Final answer:
In national credit card sales, there are 3 parties involved: the credit card company, the seller, and the credit card user. The credit card acts as a short-term loan where money is transferred from the credit card company's checking account to the seller, and the user is required to pay it back at the end of the month.
Step-by-step explanation:
In the national credit card sales, there are 3 parties involved: the credit card company, the seller, and the credit card user.
When a credit card is used for a purchase, the money is immediately transferred from the credit card company's checking account to the seller. At the end of the month, the credit card user owes the money to the credit card company.
A credit card can be seen as a short-term loan, as the user is borrowing money from the credit card company and is required to pay it back.
