I'm working on creating a site that will sell promotional items to businesses. I'm going to need a shopping cart (I'm using OSCommerce) and I'll need to be able to accept credit card information, but don't need to authorize the info online (not yet anyway). My supplier handles that part along with shipping, etc.
What do I need to be able to accept payment information securely? I'm new to this part of web development and I've never used certificates or secure servers before and I do not yet have either one. I need to find some info on how they work and what I need.
