Request that the browser disable autocomplete for credit card fields

Hello, this uses the [HTML `autocomplete` attribute](http://www.w3.org/wiki/HTML/Elements/input/text) to prevent browsers from displaying a history of previously entered credit card numbers and CVCs. Some browsers (e.g. Chrome) must have a heuristic to disable autocomplete for form fields whose names match a certain pattern, but others do not and record sensitive data.

Thanks for your consideration.
