Why do debit card companies want you to slide your debit as a credit card?

[crida]

I joined this pursuit added items announcement poo. Furthermore obviously, to increase focuses, I can just swipe my check card as a credit, keeping in mind the end goal to get focuses. Why is this the case, and why do such a variety of credit/debit associations sway you to swipe your DEBIT card as a MasterCard and mark? Much obliged, all answers are relished.
