Payment is a kind of transaction. It is usually done after the terms of the exchange have been fulfilled. A payment can be made in the form of cash, cheque or through your credit or debit card.

Example:
For example, when you go to the market to buy a product (such as a bottle of shampoo) or a service (like going to the barber for a haircut), at the end of this exchange you make a payment in cash if you find the experience satisfactory.
