We currently have 26 credit card questions questions and 47 payment questions. I'm not sure how much overlap there is between the two. At least some of the credit card questions could be tagged with validation, but I'm wondering if the site would benefit from a new payment-system tag. I'm thinking this would help our search engine optimization and programmers looking into implementing such things.
What do you think? Good tag?
It seems there's some interest in this, but I'm unsure of a good name. Which would be best?
