Add new credit card

[ngr]

Hello.
I´ll process credit cards manually offline so i enable the CC payment module.
What i need to do now is to accept a different credit card type, not listed in Zen Cart. It´s a regional credit card and start with "589892"(14 digits in totall).
It´s possible to start accpeting these type of cc using the actual cc.php module???

thanks!, and have a happy new year!
