What is a credit card cashback?

@montana 

A credit card cashback refers to a rewards program offered by some credit card issuers, where cardholders can earn a certain percentage of their purchases back as cash rewards. This means that for every qualifying purchase made using the credit card, a small percentage of the purchase amount is credited back to the cardholder's account as cashback. The cashback earned can be accumulated and redeemed for future purchases, credited to the cardholder's statement, or withdrawn as actual cash. The percentage of cashback offered varies depending on the credit card and the type of purchase.
