I didn't want to thread hi jack the other thread about payment process but it looks like there are some people who work in that industry who could answer my question.

I have always wondered why business credit cards have much higher sign up bonuses and rewards than personal credit cards. Is that because the issuers can charge higher swipe fees for these types of cards?

I have applied for business cards with ridiculous applications (i.e. claim $100 in yearly revenue) and still get approved for cards with $10k+ limits and $750 sign up bonus.
