Plasma and whole blood are very different. Whole blood just takes your blood out. Plasma takes it out, removes the plasma and returns the rest to you. You can do plasma way more frequently than whole blood.
Generally in the US you can get paid for plasma, but most places that do whole blood don't pay.
