What is the difference between a cash back program and a rewards program?

There are many flavors of rewards programs, and Cash Back is one of them.

You answered your own question. Rewards are built by points. Such as however many dollars spent is 2 points for every dollar. You accumilate points and then you get a choice depending on the number of points you earned. Money back is basically you get a percentage back to your card for each let's say $100 spent you get back 5% as a credit.
I used to work for a credit card industry a very very large bank. They are designed to get people to sign up and spend.
