I am needing to create a payment module for a debit card used by local college students here (my main clientele) issued by the local university.

I am wondering if it is going to be easier for me than others asking for help here, as I don't need a gateway/API, but only need to receive the card number, then will process it offline. I currently do the same thing with credit cards. I have thought about adding it as a new card in the CC module, but my problem is, I need to restrict certain categories from being purchased if the college card is used, so I need to have a seperate module, yes?

Thanks for the help. I have just started building this module, and am unsure how I need to proceed, but looks like I can gain alot of knowledge through the previous posts here.
