apostrophes) 'Authoriz.net' to whatver text you want - I put 'Credit Cards - VISA, MASTERCARD, DISCOVER ONLY'

so it now looks like this:

Code:
define('MODULE_PAYMENT_AUTHORIZENET_TEXT_TITLE', 'Credit Cards - VISA, MASTERCARD, DISCOVER ONLY');
Save it and check it out!

Hope this helps!
