Changing the name of a payment processor on the front end
There are many ways to do this. 2 easiest

1) Change the name of the payment processor in /civicrm/admin/paymentProcessor

The problem with this approach is it becomes less clear to you the administrator.

2) A *hack*, go to your current registration page where the radio buttons to choose payment processor appear. Find the &lt; div > tag that encompasses both using your browsers debug tools(right click, inspect element). Record the id(id="xxx") of that div.

in the confirmation screen or registration screen(which screen do the radio buttons appear on in your event) open the the WYSIWYG editor for introductory text and  click on the source button.

Then, enter the following javascript. at the very top, above any text you may have entered.(replace xxx with id you found before)

&lt;script type="javascript/text"&gt;
    var divOfInterest = document.findElementById("xxx");
    var replacements = {"Stripe":"CreditCard", "Paypal":"Your Paypal Account", "payment3":"betterlabel"};

    for (var toReplace in replacements) {
        divOfInterest.innerHTML = divOfInterest.innerHTML.replace(toReplace, replacements[toReplace]);
    }

&lt;/script&gt;


Again, make sure you clicked the 'source' button on the WYSIWYG editor. Also, make sure you are adding your javascript to the correct Intro text(prob in registration or confirmation)

Note: this will replace any instance of the word "Stripe" with credit card in that &lt; div >.
